ESM-01 Detectors

The construction of the various ESM-01 detectors is similar. Each of the ESM-01 detectors has a

different replaceable plug-in sensor that protrudes through the detector housing cap. Although

ESM-01 detectors look the same except for the plug-in detector, the detector housing which

includes the detector socket and conditioning circuitry is specific to a sensor type. For example, a

detector housing from a Cl

detector cannot be used with an NH

detector. One of the two detector

wires is color coded for each specific detector type. The ESM-01 detectors include a removable

splashguard that screws onto the detector housing cap. When it is necessary to apply gas to an

ESM-01 detector, remove the splashguard to allow access to the sensor that protrudes through the

detector housing cap. You can then push the appropriate ESM-01 calibration cup onto the sensor.
