testo 312-3, the versatile manometer for the pre-test and main test on gas and water pipelines up to 87 psi. Pressure changes caused by changes in temperature during the measurement are balanced out by the temperature compensation function.

Features:

Load and tightness tests of gas pipes
Pressure testing of water pipes using air
Switchable measuring ranges with high resolution
Alarm indicator for undershooting of freely adjustable limit values
