DPI 610/615 LP Series - Portable Low Pressure Calibrators

DPI 610/615 LP Series - Portable Low Pressure Calibrators


The DPI 610/615 low pressure calibrator versions enable the end user to calibrate draft range instrumentation in the field.


This feature minimizes the effects of moving the unit under test and any offsets that may occur. The test data can then be stored for uploading to your computer at a more convenient time.
