Fire hose testing laboratory

2022-12-06

A fire hose is a hose used to transport flame-retardant liquids such as high-pressure water or foam. It is an important fire-fighting equipment in fire safety facilities, so it has always been a link that our fire department attaches great importance to.

Both ends of the fire hose have metal connectors that can be connected to another hose to extend the distance or to a nozzle to increase the pressure of the liquid spray.

Its quality and performance can directly affect the speed and efficiency of firefighters in fire fighting and disaster relief. Then this indispensable fire-fighting equipment must have relevant fire hose laboratory and fire hose inspection equipment to test the performance and quality of fire hose. Next, Zonsky Instrument will introduce several common Testing Equipments in the fire hose laboratory.
