Technical description
The M9836 conductivity meter is suitable for water,
waste water or pure water conditioning in continuous or
batch-type operating modes, for liquid chromatography or
for general chemical process monitoring.
The accuracy is better than 0.5% at 2.25%/ ºC between
15ºC and 120ºC.
Temperature coefficient of the cell is compensated
either manually or automatically by an external Pt-100
platinum resistor probe within the range of 0ºC to
120ºC. The slope can be adjusted between 1.5%/ºC and
3.0%/ºC.
Commercially available conductivity cells -K-factor
0.01, 0.1 and 1.0 cover a dynamic range from 0.01µS to
20mS full scale. An internal synchronous rectifier
eliminates the capacitive error currents induced by the
cell cable.
The measuring signal is transferred to the output as a
signal current of either 0...20mA or 4....20mA. Two
floating limit or alarm contacts can be set over the
entire range. Each can be defined as a normally open or
as a normally closed contact.
Supply lines and all other lines, either from or to the
conductivity meter, are protected by internal noise
limiters against HF-noise.
