Features

• This instrument can measure the air pressure of the single pipe, or differential pressure of two pipes.it is suitable for measuring of ventilation and air condition systems, and widely use for gas measurement, calibration, and any trouble shooting of any gas pressure systems.
• This instrument can measure differential pressure/positive pressure/negative pressure, and is equipped with a simple hose link device. No operation for 15 minutes, automatic shutdown.
• This digital manometer has Dual Input that can test / measure the differential gas pressure with its provided twin input probes.Max / minimum record function; Data save function, also has room temperature future.
• 12 Selectable Units of Measure – InH2O, Psi, Mbar, kPa, inHg, mmHg, ozin2, FtH2O, cmH2O, KGCM2, Bar,Pa.
• The gradient operation and reading are clear, and it is a good helper for HVAC technicians, operation and maintenance engineers and scientific researchers.
