 The conductivity meter CD 22 is a portable, battery-operated meter with LCD Display for combined measurement of conductivity and temperature. It offers a number of useful functions:
Automatic selection of the measuring range after switching on (Auto Range Function). A key press converts the meter to manual selection of the measuring range.
The facility for continuous logging of minimum and maximum values which can be viewed at any time without interrupting measurements.
A HOLD function which freezes the display at the current reading.
Automatic switch-off if the instrument has not been used for 30 minutes.
A rugged electrode with excellent temperature stability and a measuring range of 0.1 mS to 200 mS.
The instrument comes as a complete kit including a conductivity electrode with integrated temperature sensor and accessories in a carrying case.
