Industrial Grade Pressure Calibrator Module covers pressure calibrations from 0 to 1 in H20 to 10,000 PSI. The Calibrator has one pressure fitting and measure the pressure with respect to atmospheric pressure. The Calibrator has digital communication to calibrators, no analogue losses or errors. The Calibrator has two pressure fittings and measures the difference between the applied pressures on the high fitting versus the low fitting. The Industrial Grade Pressure Calibrator Module has temperature compensated ranging from 0 ° c to 50 ° c.
