Weighing and measuring instruments are essential tools for gas cylinder and fire extinguisher maintenance: accurate checking of the filling quantity, weighing before and after refurbishment, checking contents all require precise measurement. PWENT offers a complete range of industrial scales, dynamometers and pressure gauges.

The role of accurate measurement in maintenance
Accurate weight measurement is critical at every step of gas cylinder maintenance. Checking the stored charge before refurbishment: if the difference between the marked tare weight of the cylinder and the measured weight is significant, this indicates a change in content. Weighing after filling: the exact amount marked should be in the cylinder - overfilling is dangerous, underfilling is uneconomical. Annual inspection of fire extinguishers: weight checks of extinguishers and CO2 extinguishers are mandatory as part of official maintenance.
