Smart Radon Sensor

SARAD's Smart Radon Sensor is a high-precision electronic radon measuring device specially designed for continuous measurement of radon activity concentrations in various environments. It is ideal for use in homes, workplaces, waterworks, nuclear power plants and other areas where radon monitoring is required.

Key features:

Very high sensitivity: The sensor offers high accuracy and reliability in measuring radon concentrations.
Immune to environmental influences: The sensor is insensitive to changes in temperature and humidity, external radiation, and mechanical shocks and vibrations.
Versatile interfaces: Equipped with an RS485 network interface (MODBUS RTU or Sarad protocol) and an analogue output for integration into existing control systems.
Integrated switching output: For controlling ventilation systems based on the measured radon levels.
Optional wireless interfaces: ZigBee or Wi-Fi for connecting to host systems.
Battery backup: Two AAA batteries for data backup during power outages.
Additional sensors: Equipped with temperature and humidity sensors as standard; CO₂ and pressure measurement optionally available.
DAkkS-accredited calibration: Calibrated according to DIN EN ISO/IEC 17025:2018.
