EnviSmarts

Indoor and outdoor environmental monitoring with stand-alone monitors and online software

Rotem’s environmental monitoring system for nuclear power plants and other sensitive facilities, based on MediSmarts. Stand-alone environmental monitors for indoor and outdoor use connect via LAN, WLAN, 4G or radio, among others, to software that shows live readings as colour-coded points with history. The PM-33 and RP-33 monitors combine a sensitive NaI detector with the GM tubes of the TeleMeter and the RAM R-200 respectively.

Measurement range
PM-33 monitor: background to 15 mSv/h (1.5 R/h), the detector up to 10 µSv/h and then the TeleMeter’s GM tube; RP-33 monitor: background to 1 Sv/h (100 R/h) with the RAM R-200’s GM tubes from 10 µSv/h1
