Keller LEO5 Digital Manometer (4bar)

The Keller LEO5 Digital Manometer is a feature-rich, high precision industrial pressure gauge capable of measuring absolute pressure from 0 to 4bar and relative pressure from -1bar to 3bar via its G1/4” male pressure connection. Pressure readings are accurate to ±0.05% FS and precise to 1mbar. The manometer also has temperature measurement from 0˚C to 50˚C with ±1˚C accuracy.

Temperature and pressure readings are displayed simultaneously on the Keller LEO5’s digital display, whilst an analogue output with a 4…20mA or 0…10V signal. Peak reading capture record the highest and lowest readings with a measurement frequency of 5kHz whilst standard mode has a 2Hz sampling rate. Min/max recording and a zero function are both available.

The Keller LEO5 has a large internal memory with enough space for 56,000 readings with pressure, peak pressure, temperature and a timestamp. Data from the memory can be downloaded via the USB port and this also allows the user to recharge and configure the manometer from a PC.

A stainless steel enclosure and environmentally sealed safety glass front panel make the Keller LEO5 suitable for use in difficult conditions. It has an IP66 waterproof rating. The accumulator rechargeable battery can operate for up to 1600 hours when fully charged.
