The Testo 6744 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 6744 is a measuring range of -45 °Ctd to +30 °Ctd and excellent accuracy. For the display of the relevant trace humidity parameters, the Testo 6744 has a freely scalable analog output is available, optionally with a switch contact plug for MAX monitoring. In addition to this, the 6744 stands out thanks to its compact and user-friendly design, such as the rotatability of the housing by 350° for the optimum positioning of the display.
