Frequently Asked Questions

How to calibrate pressure gauges?

Selected pressure gauges have to be connected to calibration devices. The device applies maximum pressure to the pressure gauge then the pressure is bled completely and the pointer returns to zero. This process calibrates the pressure gauge.

What are bi-metallic thermometers used for?

These thermometers are ideal for monitoring ovens, air conditioners, heaters, refineries and hot wires.
