SDMN5 Standalone Manometer Offers Precision Measurement of Gas and Static Pressure

BREA, Calif., February 16, 2006 -- Fieldpiece Instruments, a leading provider of hand-held instruments for field service HVACR technicians, has introduced model SDMN5 Dual Port Manometer. The SDMN5 is a standalone low-cost solution for gas or static pressure measurement. The SDMN5 is the latest development in the series of standalone products Fieldpiece Instruments provides for the field service tech, most of which are also offered as accessory heads.

The Dual Port Manometer has the ranges to measure gas pressure and the resolution needed to measure static pressure. Ideal for HVACR field service technicians, the SDMN5 can determine if the gas pressure coming into the house or out of the regulator are OK. The SDMN5 measures gas pressure up to 60" water column (WC) with a resolution of 0.1" WC. In addition, the unit measures both positive and negative pressure, which is used for measurement on vacuum control lines. The unit will take differential pressure readings and display the difference between P1 and P2 at all times in the lower right corner of the easy-to-read LCD. Four different measurement scales can be used: inches of water column, millimeters of water column, mBar, and PSI.

The SDMN5 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.
In the static pressure mode, the unit can measure up to 2"WC with resolution to 0.010"WC, which enables a technician to measure small differences in air (or static) pressure.

“Now any technician can afford to conveniently measure static pressure because he can do it with his gas pressure measuring instrument,” says Rey Harju of Fieldpiece.

The SDMN5 Dual Port Manometer is priced at $139. The SDMN5 is housed in a rugged rubber boot and includes a clear front case, hoses, and a magnetic hanger for hands-free operation.
