WatchGas PDM NH₃

The WatchGas PDM NH₃ is a compact, maintenance-free disposable gas detector for reliable detection of ammonia (NH₃) in the ambient air. It has been specially developed for use in refrigeration systems, fertiliser production, wastewater technology, the food industry and chemical plants where ammonia may be released.

Once activated, the device operates for up to two years without maintenance, without the need for battery replacement or calibration. The easy-to-read display clearly shows the current measured values, the device status and the remaining operating time.

If the preset limit values are exceeded, the WatchGas PDM NH₃ reliably warns the user via visual signals, an acoustic alarm with a minimum volume of 95 dB and vibration, ensuring that warnings are clearly heard even in noisy or confusing working environments. The robust housing with protection class IP67 is dustproof and protected against temporary submersion.

Thanks to its compact design and integrated clip, the gas detector can be securely attached to clothing or a belt. The scope of delivery includes the WatchGas PDM NH₃ gas detector, a calibration adapter and the user manual, so that the device is ready for immediate use.
