Technical description
The M2136 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.
Temperature coefficient of the cell is compensated either
manually or automatically by an external Pt-100 platinum
probe within the range of 0°C to 120°C.
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.
Optionally, a galvanic isolated and in the range of 0...20mA
programmable output signal for the conductivity signal or
temperature is available. By a external 24V signal, the
current output can be switched between conductivity- and
temperature measuring.
Two floating limit or alarm contacts can be set over the
entire range. Each is 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.
