How is the Quick Cal-Cube™ used to check the calibration of the 4-Beam Turbidity sensor?
The Quick Cal-Cube™ is the simplest method available for checking the calibration of the 4-Beam Turbidity sensor. After calibration with primary standards, the value of the optional Quick-Cal Cube™ secondary standard, if used, must be determined and recorded for each individual instrument. The Quick-Cal Cube™ value is determined by removing the storage/calibration cups, wiping the optical areas, both sensor and cube, clean and dry with a non-abrasive, lint free cloth, and placing the ceramic glass cube into the turbidity sensor’s optical area. Align the Quick-Cal Cube™’s pin with the turbidity sensor’s recessed hole and, for optimum repeatability, rotate the Quick-Cal Cube™ clockwise to remove mechanical play in the pin/hole. To test for drift between primary calibrations, reinstall the Quick-Cal Cube™.
