Heise® Model ST-2H Dual Display LCD Digital Pressure Indicators


   The Heise® ST-2H is a bench or panel mounted precision multi-function indicator that displays two simultaneous measurements of pressure, temperature, mA or volts. The unit can also measure differential pressure across two modules. The "Quick Select™" pressure and temperature modules are easily interchangeable and can also be used in the Heise® PTE-1 handheld calibrator. Measurements can be stored in the ST-2H memory for future upload to a computer.

   The ST-2H is the ideal bench top unit for calibration of pressure gauges, transducers, transmitters, switches and relief valves.
