Using Phosphine Meters to Measure Phosphine Concentrations in the Air

Phosphine (PH3) is a flammable, toxic gas with an unpleasant garlic or rotting fish odor. It is absorbed in the lungs, leading to pulmonary edema, which can be fatal. It also acts on the central nervous system to cause symptoms like headache, nausea and tightness in the chest.

The PH3 phosphine meters in the air can be detected with a phosphine meter, or a PH3 monitor. This type of gas detector has sensors that detect the phosphine gas and send a signal to an alarm that sounds when it reaches dangerous levels. These meters are portable and can be used to measure phosphine concentrations in the air around grain bins, hoppers and silos.

Monitoring Phosphine Levels: The Importance of Phosphine Meters”

When using phosphine, it is important to follow the instructions on the fumigant label and the applicator’s manual for a successful fumigation. This includes preparing a fumigant plan, storing the aluminum phosphide pellets or tablets properly and keeping a record of the amount of PH3 gas used in a structure.

During the fumigation, it is also important to make sure that aeration has occurred and the structure is safe for re-entry. A PH3 meter can help you do this by letting you know the phosphine concentration in the air so that you can determine if it is safe to enter. These meters have tubes that change color as they are exposed to PH3 and have a pump with an extension hose so that the air can be sampled from outside.
