0555 6744 Dew Point Transmitter (with display; 1/2 NPT) by Testo

The testo 6740 was especilally 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 is a measuring range of -45 °C_td to +30 °C_td 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 stands out thanks to its compact and userfriendly design, such as the rotatability of the housing by 350° for the optimum positioning of the display.
