The Calibration Kit has been created to provide all the necessary components to enable customers to verify the accuracy of the readings on the Buckleys or Roxby BathyCorrometers so that ‘in-house’ calibration certificates can be issued. The process requires two areas to be checked. The electronics should be tested using the BCM Checker. Readings on the BathyCorrometer® should be 0.000 with the CalChecker switched off and 1.990 with it switched on. Providing the readings are correct, the silver/silver chloride screw-in half cell should be checked by using K-SAT reference cells in a standard salt water solution. To confirm the readings, three cells should be used and the sea water corrosion test mixture should be made up to a 3% solution.
