WatchGas PDM+ Gas Detector

PDM+ is a gas detector that continuously measures concentrations to detect a lack of oxygen in the environment and the presence of toxic gases.

PDM+ is a gas detector that continuously measures concentrations to detect the lack of oxygen and the presence of toxic gases in the environment. PDM+ allows for continuous concentration measurement by replacing the battery and sensor. When powered on, PDM+ continuously monitors whether the target gas is present in the air and warns the user with alarms through LED lights, vibrations, and sounds if there is a possibility of entering a dangerous state. Additionally, it can be used for up to three years by turning off the power after use. PDM+ is easy to operate, and it features a strong metal clip on the back of the unit, allowing it to be secured to shirts, belts, helmets, and more. The PDM+ gas detector is compatible with the Watch Docking Station and WatchGas IR Link. Both devices have the capability to download data from the PDM+ single-component gas detector. The latest 30 historical records are stored in the internal logger of the unit. Oxygen, carbon monoxide, hydrogen sulfide, hydrogen, sulfur dioxide, ammonia, hydrogen peroxide, nitrogen dioxide.
