Best Manometer for the price!
Purchased a cheaper more cost effective manometer at first, which I should have just purchased this one from the start. Seems to be very accurate, and easy to read . Definitely cannot go wrong with Fieldpiece , if you’re looking into purchasing a manometer, don’t waste your time with other cheaper brands, this is worth its weight in gold.

A whole lot cheaper than hiring a tech
Worked well for me, made it easy to test air flow thru different filters. Allowed me to determine the highest MERV ratingI could use without stressing the blower in my HVAC and shortening its lifespan. A little expensive for something I won't use often but a whole lot cheaper than hiring a tech

Great price for quality
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.

A Must For Troubleshooting HVAC Airflow Problems
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).
