RADON MONITOR (ISL EM1100)
The ISL EM1100 Radon Monitor is a professional radon sensor for fixed installation in smart homes, radon monitoring or mounting in air handling units and extract air fans.
The sensor in the ISL EM1100 Radon Monitor is designed to provide instantaneous values, with good response times to changes in radon concentration. The sensor measures the level of radon in the air in Bq/m³ and produces an analogue output signal of 1-10 V, proportional to the radon concentration. The signal from the sensor can be connected to an ISL105J Analogue LoRaWAN transmitter to form a full system.
