Description
Keller LEO2 Digital Manometer
Introduction – Keller LEO2 Digital Manometer
The Keller LEO2 Digital Manometer is a compact, battery-powered precision pressure gauge designed for industrial applications requiring reliable and high-accuracy measurements. Built with an encapsulated piezoresistive pressure sensor and stainless-steel wetted materials, the LEO2 delivers ±0.1% FS accuracy and a total error band of ±0.2% FS, ensuring stable performance across a wide range of operating conditions. Its digital LCD provides clear visibility of real-time pressure, along with minimum and maximum recorded values.
With pressure ranges extending from 0…4 bar up to 0…700 bar, the LEO2 supports diverse measurement needs in maintenance, servicing, and calibration environments. The device is energy-efficient, operating for up to 1000 hours on a single CR2430 battery. For hazardous or explosive environments, an intrinsically safe certified version—LEO2-Ei (ATEX / IECEx)—is also available.
Engineers and technicians appreciate the LEO2 for its rugged construction, user-friendly interface, and dependable performance in demanding industrial settings. The product is commonly supplied and supported in the UAE and MENA region through specialized instrumentation distributors, including Dubai Sensor, ensuring quick access to stock and technical guidance.
