Fieldpiece SDMN5 Dual-Port Manometer — Gas Pressure, Static Pressure & Differential
The Fieldpiece SDMN5 is a portable dual-port manometer designed for HVAC/R field service technicians who need to measure gas pressure, static pressure, and pressure differential on the job. With a range of -60 to +60 inches water column (inWC) and a static pressure resolution of 0.01 inWC, the SDMN5 covers the pressure measurements HVAC/R technicians encounter daily — from gas inlet and outlet pressure checks to static pressure across blowers and filters.
The SDMN5 includes standard 3/16" fittings and adapters for 5/16" ports, a magnetic hanger for hands-free use, a zero adjust button, and auto power-off to conserve battery life.
Gas appliance pressure testing and servicing requires appropriate trade qualifications and licensing. Confirm licensing and compliance requirements with the relevant authority in your state or territory before undertaking gas-related work. Confirm all specifications against the Fieldpiece SDMN5 datasheet.

- 3/16" to 5/16" adapter for gas inlet and outlet pressure measurement
SDMN5 vs SDMN6 — Which Manometer?
- SDMN5 ($356.95): Dual-port manometer for gas pressure, static pressure, and differential measurement. No internal pump.
- SDMN6 ($683.95): Adds an internal pump for pressure switch testing and calibration. Suited to technicians who need to test and calibrate furnace pressure switches without carrying a separate pump.
Best For
- HVAC/R technicians checking gas inlet and outlet pressures on appliances and regulators
- Static pressure measurement across blowers, filters, coils, and ductwork
- Differential pressure measurement between two points
- Technicians who need a rugged, portable manometer for everyday field service
Check Before Ordering
- Gas appliance pressure testing requires appropriate trade qualifications — confirm licensing requirements in your state or territory
- Confirm fitting compatibility with your specific appliance service ports — 3/16" and 5/16" adapters included
- For pressure switch testing, see the SDMN6 with internal pump
- Confirm warranty terms with HVAC Trade Supply at time of purchase
Frequently Asked Questions
What is the difference between the SDMN5 and SDMN6?
