Cleanroom Pressure, Temperature & Humidity Monitoring

Cleanrooms must maintain tight control of differential pressure, temperature and relative humidity to protect product quality and sterility. Any drift can bring a room out of its ISO 14644 classification, trigger EU GMP Annex 1 non-conformities or compromise audits.

Regulators now expect continuous, tamper-evident environmental data with electronic signatures and audit trails per FDA 21 CFR Part 11. The bundle below meets those requirements while integrating easily with cloud, SCADA or BMS systems.

RHT Climate, NP785 And LogBox WiFi

The RHT Climate transmitter measures temperature and humidity, while the NP785 captures ultra-low differential pressure to verify cleanroom cascades. Both 4-20 mA signals wire into the LogBox Wi-Fi, an FDA 21 CFR Part 11-compliant data logger that buffers more than 140 k readings with secure audit trails and electronic signatures.

LogBox publishes live data and alarms over MQTT to cloud brokers or Modbus TCP to SCADA/BMS/EMS platforms, simplifying integration with existing infrastructure. The solution helps demonstrate continuous environmental control required by ISO 14644 and EU GMP Annex 1 while satisfying modern data-integrity mandates.
