Risposta
It is recommended that the calibration on the DR300 should be checked every 3 months using SpecCheck Secondary Gel Standards. Regulatory agencies may have different requirements. 
A primary standard solution should also be used periodically to validate the test procedure, reagents, and instrument. Instructions for performing an Accuracy Check - Standard Solution Method can be found in the Hach method.

This is also true for the Pocket Colorimeter II.
