1. General Description
The "SensoDirect" is a small, handy measurement
device, which can be used anywhere where conduc-
tivity has to be measured quickly and accurately. The
unit is very easy to use and is fitted with a digital dis-
play, reading to 2 decimal points. The measurement
range is 0 - 10.00 mS/cm. Because conductivity meas-
urement is dependent on temperature, the unit has a
manual temperature compensation facility, from
0 - 100
°
C.
2. Products supplied
• SensoDirect Basic unit, including electrode
• carrying case
• operating instructions
3. Setting to work
The unit is supplied as standard with a battery and is
therefore ready for immediate use, once the cinch
connector plug to the pH electrode is inserted into its
socket. The unit is switched on and off with the red
push-button to the side of the electrode connection.
4. Calibration
To ensure optimum accuracy of measurement, the unit
should be calibrated regularly. Determine the
temperature of the calibration solution and turn the
right-hand knob (the temperature compensation
control) to set the temperature which has been
determined : 1 line-mark is roughly equivalent to 10
°
C.
Rinse the electrode in fully demineralized water, dry it
