The Testo 6740 series was especially developed for trace humidity measurement in compressed or dry air (e.g. granulate dryers) Thanks to a special adjustment, optimum accuracy in the trace humidity range has been achieved. The result of the development of the Testo 6740 series is a measuring range of -45°C to +30°C and excellent accuracy.
For the display of the relevant trace humidity parameters, a freely scalable analog output is available, optionally with a switch contact plug for MAX monitoring. In addition to this, the Testo 6740 series stands out thanks to its compact and user-friendly design, such as the rotatability of the housing by 350° for optimum positioning of the display.
