Schutz Messtechnik PS 403 Gas Detector

Item number: 202.779

With the Schütz PS 103 to 403 test stations, you can, among other things, perform a sensitivity test (10 ppm) of the gas concentration meter to test the surface before starting work and after when interrupting important work (DVGW G 465-4). You can check the display accuracy of the gas detector easily by connecting different compressed air cartridges to the respective test gas (1 vol. % – 2.2 vol. % – 100 vol.%) Go to the test station. However, if you continuously use a variety of gases, we recommend purchasing one of the larger 203 or 403 test stations.

All gases can be connected in a 1-liter aluminum pressurized air box. The remaining tank pressure is always displayed. If a larger volume of air is required, a steel pressurized gas tank can be connected via an adapter and a pressure reducer. With flow meter.
