Ecosense EcoTracker

Each of the four EcoTrackers holds a pulsed ion chamber. When radon in the chamber decays, it gives off alpha particles, and the monitor counts them. Ecosense states a sensitivity of 30 counts per hour per pCi/L and a measurement range of 0.2 to 255 pCi/L (7 to 9,435 Bq/m³). The user guide shows the counting at work: a line on the screen gives the alpha counts in the current and previous 10-minute cycles, and Ecosense explains that the larger the count, the higher the radon value. Above 255 pCi/L the screen reads OVER.

What sets the EcoTracker apart is how it reports. Ecosense describes three modes. The 5-minute Sniff Mode, the default, updates and logs a reading every 5 minutes, and the product page says the first reading appears 5 minutes after setup; the 10-minute Sniff Mode does the same every 10 minutes. Ecosense's firmware notes say that from version 1.03A each Sniff Mode averages its readings as they come in and, after six 5-minute or three 10-minute points, switches to a 30-minute moving average. The Continuous Radon Monitoring (CRM) mode updates every 10 minutes and logs once an hour, for measurements left in place over hours or days. Each monitor can be set to its own mode.

Each monitor has a 0.96-inch OLED screen that shows the current reading and mode, hourly, daily and monthly averages since power-on, the peak reading and the total measurement time, plus a Bluetooth symbol, an LED and a vibration indicator that lights if the monitor is moved from where it was placed. Those on-screen averages reset when a monitor is switched off and on again, while the logged data stays in the device. Storage depends on the mode: about 1 month in 5-minute Sniff Mode, 2 months in 10-minute Sniff Mode and 1 year in CRM mode. Switching between modes resets the data, and the app first asks whether to save it.

The four monitors talk to the EcoTracker by Ecosense app over Bluetooth Low Energy. Ecosense says no Wi-Fi, cellular connection or internet access is needed to view readings and manage the devices on site, and that the app shows all four detectors side by side, with historical data and charts. The guide lists iOS 13 and Android 5.0 or later. From the app a user sets each monitor's mode and units (pCi/L or Bq/m³), turns its audio alarm on or off with a threshold and interval, saves log files and exports them by email or text message. Ecosense's EcoTracker documents describe log files, not a web dashboard or a report generator.

Power comes from a 12 V DC adapter for each monitor, rated at 0.1 A. Ecosense says the EcoTracker has no internal battery backup; for portable use, a standard 5 V battery pack can run a monitor through the supplied 5 V to 12 V step-up cable, which Ecosense puts at about 72 hours on a 20 Ah pack and about 105 hours on a 30 Ah pack. The guide gives an operating range of 32 to 104°F (0 to 40°C) at relative humidity under 80%, and lists each monitor as Φ80 mm x 120 mm and 240 g.

On the independent side, neither the National Radon Safety Board's list of approved devices, dated July 2026, nor C-NRPP's list of approved professional-grade electronic radon monitors includes the EcoTracker; under Ecosense both name the RadonEye Pro (RD200P). Ecosense describes the CRM mode as intended for longer-term measurements for professional testing and analysis, but makes no listing or certification statement for the EcoTracker in its product page, overview or user guide. C-NRPP's 2024/25 evaluation covered consumer monitors, so the EcoTracker was not part of it.
