The Portable Low Pressure Calibrator series extends the general unit pressure capability down to 1 in H2O.
Setting the standard for low pressure calibrators The Portable Low Pressure Calibrator series extends the general unit pressure capability down to 1 in H2O. The LP series combines the easy to use Task menu and electrical measure/source capability of the successful LP series with the low-pressure sensor. This makes the low pressure series an ideal calibrator for commissioning, maintaining and calibrating low-pressure transmitters, transducers, gauges, indicators and switches.
At low differential pressures, even connecting the device under test can induce significant pressure. To compensate for this, an "auto zero" facility is provided which uses an internal solenoid valve to equalize the differential pressure prior to zero correction
Applications The unit is the ideal reference standard to reduce instrument maintenance time and errors for quality systems compliance.
Dedicated tasks for transmitters, transducers, gauges, micro manometers and switches, simplify commissioning, maintenance and calibration.
The unit is designed to calibrate-in-place for very low-pressure sensors.
