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.

The robust Dräger Pac® 6500 is your reliable companion under tough conditions. The personal single-gas detection device measures CO, H2S, SO2 or O2 quickly and precisely. Measured data can easily be transmitted into the Dräger Gas Detection Connect system via Bluetooth®. Quick sensor response times and a powerful battery also ensure safety.

The Dräger Pac® 8500 single-gas detection device is a reliable and precise instrument even under the toughest of conditions. Measured data can easily be transmitted into the Dräger Gas Detection Connect system via Bluetooth®. The device can be equipped with a hydrogen-compensated CO sensor or a Dräger dual sensor. This gives you the option of measuring two gases at once: H2S with CO, H2S with O2 or O2 with CO.

The Dräger X-am® 2500 was especially developed for use as personal protection. The 1 to 4 gas detector reliably detects combustible gases and vapours, as well as O2, CO, H2S, NO2 and SO2. Reliable and fully mature measuring technology, durable sensors and easy handling ensure a high degree of safety with extremely low operating costs.

• 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.
  
  
  

• The PS200 Series combines quality, ruggedness and advanced technology in a user friendly, portable gas monitor. It is compact, lightweight, water resistant, extremely robust, and is certified to multiple international and regional standards. 
• The PS200 can measure any combination of LEL, O2, CO and H2S making it suitable for a wide range of personal monitoring and confined space applications. 
• In addition to extensive datalogging capabilities, the PS200 is available with an optional internal pump and an extensive range of accessories to meet a wide variety of user applications. 
• Importantly, the PS200 has been designed to enable easier user maintenance which includes a fully automatic calibration station to simplify product compliance.
