This portable gas detector comes in two versions: Microtector III without a pump and Polytector III with an integrated suction pump. Importance has been placed on reducing the size and weight of the unit to provide a lighter overall experience for the user when carrying protective equipment. The display is slightly inclined forward and can be rotated using a simple key combination to provide comfortable readability from any holding or carrying position. The unit warns of gas hazards with a 103 dB horn. In addition, the display provides clear information about the current hazard situation using the traffic light colours red, yellow and green.
