Key Features
Built-in pump and Ethernet integration
The integrated pump supports a self-contained fixed monitoring point, while Ethernet with Modbus/TCP connects the sensor to a monitoring computer or plant network.
Compact fixed-point format — low-intrusion installation
The compact format allows installation in ceiling tiles, wall panels and HVAC supply plenums without visible intrusion into the cleanroom environment — reducing potential contamination sources from monitoring equipment and maintaining cleanroom aesthetic.
ISO 21501-4 calibrated sensor
Factory-calibrated to ISO 21501-4 with manufacturer calibration certificate — satisfying calibrated instrument documentation requirements for ISO 14644-2 cleanroom monitoring programmes.
