Presentation

The Met One Instruments ES-642 Remote Dust Monitor is an industrial air quality sensor designed to provide real-time particle concentration measurements in indoor and outdoor environments.

The ES-642 device measures particle concentration using a highly sensitive direct scatter laser nephelometer, which has a measuring range of 0 to 100 mg / cubic meter (0 to 100,000 μg / cubic meter) . As supplied, the ES-642 provides monitoring for TSP particles. Optional clean cut cyclones are available for PM1, PM2.5 or PM10.

The ES-642's serial and analog outputs support a wide variety of data collection systems. The serial outputs are MODBUS and basic ASCII via RS-232 or RS-485. Analog outputs include both 0-10 volts and 4-20 mA
