ASYS dBELL 110 IAQ Monitor

A flexible tool for conducting airborne hazard studies and assessing mitigation strategies, the ASYS dBELL 110 IIoT Multi-tool can be deployed as a personal exposure dosemeter, a handheld instrument or a remote monitor compatible with the ASYS dBELL IIoT ecosystem.

At the heart of the dBELL 110 are calibrated, traceable PID and Optical Particle sensors capable of measuring TVOC and PM parameters required for workplace air quality and personal exposure assessments, TVOC(ppm), PM2.5, PM4 (respirable) and PM10.

Usage modes:

  • Personal exposure dosemeter: Shoulder mounted for general exposure or task specific assessments where airborne hazards are likely, for example welding, machining, degreasing, cleaning etc.
  • Handheld instrument: Conducting spot checks around the workplace environment.
  • Remote monitor: For longer term process studies.

The dBELL 110 automatically connects to the ASYS dBELL 100 IIoT integrated gateway and area monitor via LoRaWAN®, a sub-g wireless technology ideally suited for long range and minimal power consumption.
