Why clean room monitoring matters

Maintaining correct temperature, humidity and differential pressure is a continuous requirement in pharmaceutical and healthcare environments, not a one time setup.

  • Helps prevent contamination migration between zones
  • Supports product integrity and patient safety
  • Continuous monitoring with real time buzzer alerts
  • RS485 Modbus logging supports audit trails

Compliance & certification

Ace Instruments is manufactured under a certified quality system, with specific approvals for hazardous area and regulated applications where required.

  • ISO 9001:2015 certified manufacturing
  • CIMFR Dhanbad approval on flameproof scanners
  • Select monitors support USFDA 21 CFR Part 11
  • RS485 Modbus for BMS & SCADA interfacing
