The Crowcon APM145 Differential Manometer is capable of measuring pressure from -39.99mbar to 130mbar over two separate ranges (-39.99mbar to 19.99mbar; 20mbar to 130mbar). It has an accuracy of ±2% and a maximum resolution of 0.01mbar.
The pressure meter is capable of measuring differential pressure, working pressure, operating pressure and flue draught pressure as well as performing let/by and tightness tests. The user can set their own PASS/FAIL limits and durations for tightness tests.
Pressure readings are shown in a range of different units (mbar, PSI, mmHg, mmH2O, inH2O, hPa, Pa, kPa) on the Crowcon APM145’s clear digital screen. It has backlighting for use in poor lighting conditions and an internal memory for storing test results.
