Keller LEO5 Digital Manometer (31bar)

The Keller LEO5 Digital Manometer is capable of measuring both absolute pressure (0 to 31bar) and relative pressure (-1bar to 30bar) with accuracy of ±0.05% and a resolution of 10mbar. It has a G 1/4” male pressure connector and is also capable of measuring temperature from 0˚C to 50˚C with ±1˚C accuracy.

Both temperature and pressure readings are shown concurrently on the Keller LEO5’s clear digital screen. The ‘peak’ capture mode takes 5000 readings per second and records the highest pressure alongside the current reading. Min/max and zero functions are available and the manometer also produces an analogue voltage or current signal alongside digital readouts.

The large 56,000-reading internal memory stores measurements with a time stamp and can be downloaded to a PC via the USB port. This can also be used to configure and recharge the monitor.

The Keller LEO5 benefits from stainless steel casing and a sealed safety glass front that give it an IP66 ingress protection rating. It is powered by a rechargeable battery that allows up to 1600 hours’ operation when it is fully charged.
