About this item

As AEGTEST states it

  • How it measures: High-sensitivity pulsed ionization chamber (maker's words); sampling method not stated by the maker
  • First reading: Within 10 minutes
  • Reading updates: First reading in 10 minutes, stable data within 1 hour, automatic updates every 10 minutes
  • Display and app: Built-in display
  • Power: Battery: Rechargeable battery; charging data cable in the box; capacity and runtime not stated by the maker

The HOUND-3786 is a rechargeable radon monitor from AEGTEST with a pulsed ionization chamber, a 3.5-inch color LCD and built-in charts: AEGTEST gives a first reading in 10 minutes, stable data within 1 hour and updates every 10 minutes, over 1.5 years of stored history, and PDF reports for a phone or computer with no app. AEGTEST publishes no measurement range, units, accuracy or manual for it, and it was not included in C-NRPP's 2024/25 consumer monitor evaluation.

What you get

AEGTEST lists one HOUND-3786 radon detector, a charging data cable and a multilingual user manual. The manual is in the box only: AEGTEST posts no copy online, and the general help page of its earlier store asked buyers looking for the instruction guide to contact the company. AEGTEST does not publish the size or weight of the HOUND-3786.

How it works

In our words, from the maker's documents

AEGTEST says the HOUND-3786 uses a high-sensitivity pulsed ionization chamber to follow radon levels that fluctuate constantly. It does not describe the chamber further or say whether air reaches it by diffusion or with a pump, so the sampling method is not stated by the maker. AEGTEST's earlier store gave a general account of how its detectors measure: the sensor counts the alpha particles of radon in each sample of air it analyzes, and the longer the measurement runs, the more data points it has and the more accurate the readings become.

The first reading comes 10 minutes after starting, AEGTEST says, with stable data within 1 hour and automatic updates every 10 minutes after that. The device draws its own charts of the readings on the screen, so short-term and long-term trends can be read without a computer, and it stores over 1.5 years of history.

The screen is a large 3.5-inch color LCD, worked with button controls, and color-coded bars show the radon level at a glance. AEGTEST says the device lets you export PDF reports easily to a phone or computer, with no app or lab needed. It does not say how the export is made, so the route is not stated by the maker.

AEGTEST's product text gives no measurement range, no units and no accuracy figure for the HOUND-3786, and no operating temperature or humidity. The words fast and accurate on its page come with no percentage, test level or test period. So the range, the units, the accuracy and the operating conditions are not stated by the maker, and AEGTEST posts no manual online where they could be checked.

Power is a rechargeable battery, and AEGTEST lists a charging data cable in the box. It gives no capacity, runtime or charging time, and calls the HOUND-3786 ideal for long-term daily use at home, in a basement or in an office. For warnings it lists color-coded bars, flashing LED indicators and customizable audible alarms; it does not say what level sets the alarm off or what can be customized, so the alarm level is not stated by the maker.

Independent evidence

C-NRPP 2024/25, recalls and studies

C-NRPP 2024/25
Not included in C-NRPP's 2024/25 evaluation

The Canadian National Radon Proficiency Program's 2024/25 comparison of consumer monitors did not include AEGTEST HOUND-3786. That is a fact about which devices took part, not a finding about this one: no result from that program exists for it either way.

Recalls
No Health Canada recall or advisory names this device.
Peer-reviewed studies
We found no peer-reviewed comparison that names this model.
Notes
  • No Health Canada recall or advisory and no CPSC recall names AEGTEST or a HOUND device, and C-NRPP's consumer monitor page lists none, approved or not approved (checked 2026-10-08).

C-NRPP is the Canadian National Radon Proficiency Program. Its 2024/25 results were published in May 2025.

What is in the box

AEGTEST lists one HOUND-3786 radon detector, a charging data cable and a multilingual user manual. The manual is in the box only: AEGTEST posts no copy online, and the general help page of its earlier store asked buyers looking for the instruction guide to contact the company. AEGTEST does not publish the size or weight of the HOUND-3786.

AEGTEST's warranty page, which covers its store as a whole, promises a three-year warranty, described as a 36-month after-sales service with lifetime technical support. It excludes faults caused by unauthorized disassembly, damage from water or strong mechanical force, and normal wear that does not affect function, says AEGTEST is not responsible for loss of use or incidental damages, and points buyers to AEGTEST's support email for warranty help or repair.

What it costs to run

There is no lab fee and no battery to buy: the battery is rechargeable, and AEGTEST lists a charging data cable in the box. AEGTEST says the PDF reports need no app or lab, mentions no subscription or cloud service, and publishes no sensor life, recalibration interval or service schedule for the HOUND-3786.

Fit and setup

The fit, then setup and placement as the guidance asks

Who it fits

Good fit if, and look elsewhere if

Good fit if

  • You want a first number within minutes and a fresh reading every 10 minutes.
  • You want a large screen with charts on the device, and PDF reports without an app.
  • You want a rechargeable monitor you can move between rooms, a basement or an office.
  • You want a warranty term longer than one year.

Look elsewhere if

  • You want a stated measurement range, units or accuracy before buying; AEGTEST publishes none of these for the HOUND-3786.
  • You want to know how long it runs between charges; AEGTEST gives no battery capacity or runtime.
  • You want a monitor that has been through C-NRPP's evaluation; the HOUND-3786 was not included in its 2024/25 round.
  • You need a result for a home sale; check what your state accepts before relying on any consumer monitor.

Setup and placement

3 steps

  1. AEGTEST publishes no placement rules for the HOUND-3786 beyond calling it ready to use right out of the box with simple operation. The general help page of AEGTEST's earlier store, not a page about the HOUND-3786, gave two cautions for its detectors: strong light and humidity can affect reading accuracy, and a new unit can read high at startup because it is exposed to radon during final factory testing. The fix there was to blow on the air inlet with a fan for a few minutes, then restart the measurement.
  2. The EPA's guidance for any home radon test fills the gap: test on the lowest lived-in level of the home, in a room used regularly but not the kitchen or bathroom, at least 20 inches above the floor, and away from drafts, high heat, high humidity and exterior walls.
  3. AEGTEST gives stable data within 1 hour for the device's readings, and its text does not say how long to test a home. The EPA notes that radon levels tend to vary from day to day and season to season, and C-NRPP's advice for any consumer monitor is to place it in a room occupied at least 4 hours a day, test for a minimum of 3 months, preferably in the heating season, and decide on the long-term average, with a follow-up long-term test if you have less than 91 days of data. The EPA's guidance is to fix a home at 4 pCi/L or more and to consider fixing between 2 and 4 pCi/L.

How C-NRPP says to use any consumer monitor

  • Leave it in place for at least three months, ideally through the heating season, when indoor radon tends to be highest.
  • Put it in a room someone uses for at least four hours a day.
  • Decide about fixing your home from the long-term average, not a single day or week.
  • If you can only run a monitor for less than 91 days, follow up with a long-term test.

Questions

Questions people ask

5 questions about the AEGTEST HOUND-3786, answered

Asked about the HOUND-3786

Who makes the HOUND-3786?

AEGTEST, which sells it on its own online store. The store's own record gives Shenzhen, Guangdong, China as its location and prices in US dollars, and lists the United States among the countries it ships to. The AEGTEST trademark is registered in the US to Shenzhen Xunyi Electronic Commerce Co., Ltd., with radon detectors among the goods it covers.

What range and units does the HOUND-3786 measure in?

AEGTEST does not say. Its product text gives neither a measurement range nor the units the screen uses, and there is no manual online to check. If those figures matter to you, ask AEGTEST before buying.

How accurate does AEGTEST say it is?

AEGTEST gives no figure. Its page calls the detection fast and accurate and the chamber high-sensitivity, but names no percentage, test level or test period.

There is no independent result either: the HOUND-3786 was not included in C-NRPP's 2024/25 consumer monitor evaluation. That is not a failed test; it means no independent result exists.

How do I get the readings onto a computer?

AEGTEST says the HOUND-3786 lets you export PDF reports easily to your phone or computer, with no app or lab needed, and it lists a charging data cable in the box. It does not say how the export is made, over that cable or another way, so the route is not stated by the maker; if it matters to you, ask AEGTEST before buying.

How is it different from the HOUND-3699?

Both are AEGTEST pulse ionization detectors that refresh every 10 minutes and make PDF reports. AEGTEST says the HOUND-3699 exports its reports to a computer with the included cable; for the HOUND-3786 it names a phone or computer and does not say how. The HOUND-3786 has a 3.5-inch color LCD with button controls and stores over 1.5 years of history. The HOUND-3699 has a 2.1-inch touchscreen and alert thresholds you can set, stores up to 1 year of data, and its earlier store page listed a range and accuracy figures that AEGTEST has not published for the HOUND-3786.
