TPI 645NPT Dual Input Differential Manometer with Stainless Steel Compression Fittings
Dual Differential Input Manometer with ± 29 psi range and 0.1 psi resolution. Seven units of pressure: inH2O, mbar, KPa, PSI, mH2O, mmHg, inHg, Auto power off, Record/Min/Max, Backlight display, Zero function, Trim mode to stabilize readings.
APPLICATIONS Check for proper pressure in pneumatic systems Check supply gas pressures Check for proper pressures in clean rooms Check industrial HVAC systems Check operation of industrial pressure switches Same as 645 (42500-24) but with 1/4" NPT(F) to 1/4" barb fittings, 2 stainless steel compression fittings, carrying case, and protective boot Measure pressure of air and natural gas 655L measures pressure of non-corrosive water/liquid applications Rugged extruded aluminum housing Measure positive differential pressure Push button zero for altitude correction Seven selectable units of measure to choose from: mmHg, inHg, kPa, mBar, PSI, inH20, and mmH20 Backlight with auto shut off after 10 seconds Auto shut off after 30 minutes (except REC mode) to save battery life Easy-to-read LCD Record function stores maximum and minimum readings 3-year limited warranty Data hold to freeze reading on LCD
Features & Benefils
- Auto ranging - Provides high resolution & accuracy at low pressures where it is needed
- Auto Power Off - Powers off after 30 minutes to conserve battery life.
- Trim Mode - Smoothing function to stabilize erratic readings. It displays the average value of 4 values previously measured.
- Zero function - Provides immediate push-button zeroing for Speed and accuracy.
- Record Max/Min - Enables long term testing of pressure systems for leaks
- Hold - Enables the user to freeze the display reading, when working in cramped working conditions, when the display is not visible.
- Units - Change the display value in anyone of the following engineering units. kPa, PSI, inHg, mmHg, inH20, mH20 and mbar.
