KELLER LEO 5 Digital Manometer – 10 Bar

Introduction – KELLER LEO 5 Digital Manometer – 10 Bar

The KELLER LEO 5 Digital Manometer – 10 Bar is a high-resolution precision instrument engineered for demanding industrial, laboratory, and calibration environments. Equipped with an encapsulated piezoresistive sensor and manufactured in a robust stainless-steel housing, it provides stable and highly accurate pressure readings within the –1 to +10 bar gauge range. Its advanced measurement electronics ensure ±0.05% FS accuracy and a ±0.1% FS total error band across the 0…50 °C compensated temperature range.

Designed for both field and bench applications, the instrument features a large backlit LC display, capacitive touch controls, and multi-mode data visualization including bar-graph, temperature, and min/max values. The internal logger stores up to 56,000 timestamped pressure and temperature readings, making it suitable for long-term monitoring and traceable documentation. Dubai Sensor supports this model across industrial facilities, calibration centers, and project sites in the UAE and wider MENA region.

The integrated USB (Mini USB-B) interface enables efficient device configuration, data export, and connectivity with KELLER’s free PressureSuite Desktop and ManoConfig software tools. With long battery autonomy — up to 2000 hours in standard operation — the LEO 5 is ideal for portable measurements or continuous monitoring tasks.

Its rugged IP65-rated stainless-steel construction and AISI 316L wetted materials ensure durability even in harsh environments, supporting a wide range of industrial applications including pressure testing, process verification, and laboratory diagnostics.
