Our ES-642 measures particulate concentration using a highly sensitive forward scatter laser nephelometer, which has a measurement range of 0 to 100 mg/cubic meter (0 to 100,000 μg/cubic meter). As supplied, the ES-642 provides TSP particulate monitoring. Optional sharp-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. Serial outputs are MODBUS and basic ASCII via RS-232 or RS-485. Analog outputs include both 0-10 volts and 4-20 mA.
