testo 6742 Dew Point Meter

Model No :

testo 6742

Part Code :

0555 6742

Overview

Testo 6742, NPT½ thread, without display dew point transmitter is specifically used for measuring trace humidity in compressed air or dry air. It contains a polymer humidity sensor which features a high degree of accuracy and long-term stability. This dew point transmitter helps to prevent damage by undersirable Humidity and moisture.

Features

- Measurement of dewpoints in the range from -60 °Ctd to +30 °Ctd
- 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
- Testo polymer humidity sensor with high accuracy and long-term stability
- Trace humidity adjustment without reference measuring
instrument possible on site with accessory (2-point
adjustment device)

Major Applications

It's suitable for measuring trace humidity in compressed air or dry air
- refrigeration dryers or membrane dryers.
