Current radon concentration
short-term (0,5 hour running average from RaA)
long-term (24 hours running average from RaA + RaC)
Dimension
Ø 80 x 175 mm
Waterproof
IP67 (only for electronics)
Operating conditions
Temperature: -10 ° C to +40 ° C
Recommended relative humidity: 10% - 75%
Maximum working relative humidity: 0% - 99%
* Increased humidity reduces the life of a charged battery.
* There must be no condensation of water in the chamber -
erroneous results
Detector life
50-100 million pulses;
that means at an average concentration of 1000 Bq / m3 -> 12

Operating Instructions
Switching on and off:
The probe measures radon concentration autonomously and communicates in wireless network only if
the switch is in position „on“. The switching on is signalized by LED diode „STAT“ according chart below.
If the switch is in position „off“ the probe doesn´t measure radon concentration and doesn´t
communicate in wireless network. In switching off mode the probe only keeps running real time for correct
date and time of records in case of switch it on again. By switching off the probe doesn´t lose previous
records of measurement. The switching on is signalized by LED diode „STAT“ according chart below.
It is possible to download data from probe over USB in both position of switch.
