Ambi100 Remote Dust Monitor

The Ambi100 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 particle 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 instrument measures particulate concentration using a highly sensitive forward scatter laser nephelometer, having a measurement range of 0 to 100 mg/cubic meter or 0 to 100,000 µg/cubic meter. Optional sharp-cut cyclones are used to set the measurement level of the Ambi100. As supplied, it provides particulate monitoring for TSP. With the addition of the sharp-cut cyclone, it can be set for particulate smaller than PM10 or smaller than PM2.5 or PM1. The accuracy of the instrument is ± 5% based on a traceable PSL 0.6 micron reference standard.

  •  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 to 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 provides information on operation including: power, heater power, flow operation, status, and particulate concentration

The sensor can be wall-mounted or installed on a vertical mast up to 3 in. in diameter.

The Ambi100 is supplied with a 10 ft. cable and connector for power (15 to 40 VDC) and signal output.
