The WatchGas PDM is a reliable single gas detector that offers you unrivalled value. The PDM
single gas detector is your everyday monitor for hazardous environments, thanks to its high reliability and ease of use. The device can be fitted with sensors for oxygen (O2), hydrogen sulphide (H2S), carbon monoxide (CO), sulphur dioxide (SO2), hydrogen (H2), ammonia (NH3) or nitrogen dioxide (NO2). The PDM is the most cost-effective way to guarantee safety. It runs maintenance-free for up to two years (24 months). You switch the device on and it works continuously until the 24 months have elapsed. In the meantime there is no need to charge the device or replace the sensor. That means great reliability and no downtime.
The WatchGas PDM is a lightweight model in a striking orange colour. The back of the device has a strong metal crocodile clip to attach the monitor to overalls, a belt or a helmet. The
gas detector can be used in combination with the WatchGas Docking Station for 1 or 4 devices.
Both docks offer the option of downloading the measurement data from the PDM monitor.
The 30 most recent events are stored and can be read out via a PC. If required, you can also calibrate or bump test the WatchGas PDM without a docking station. The large PDM docking station automatically calibrates four devices at the same time (up to 12 devices per minute), which reduces downtime and gas consumption.
