Single measurement type oxygen (O2) by diffusion method. Most gas detector manufacturers have a single line of oxygen, now users only need to choose the type of concentration display or alarm only, disposable or replaceable sensor for reuse.
This type of measuring oxygen gas in confined space, this time the machine needs to be integrated with a sample pump. Single-gas detector usually only measure diffusion, so if you want to measure the suction pump, you need to use a multi-gas detector. Users can optionally configure 4-gas detector with a suction pump and a separate O2 sensor, or simply use the 4-gas detector available in this application
