The GEM (gas emissions monitor) detector can be used in nonhazardous commercial applications. The multipurpose, self-contained unit is available in one- or two-channel configurations accommodating accurate smart sensors. Features include integral and/or remote sensors, two 5-A dry contact relays, 4-20 mA linear output signal, and optional four-digit LED display. It includes new sensor CEF (Calibration Extending Firmware) that takes into account the aging of the sensors so that less frequent calibrations are acceptable in noncritical applications.
