EcoQube Flex is a portable, battery-powered radon monitor with a precise pulsed ionization chamber. Because it needs neither a power socket nor Wi-Fi, you can place it anywhere – in the basement, a bedroom or a holiday home. Insert the batteries and it starts measuring automatically, showing the first reading on the display after 10–15 minutes. It is ideal for testing a house or apartment room by room, before buying a property, or for checking how well radon mitigation has worked.

Key advantages:

• No cables: runs on two AA batteries – up to 7 years without app connection, or about 2 years with regular syncing.
• Everything on the display: the always-on e-ink screen shows the current level, averages, and the highest and lowest values for the selected period – you can spot night-time peaks without your phone.
• Fast results: first reading after 10–15 minutes, a reliable result within the first hour.
• High accuracy: patented pulsed ionization chamber, the same technology as in the EcoQube (±10% at 370 Bq/m³ after 10 hours).
• Room-by-room comparison: save results for each room, floor or building separately in the app and compare them – for example, your basement in winter and in summer.
• Audible alarm: sounds when the level exceeds your set threshold (by default 300 Bq/m³ for Europe, matching the EU and Slovenian reference level). The color scale on the display flags values above the 100 Bq/m³ reference level recommended by the WHO.

Good to know:

• Placement: at least 50 cm above the floor and 1 m from windows and doors, away from vents, kitchens and bathrooms. Let it measure for 2–7 days in each room before moving it.
• No remote access: without Wi-Fi, data transfers to the app via Bluetooth when your phone is nearby. For remote monitoring, choose the EcoQube.
• Official measurements: EcoQube Flex is designed for private radon monitoring. Legally required measurements (e.g. in workplaces) must be carried out by an authorized provider – ask us about passive Radtrak3® detectors.
