Your cart is empty.The SDMN5 is a portable, rugged dual-port manometer designed especially for HVAC/R field service technicians. Measures gas pressure, static pressure and pressure differential. The SDMN5 includes a zero adjust button of the face of the meter, a rugged rubber boot, a magnet on the back for hanging the meter during service, and the Auto Power-Off (APO) function conserves battery life. The SDMN5 measures pressure between -60inWC and 60inWC (Inches of water column) and -150.0 to 150.0 mBar. The SDMN5 also measures P1 or P2 pressure readings and calculates the difference between P1 and P2. Take static pressure measurements using the resolution mode of 0.01inWC or 0.01mBar. Includes 3/16” to 5/16” adapter for measuring gas inlet and outlet pressures.

I needed a manometer to read manifold gas pressures on 4 stage gaspacs for commissing. This works beautifully and cuts down on time as my old one was a single port.

If you work in the HVAC field, then you know field piece is quality tools for the trade, this tool is mainly basic, but it still allows you to adjust the gas pressure and check the differianal pressures.

For the money this duel port Monometer is perfect. Durable, accurate and all of the above. Perfect for Hvac

While most HVAC Techs are highly skilled in diagnosing refrigeration problems by measuring refrigerant pressures with sophisticated gauges, few know much about troubleshooting airflow problems using a similar technique (sad but true). This instrument can be used to measure air pressures throughout a duct system to identify restrictions and blower and appurtenance problems, much the same as they routinely do for refrigerant tubing, compressors and appurtenances.Accomplished DIY-ers should be able to master the art of ductwork troubleshooting (DON'T ATTEMPT REFRIGERANT WORK AT HOME, FOLKS - ESPECIALLY WITH THIS INSTRUMENT).

Exactly what I needed, the static pressure probes in the picture were ordered separately

Works immaculately which it should given the price. Though it didn’t come with all the attachments I’d assume No complaints!

This fieldpiece works pretty good and fits into my tool pouch ok. the size could be smaller and there is no backlight which is inconvenient. The only thing this tool has going for it is the price. I had a Testo manometer before which is much smaller but a bigger price tag
