Rolls up for easy storage and transport

Over pressure safety traps to prevent loss of fluid due to over range pressures or surges in pressure

RoHS Compliant

The SDMN6 dual-port manometer measures gas and static pressure and also accurately tests pressure switches by simulating a draft with an internal pump

A pressure switch is a safety device that prevents the furnace from running in an unsafe manner

The SDMN6 tests the pressure switch to determine if it is working properly, or if it is starting to fail which can cause the furnace to run in an unsafe manner

Plus, with the sdmn6 you can easily calibrate any adjustable pressure switch to manufacturers' specification, so there's no need to carry a large variety of pressure switches on your truck

The dual port manometer has the ranges to measure gas pressure and the resolution needed to measure static pressure

Ideal for HVACs field service technicians, the SDMN6 can determine if the gas pressure coming into the house or out of the regulator are correct

The SDMN6 also has a zero adjust to zero out the meter in different ambient pressures

It has a hold button to hold the currently displayed reading

the auto-power-off function conserves battery life, but can be disabled if desired
