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 °Ctd to +30 °Ctd and excellent accuracy.
- Measurement of dewpoints in the range from -45 °Ctd to +30 °Ctd
- Testo polymer humidity sensor with high accuracy and long-term stability
- Convenient operation via the display menu
- Analog output 4 to 20 mA (2-wire) and optional alarm plug with 2 integrated switch outputs
- Compact design with rotatable housing by 350° for optimum positioning of display
- Display with operating menu (optional)
- Trace humidity adjustment without reference measuring instrument possible on site with accessory (2-point adjustment device), replaces expensive adjustment with dewpoint mirror
- Refrigeration dryers
- Membrane dryers
- Adsorption dryers
- Granulate dryers
