Heise Model PTE-1 Dual Display LCD Handheld Digital Calibrator Available

The Heise PTE-1 has set a new standard for precision pressure test and measurement instrumentation. With the unique Quick Select® modular sensor system, the PTE-1 can be easily configured to measure ranges from 0-.25” H2O to 0-10,000 psi.

Quick Select® interface modules add temperature measurement with RTDs or thermocouples, while on-board jacks provide measurement of voltage and current (mA). 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. With the datalogging option, calibration results can be stored for subsequent upload to a PC.
Field tested and proven reliable, the Heise® PTE-1 is the popular choice for portable pressure calibration around the world.

For benchtop applications, the model ST-2H is similarly equipped and shares the same Quick Select® modules.
