The PDM+ is a personal sustainable single gas detector designed to detect Oxygen deficiency and the presence of toxic gas in the ambient environment. The PDM+ is sustainable and has TWA and STEL available, hence its battery and sensor can be replaced. When turned on, PDM+ continuously monitors ambient air for the presence of a specific gas and alerts the user to potentially unsafe exposure with LED, vibrating, and audible alarms if the gas concentration exceeds alarm set points. After use, the instrument can be turned off.

• Calibrating the monitor means exposing it to a known concentration of calibration gas or test gas for a specific amount of time. 
• This reading becomes the gas detector's reference point for future readings. 
• Repeat this process each month to ensure accurate readings.
•  Regular calibration is essential in order to maintain reliable performance of most gas detectors.
•  During calibration, thorough testing is also carried out to ensure that the gas detector remains sufficiently sensitive and responsive to the exposure of gas required.
