The Signet Conductivity/Resistivity Tools are available for certification 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 certify 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.
