Extinguisher Pressure Gauge

The extinguisher pressure gauge made in China is divided into three sections:

The first section is the red area, and the pointer points to the red area, which means that the pressure of the dry powder in the fire extinguisher is too low to be ejected, and it has failed. At this time, you should go to a regular fire equipment store to refill the dry powder.

The second segment (narrower) is the green area, and the pointer points to this area, indicating that the pressure is normal and can be used normally.

The third yellow area indicates that the pressure of the dry powder in the fire extinguisher is too large and dry powder can be sprayed out. But there is a risk of explosion and explosion. The extinguisher pressure gauge in this state is best to be refilled with dry powder at a regular fire equipment store.The yellow grid area is a dangerous area for inflatable fire extinguishers used by manufacturers during the production or maintenance process. Generally, we will charge them in the green grid area. If the pointer is in the yellow grid area, it means that the pressure is too high, as mentioned above. Dangerous, but it does not mean that it is invalid when used!
