Description

KELLER LEO Ultimate Digital Pressure Gauge (100 bar)

The KELLER LEO Ultimate Digital Pressure Gauge (100 bar) is a high-precision pressure measurement instrument designed for industrial monitoring, hydraulic system testing and maintenance applications, thanks to its measuring range of 0-100 bar. It can be used to monitor operating pressures in hydraulic equipment, industrial machinery, pumps and pressure testing installations where dependable measurements are required.

Using high-precision piezoresistive sensor technology, the LEO Ultimate delivers accurate and dependable pressure measurement with a standard accuracy of ±0.05% FS and an optional ±0.01% FS accuracy version. In addition to displaying live pressure values, the instrument provides advanced measurement and diagnostic functions that help users monitor pressure changes, capture peak events, identify fluctuations and evaluate system performance.

Combined with its data-logging capabilities that record up to 800,000 measured values, the instrument also provides a useful way to record measurements for maintenance, performance checks and pressure analysis.

Measurement Functions, Data Logging and Connectivity

Designed for more than straightforward pressure readings, the LEO Ultimate offers several measurement functions, including: 

  • Minimum and maximum values
  • Leak testing
  • Pressure rate monitoring
  • Peak detection
  • Alarm settings

These measurements can be transferred via USB-C or Bluetooth for convenient data management.

Software Compatibility

The KELLER LEO Ultimate Digital Pressure Gauge is compatible with KELLER's PressureSuite software, available as PressureSuite Mobile for wireless field operation and PressureSuite Desktop for managing, visualising and processing measurement data on a Windows computer.

PressureSuite Mobile

Available for Android and iOS, PressureSuite Mobile connects to compatible KELLER instruments via Bluetooth, allowing users to configure the gauge and retrieve recorded measurement data without additional hardware. It supports measurement modes such as Min/Max, Leak, Peak, Rate and Alarm, along with channel selection, interval settings, display customisation and pressure zero-point adjustment. The app offers continuous or scheduled data logging with flexible memory management and allows data visualisation, processing and export in formats such as CSV, JSON and image files for further analysis and documentation.

PressureSuite Desktop

For more detailed data management, PressureSuite Desktop is Windows-compatible software used to retrieve, visualise and process recorded measurements from compatible KELLER instruments. Like the mobile application, it includes the same configuration and logging functions, while adding export options for CSV, JSON, Excel, images and Word reports. The software also supports pressure zero-point adjustment and the configuration of data-logging functions. Measurement-point information, including parameters used for water level calculations, can also be stored directly in the instrument to support post-processing.

Both PressureSuite Mobile and PressureSuite Desktop are licence-free, providing convenient ways to configure compatible instruments and manage measurement data without additional software licensing costs.

Display Features

The large backlit display offers an adjustable resolution from 4 to 5½, allowing users to optimise the presentation of measurement data for different applications and operating conditions.

It offers a wide range of selectable pressure units such as bar, mbar, psi, Pa, kPa, MPa, mH2O, mmH2O, inH2O, ftH2O, mmHg, inHg, kgf/cm²; with five additional custom pressure units being able to be configured using KELLER's PressureSuite software.

Robust Construction

The LEO Ultimate features a robust metal housing and IP67 protection rating which helps safeguard it in demanding working environments. Combining high measurement accuracy, versatile measurement functions and data-handling capabilities, the KELLER LEO Ultimate is a practical solution for professionals who require dependable pressure measurement and analysis.
