For monitoring only one hazardous gas, single gas monitors are the right solution. You can easily carry the single gas monitors on your working clothes. Depending on the frequency of operations, you can choose of disposable and reusable single gas monitor devices. Disposable detectors measure standard gases which can also be detected by our reusable CO, H2S, SO2 or O2 detectors. Monitoring special or reactive gases is also possible, e.g. with an O3 detector. Furthermore, we offer you single gas detectors with hydrogen-compensated CO sensor or even a dual sensor measuring two gases at once.
