Model Description
Product details
Testo's thermal flow meter can perform accurate compressed air consumption measurement, consumption and leakage, and flow measurement in the compressed air system. This thermal gas flow meter can also be used for peak road analysis to determine whether sufficient capacity compressed air is generated. This creates transparency in consumption of compressed air, which helps the implementation of energy savings, cost reductions, and the implementation of an environmental management system (ISO50001 or ISO14001, etc.) that focuses on the target.
Testo6456 Technical merit of thermal gas flow meter
• Measure four items: flow speed, flow rate, temperature, and pressure with one unit.
• Direct monitoring of compressed air that displays three measured values at the same time in the standard TFT display
• Best system integration: dual analog, pulse and analog output
• Instead of pressure loss due to heat measurement principles
• Flexible: Configuring to DN65 to 250 for distribution.
You can search for other models from each index. The displayed value is the value of the currently selected part number.
