Safe High Pressure Measurement now up to 5000 bar!

Designed to perform in demanding environments, the HP1100 & GD4200-USB Series from ESI Technology will consistently maintain accurate performance whilst sustaining high durability.

The wetted parts and diaphragm are machined from a single piece of titanium alloy which means no weld joints and therefore high pressure integrity and overload capacity andwith operating ranges up to 5000bar, the Silicon-on-Sapphire sensor technology ensures a high performance level even with high overpressures.

Stainless steel housing gives unbeatable corrosion resistance whilst the Silicon-on-Sapphire sensor technology provides outstanding performance with virtually no hysteresis and excellent long term stability over a wide temperature range. The standard autoclave fitting enables safe and reliable sealing to such high pressures.

The Genspec Dynamic digital USB Transducer, or the GD4200-USB, has a selectable read rate up to 1000 readings per second (1000Hz), ensuring that all pressure fluctuations are captured and you don’t miss a thing!

An optional ATEX and IECEx certified version of the HP1100 series is available for explosion protection for flammable gases (zone 0), dusts (zone 20) and mining areas (group I M1).
