NG # 02628-HW-KELLER-004
The Keller LEO2 is a compact, microprocessor-controlled digital pressure gauge designed for high-accuracy local pressure measurements. Featuring digital thermal compensation, it delivers an overall accuracy of 0.1% FS across a wide temperature band ($0\text{--}50^\circ\text{C}$), making it significantly more reliable than standard mechanical dial gauges.
