Air-Pressure Calibrator

The Micro-Cal Model 869 Ultralow-pressure documenting calibrator is designed for air-handling process in critical environments requiring high accuracy and low-pressure documenting calibration to certify pressure needs.

The machine performs calibration checks on sensors with accuracies as high as 0.00025-in. W.C. The battery-powered unit has a minimum of 8 working hours and gives a pressure reading accuracy close to 0.0001-in. W.C. with fast, stable, and repeatable pressure generation better than 0.0003-in. W.C. Recorded calibration times are as fast as 5 min/unit.
