The Clean Room Panel CRP5, which is equipped with a membrane sensor for differential pressure measurement, is a top quality device. Validated according to GMP guidelines, and with its thoughtful design, the CRP5 is optimised for applications in laboratories and clean rooms.



LOW COST Datalogger for temperature.Compact, reliable and affordable. Validated according to GMP guidelines, and with its thoughtful design, the CRP5 is optimised for applications in laboratories and clean rooms. Optical buttons, and the magnetically mounted, removable HC2-CRP humidity and temperature probe allow for efficient and effective cleaning. Up to 6 measured values and messages can be displayed via the graphic colour display. The colours of the display can be set individually Alarms such as faults, limit values exceeded or warnings are highlighted on the CRP5 display, and can also be transmitted digitally via MODBUS, Ethernet or relays. Thanks to its analogue and digital communication capabilities, the CRP5 can be easily integrated into any surveillance system. Due to its wide range of functions, the CRP5 can be perfectly configured for any application. The CRP5 stands out on the market with its sturdy glass front and removable humidity sensor.

Applications Clean Room Panel CRP5

The CRP5 clean-room panel is the obvious choice wherever a high degree of cleanliness is vital, as well as accurate measurements of differential pressure, humidity and temperature. The CRP5 is mainly used in clean rooms in hospitals, in the pharmaceutical, electronics and food industries, and wherever small pressure variations need to be monitored. The CRP5’s comprehensive functional capabilities provide solutions for many measurement and control tasks.
