Description

The BT-645 Portable Dust Monitor has been designed to continuously measure and record particulate information for indoor work place and public place environments

  • Optical Sensor 
    A laser optical sensor is used to detect and measure particulate concentrations up to 100 milligrams per cubic meter. The continuous flow optical sensor is combined with purge air to ensure accurate measurements in adverse environments.
  • Rugged Design 
    The optical sensor, matched electronics and backlit display, are enclosed in a rugged metal enclosure to protect the instrument from normal daily use.
  • Data Storage 
    The eternal datalogger will store over 5,000 samples. Sample history events can be viewed on the display or downloaded to a computer using Coment software.
  • Battery Operation 
    The internal battery pack provides over 10 hours of continuous operation. Battery recharge time is approximately 2.5 hours.
  • Optional Inlets 
    The standard unit is supplied with a TSP inlet. Optional sampling inlets are available for PM2.5, PM4 and PM10.

Applications:

    • Public and Workplace Monitoring
    • Industrial/Occupational Hygiene
    • Indoor Air Quality
