ECS-VI Conductivity Meter Verification Standard    Conductivity Meter Calibration Device

1  Technical Description
The Conductivity Meter Electrical Verification Standard is used to calibrate the electrical components of various conductivity meters, conductivity sensors, salinity meters, and other instruments. This standard complies with the verification requirements of "JJG376-2007 Verification Regulation for Conductivity Meters." Using this standard enables convenient completion of metrological verification tasks for conductivity meters.
The standard device is equipped with two standard conductivity input dials, K1 and K2, and a KT simulated temperature regulator. When using either K1 or K2, the other dial should be set to zero (single resistance connection). The standard conductivity input dials and the simulated temperature regulator can be used simultaneously.
2  Main Technical Specifications
Measurement Range
Conductivity: 0.05 μS to 2.5×10? μS;                Temperature: Approximately 10 to 50°C
Accuracy: 0.07% (1 μS to 2.5×10? μS);
0.1% (0.05 μS to 1 μS).
Note: This accuracy is relative to the factory value. The conductivity values of the instrument are based on the factory calibration certificate.
