KELLER LEO2 high-precision digital pressure gauge
- Manufacturer: Keller
- Category: Pressure gauges, Pressure, SENSORS
High-precision compact digital pressure gauge for measuring, checking and calibrating pressure in industrial applications.
He KELLER LEO2 It is designed for maintenance, commissioning, installation verification and pressure control in hydraulic, pneumatic and test bench systems.
It is available in pressure ranges from 0…4 bar to 0…700 bar and offers an accuracy of
≤ ±0.1 % of the full scale at a temperature of 20…25 °C. Its total error band is
≤ ±0.2 % FS within the compensated range of 0…50 °C.
The two-line LCD screen allows simultaneous viewing of the current pressure and the minimum or maximum value reached since the last reset.
The device features zero point adjustment via the front buttons, automatic shut-off, and selection of different pressure units.
- Display of current pressure and minimum and maximum values.
- Selectable units: bar, mbar, hPa, kPa, MPa, PSI and kp/cm².
- Zero point adjustment using buttons.
- Configurable automatic shutdown.
- The indication is updated twice per second.
- Autonomy of up to 1,000 hours of continuous operation.
The LEO2 incorporates a pressure connection 7/16-20 UNF and comes with a swivel adapter
G1/4 male, which allows the instrument to be oriented to facilitate reading once installed.
The connection and separator membrane are made of AISI 316L stainless steel.
Its compact design, the protection IP65 Powered by a CR2430 battery, it is a practical solution for industrial maintenance, machinery testing, instrument calibration, and pressure testing.
For installations in potentially explosive atmospheres, the version is available
LEO2-Ei intrinsically safe, certified in accordance with ATEX and IECEx regulations.
