Clean Rooom Scanner with RTC


The Environment Monitor is designed to measure the vital parameters of Temperature, Humidity, Differential Pressure & Real Time synchronized Clock in a single instrument in clean room area applications. The instrument is housed in an aesthetic M.S. body with stainless steel enclosure.

The Model AI-CRM4A is designed for minimum cabling & easy mounting in clean room areas & accepts 4 Analog Inputs , range programmable from front keys for 4-20mA Zero & Span settings. Each of the analog inputs is range programmable, temperature & humidity being range programmable between -99 to +999, the differential pressure input is programmable from 0 to 99 Pascals/mm.W.C. & the Channel Number is programmable from 0 to 9. The analog inputs can accommodate any front end transmitters from some of the world s most popular ones from Siemens, Honeywell, Sauter Race, Greystone , Dwyer, etc.
