Keller LEO 5 Digital Manometer – 101 Bar Absolute

Introduction – Keller LEO 5 Digital Manometer – 101 Bar Absolute

The Keller LEO 5 Digital Manometer – 101 Bar Absolute is a high-precision, Swiss-engineered measurement instrument designed for demanding industrial, calibration, and laboratory environments. Equipped with a high-resolution piezoresistive pressure sensor encapsulated in stainless steel, it ensures exceptional accuracy and long-term stability across the entire measurement range. Its absolute pressure span of 0…101 bar (0 bar abs reference) makes it suitable for applications requiring true absolute pressure measurement rather than gauge-based readings.

The instrument features a robust stainless-steel housing with a safety-glass front panel and capacitive touch controls, offering durability in harsh field conditions. The large backlit display presents pressure, temperature, bar-graph indication, and min/max values with excellent clarity. The LEO 5 also integrates a 56,000-point data logger, peak detection at 1 kHz, and a Mini-USB interface for configuration and data export. These capabilities make it ideal for industrial teams, calibration workshops, and engineering professionals looking for reliable, traceable pressure measurement.

For organizations operating across the UAE and the wider MENA region, the instrument’s rugged stainless-steel construction and wide temperature tolerance provide strong performance in both indoor facilities and challenging outdoor industrial locations. Dubai Sensor supports availability, configuration guidance, and professional integration for the Keller LEO 5 series.
