PresSura Cleanroom Monitors 8630-CRM


Product Details

This unit has been discontinued as of December 15, 2016.

The PresSura™ Cleanroom Pressure Monitor Model 8630-CRM is designed to measure the actual room pressure differential in clean rooms. It is easily configured to accept different pressure transducer ranges, allowing it to be used in almost any cleanroom. If the pressure differential is too great, too small, or the wrong direction, the 8630-CRM will activate audible and visual alarms. It can also monitor the supply air volume, ensuring proper ventilation of the clean room. The 8630-CRM features adjustable alarm delays to avoid nuisance alarms.

The 8630-CRM easily integrates to the building management system using a low alarm relay, an analog output of the measured pressure differential, or digital communications. The 8630-CRM supports the open MODBUS protocol.
