Introduction
Congratulations on your purchase of the Extech 406800 Differential Pressure Manometer.
This device measures Gauge/Differential Pressure from 0 to 138.3 inH2O (inches of water).
It features 11 selectable units of measure: inH2O, psi, bar, mbar, kPa, inHg, mmHg, oz/in2,
ftH2O, cmH2O, kg/cm2. Additional features include: Data Hold, Auto Power Off disabled,
and an RS-232 for capturing readings to a PC using optional software (407752). Careful
use of this meter will provide years of reliable service.
