Review on PerfectPrime Professional Manometer Differential ±83 02InH2O Test, Measure & Inspect by Bill Schmits

This differential pressure manometer is an exceptional tool for measuring airflow in HVAC systems. Its accuracy and precision HAVE been impressive for my industrial and scientific work.After i put it to the test, I found it easy to handle and operate. The backlit LCD display and auto shut-off feature are quite useful in low-light environments. However, the included manual could be more comprehensive to enhance user experience. Overall a valuable addition to any airflow and air quality testing toolkit..
