Georg Fischer 2850-101 Data Sheet
Signet Conductivity/Resistivity Tools
2830 2831
Description
The Signet conductivity/resistivity
tools are available for calibration or
validation of electronics that are independent of the electrode. Because
there are no available liquid standards
for calibration in low conductivity and
resistivity applications, these tools
are ideal for various installations. All
tools are built to conform to the ASTM
D 1125-95 Standard (Standard Test
Methods for Electrical Conductivity
and Resistivity of Water), which is also
commonly used for USP 24 applications.
Signet tools simulate, within ±0.1%
precision (accuracy), various values:
1.0 μS, 2.5 μS, 10.0 μS, 10.0 MΩ, 18.2
MΩ. These tools are also temperature
compensated to 25°C and enable the
user to accurately validate or calibrate
the electronics.
Model 2830 can be used with Signet
Models 5800CR, 8850, and 8860 instruments. The 2850-101-X simulators are
used with the newly released Model
2850 electronics and simply plug into
the same terminals as the sensor
cables.
