ACE Pharma Clean Room Monitor AI-CRM1-1

KSh 44013KSh 45017

ACE Pharma Clean Room Monitor AI-CRM1-1 r is designed to measure the vital parameters of Temperature, Humidity, and Differential pressure in pharma cleanroom applications. The clean Room Monitor Model AI-CRM1-1 is designed for minimum cabling and easy flush mounting in modular wall panels or brick walls of the Clean Room.

Applications: Pharmaceutical Clean Rooms, Laminar Air Flow Cabinets, HVAC, Biosafety Cabinets, etc, measuring fan weight, blower weight, airspeed, heater draft, weight drop crosswise over hole plates, fluid levels in bubbler frameworks, weights in liquid frameworks, and filter resistance.


ACE Pharma Clean Room Monitor AI-CRM1-1 sensors for all 3 parameters are inbuilt inside for ease of use & installation. The combination humidity & temperature sensor is flush to the front stainless steel plate. The differential pressure is built-in with hose nipple connections at the rear for +ve & -ve pressure connections.
Features of ACE Pharma Clean Room Monitor AI-CRM1-1:

  • Integrated buzzer for parameter violation alert, individual LED for process violation visual alert & RS 485 Modbus Communication for easy integration to BMS/SCADA/EMS.
