The 3.5-inch color touchscreen provides fast, intuitive, and user-friendly operation even in field applications.
The integrated Li-Ion battery provides approximately 8 hours of continuous operation, ensuring complete mobility without external power sources.
Up to four sensors or measuring devices can be connected, including third-party sensors, with power supplied directly from the device.
All measured values are securely stored on a memory card; data can be transferred via USB or optionally through an Ethernet connection.
Enables calculation of production costs in € per m³ of compressed air, kWh/m³ analysis, and consumption evaluation of individual lines with summation functions.
Fast installation without modifications to the system significantly reduces measurement time and lowers the cost of diagnostic and energy audits.
