The WatchGas PDM disposable single-gas detector is easy to wear thanks to its strong metal crocodile clip and can be worn on a collar, a belt or even a safety helmet. Compact and lightweight with a weight going from 93g up to 104g depending on the sensor, this portable single-gas detector is IP67 certified against dusts and water. Its housing is made of polycarbonate and rubber, making the WatchGas PDM a rugged disposable gas detector that can be used even in the harshest environments.

Once the target gas concentrations in ambient air exceeds alarm thresholds, the powerful 95dB audiovisual alarm of the WatchGas PDM single-gas detector will activate to alert people working in the hazardous area.

Thanks to its optional docking station, it is even easier to calibrate and bump test the WatchGas PDM disposable gas monitor. This docking station can hold up to 4 WatchGas PDM single-gas devices at once for faster testing of several instruments. It can also manage the detectors settings, test parameters and can be used to transfer data stored for further analysis. Moreover, as it can be easily carried and used with rechargeable batteries, the WDS docking station is ideal for in-vehicle or multi-site use.
