Test Equipment

Industrial humidity measurement requires top-tier professionalism, both in system operation and in the measuring technology itself. The testo 6681 industrial humidity transmitter, paired with the testo 661x probe series, meets these rigorous standards with ease.

Measuring flow rate, totalized consumption, and temperature in a single instrument, this compressed air meter suits large-diameter pipes from DN65 to DN250. Additionally, a TFT display shows three measurement values simultaneously and analog and pulse outputs support system integration. It uses the calorimetric measuring principle for accurate readings without pressure loss.
