Description
The Keller HPX-700BAR High Pressure Calibrators offer highly accurate calibration across pressure ranges up to 700 Bar. The HPX-700BAR calibrator is designed to generate high pressures up to 700 Bar and integrates a pressure generator and display within a single functional housing. This allows the user to rapidly build-up pressure and calibrate both mechanical and electronic pressure measurement devices through comparative measurements. The built-in display allows checking pressure readings in real-time and for leak testing of small pressurised systems.
Using the K114A and software, the readings can be sent to a computer and this allow the readings to be saved, processed or managed as the user desires. This can be used to generate reports for the testing being carried out and provide the data needed for internal paperwork. The 700 Bar range of the HPX-700BAR means this can be used to test sensors before being used in deep well drilling or offshore sites.
Supplied in a robust carrying case, the calibrator and its accessories are well-suited for field use.
