Measuring flow rate, totalized consumption, temperature, and operating pressure in a single instrument, this compressed air meter suits 2" (5 cm) line compressed air systems. Additionally, a TFT display shows three measurement values simultaneously and two 4 to 20 mA analog outputs support system integration. It uses the calorimetric measuring principle for accurate readings without pressure loss.

The testo 6454 compressed air meter enables you to carry out accurate compressed air consumption measurements, consumption and leak monitoring and flow measurements in your compressed air system. The compressed air meter can also be used to carry out a peak load analysis in order to determine whether you are generating compressed air of sufficient capacity. This creates transparency when it comes to compressed air consumption and can help you save energy, reduce costs and implement a targeted environmental management system (e.g. as per ISO 50001 or ISO 14001). Overall, these measures can help you find potential for savings or prevent unnecessary investment costs.
