The GF Signet 2850-101 Plug-In NIST Traceable Recertification Tool is intended for use in the
calibration or validation of conductivity/resistivity electronics that are independent of the electrode.
Because there are no available liquid standards for calibration in low conductivity and resistivity
applications, the GF Signet 2850-101 Plug-In NIST Traceable Recertification Tool is ideal for various
installations. The GF Signet 2850-101 is 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. The GF Signet 2850-101 Plug-In NIST Traceable Recertification Tool simulates,
within ± 0.1% accuracy, various values: 1.0 μS, 2.5 μS, 10.0 &;mu;S, 10.0 MO, 18.2
MO. The GF Signet 2850-101 is also temperature compensated to 25°C and enable the user
to accurately validate or calibrate the electronics.
The GF Signet 2850-101 Plug-In NIST Traceable Recertification Tool simulators are used with the
newly released Model 2850 electronics and simply plug into the same terminals as the sensor cables.
