Brief description of the unit

The Portamess 911 Conductivity measures
conductivity, salinity, TDS and temperature in
the industrial, environmental, food and waste
water sectors.
The Portamess 911 Conductivity
The unit complies with the requirements of the
EMC Act and the NAMUR NE 21 recommenda‐
tions.
The unit's degree of protection is IP 66
according to DIN EN 0470 Part 1.
Temperature compensation is provided auto‐
matically with a Pt 1000 temperature sensor, an
NTC 30 kΩ (automatic detection when switched
on) or by manual temperature specification.
Calibration can be done by direct input of the
cell constants, by calibration with calibration
solutions KCl 0.01 mol/l or 0.1 mol/l or with any
other calibration solution.
Uninterrupted operation of the unit for approx.
1000 hours is possible with 3 mignon batteries.
To save battery life, the unit automatically
switches off after 1 hours if it is not operated.
