Description
TPI 645 – Dual Input Differential Manometer

- Differential input with + 29 PSI range.
- 4 digit dual line with backlight
- Stabilizes display when measuring fluctuating pressures
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.
Features & Benefits
- 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.
