Draeger MicroTube Sulfur dioxide 0.05-5 ppm

With each set of MicroTubes, you can perform 10 individual tests. The substance-specific reactive layers and multiple pre-layers in the capillaries of the Draeger MicroTubes allow for selective gas testing. The various layers serve as a filter, for example. During testing, they filter out other substances that occur in the workplace so that only the target substance is indicated in the test result. This significantly reduces cross-sensitivities and lowers the number of false-positive test results and false alarms. The RFID tags applied to the Draeger MicroTubes contain all the calibration data that apply throughout their normal lifespan of one year. This eliminates the need for lengthy function tests and manual calibration. This reduces cost of ownership. MicroTubes are available for various hazardous substances and the number is constantly being increased.
