Product Categories

Gauges - LEO1, LEO2, LEO3, LEX1, ECO1

Battery powered or current loop powered LCD display pressure gauges with ranges from -1 to 1 bar up 1000 bar. Featuring max and min peak hold facility, multiple pressure units on most models, choice of pressure connections and grades of accuracy.

Loggers - LEO Record, LEO Capo

Internally powered data loggers for storing pressure readings for a finite time period or continously. Create a logging procedure with the provided desktop software and then download to the logger via a USB or RS232 connection. Decide when to start logging and when complete connect back to the desktop to upload the test data. For potentially explosive atmospheres there are also IS approved versions for use in refineries and on offshore platforms.

Transmitters - PD33X, PD39X, 41X, 23Ed, 25Ed

Intelligent sensors for measuring medium to high range gauge, absolute and differential pressures. All stainless steel 316L construction for use on fluids or gases with an internal micro machined silicon diaphragm sensing element. These sensors are digitally characterised over pressure and temperature to provide a high level of measurement accuracy. Options for ATEX approval and re-ranging via digital link.

Digital Sensors - 33X, 35X, PD33X, PD39X, 41X

RS485, RS232 and USB interface pressure transducers for connecting directly to a computer. Develop your own communication software with the provided RS485 prtotocol commands or install optional PC software for displaying and recording live readings.
