Monitor Measures Dust Hazards in Real Time

Casella’s CEL-712 Microdust Pro monitor is a small, rugged, handheld instrument that measures concentrations of inhalable dust in real time for display on its high-contrast color LCD. With a wide detection range (0.001 to 25,000 mg/m3) and full data logging, it can be used independently to measure material processes or to capture release events such as bag breaks, or can be paired with a cyclone, filter cassette, and sample pump for size-selective or gravimetric monitoring. Using a laser diode based light-scattering sensor, the battery-powered CEL-712 accepts material-specific correction factors and is easily field calibrated with its optical reference cell (included). The CEL-712 also provides proportional output voltage and data stream interfaces.
