Description
The Keller LEO5 is a high-resolution digital manometer with ±0.05% FS accuracy (±0.1% FS total error band from 0 to 50 °C), available from −1…1 bar to 0…1,000 bar with resolution down to 0.0001 bar. It combines a data logger of 56,000 time-stamped readings with 1 kHz pressure-peak detection, temperature display and a bar graph on a large backlit screen.
Its watertight stainless steel housing has a safety-glass front and capacitive touch keys, and the built-in Li-ion battery lasts up to 2,000 hours and charges over USB. It suits pressure testing, calibration and laboratory work.
