KELLER LEO Ultimate Bluetooth Data logger

KELLER LEO Ultimate Bluetooth Data logger

Product Description

 
 
 
   
 
The LEO Ultimate digital pressure gauge is a high-precision measuring instrument designed for demanding applications in calibration, service and industry. It combines piezoresistive measurement technology with advanced analysis functions, enabling both absolute and relative pressure measurements in a single device.

Thanks to the integrated barometer, it is possible to switch between the two pressure types at any time without the need for additional sensors. This allows the device to be used flexibly in a variety of applications.

The various measurement modes enable the analysis of static and dynamic pressure profiles as well as leakage tests. This range is complemented by a data logger function for recording over extended periods.

Parameterisation and data retrieval are carried out via USB-C or wirelessly via Bluetooth. In combination with the PressureSuite software, measurement data can be easily visualised and documented.

The robust metal housing with IP67 protection and the easy-to-read display allow the device to be used even under demanding environmental conditions.
