The Heise handheld precision calibrator offers practical, state-of-the-art features specifically designed to meet modern line-test application requirements. With its unique modular sensor system, the PTE-1 can be easily configured to measure ranges from 0 to 0.25 H2O to 0 to 10,000 psi. The interface modules add temperature measurement with RTDs or thermocouples, while on-board jacks provide measurement of voltage and current. Two sensor bays and a twin LCD provide simultaneous display of any two measurements. Application specific features support common calibration tasks such as setting pressure switches and relief valves and calibrating pressure transducers.
