Background:

Phosphine PH3 is an extremely poisonous gas with a wide range of divisions. For example, our common grain depots use phosphine as a fumigant gas to eliminate pests and diseases. In this way, there will be phosphine residues on site. Because on-site rapid detection of phosphine PH3 concentration is very necessary. So is there any way to quickly and accurately detect the concentration of phosphine PH3 in the field? Which phosphine sensor do I need?There are two methods, and their respective applicable scenarios will be different. We will introduce them separately below.

Method 1: Use a phosphine detector.

This is a portable phosphine detector, there are single type and compound type. The so-called single type means that the equipment can only detect phosphine.

Method 2: Use a phosphine detection tube.

If you need to detect the concentration of phosphine, then the above can not be achieved using the detector. Or, for economic reasons, the annual detection frequency is very low, then you can consider using phosphine detection tubes.

The above are about two methods for rapid detection of phosphine concentration in the field. By using the phosphine sensor to monitor the gas concentration in real time, the life, health and safety of the people on site are guaranteed.
