Test Equipment

Achieve professional-level compressed air consumption measurement with the testo 6448 compressed air meter. It offers precise readings and the convenience of easy bar probe removal.

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.

Additionally, a patented quick-change fitting allows the sensor to be removed from the process under pressure. It uses the calorimetric measuring principle for accurate readings without pressure loss.

The testo 6651 rises to special challenges. Paired with the testo 660x probe series, it becomes the top choice for demanding air conditioning technology and a wide range of other applications.

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.

Designed for building air conditioning applications, this humidity and temperature transmitter is available in wall or duct versions with a long-term stable humidity sensor. Additionally, two analog outputs cover temperature and humidity, and P2A software supports parameterization, adjustment, and analysis. It suits both room and duct installations, with an optional 2-line LCD display.

Designed for greenhouses and laboratories, this humidity and temperature transmitter monitors critical climates for biological research with a long-term stable humidity sensor rated at ±2.5% RH. Additionally, an integrated ventilator directs airflow onto the sensor for an averaged climate reading. Its housing integrates the probe to protect electronics from moisture.
