Liquid Conductivity Meter

The ESI Series Digital Pressure & Temperature Chart Recorder by Hydrorex is engineered for precision hydrostatic testing in demanding field and laboratory environments. Unlike traditional paper chart recorders, the ESI-PC combines a full Windows-based PC with a 12-inch touchscreen, enabling operators to visualise, log, and certify pressure tests digitally from a single portable unit.

The system's stainless steel panel and weatherproof carry case make it equally at home on an offshore platform or a controlled test facility. With 12 models spanning 250 PSI to 60,000 PSI and a broad ecosystem of rated hoses and adapters, it covers virtually every hydrostatic testing application in marine, oil & gas, and heavy industry.
