The ES-642 Remote Dust Monitor is an industrial air-quality sensor designed to provide accurate measurements of particle concentration in both indoor and outdoor environments. The unit is supplied in a rugged weatherproof enclosure. It includes an LCD display to provide information about particulate concentration, flow rate, instrument status and power. The electronics and optical system are protected from moisture by a built in intake heater that is humidity level controlled. The heater power is regulated to maintain a minimum humidity level. Additional features include a purge air system and an automatic zero calibration routine. The sensor can be wall mounted or installed on a vertical mast up to 3 inch in diameter.


  • Designed to provide accurate information on particle concentration and operate continuously in adverse environments.

  • Special features such as the purge air system and automatic zero calibration enable the monitor to operate 24/7.

  • A sheath air system isolates the aerosol in the chamber to keep the optics clean for long term reliability and low maintenance.

  • LCD Display provided information on operation including: power, heater power, flow operation, status and particulate concentration.
