When it comes to using testing equipment, it is crucial to not only make sure you’re using the right kit or piece of equipment for the job, but also that you know how to use them. A test will only yield accurate results if the person performing the test follows the proper steps as laid out in the instruction manual. And the steps have to be followed precisely, as any deviation could render the results of the test completely null. This is crucially important for all of the titration and colorimetric testing we perform for phosphate and silica, but also key when using PAR meters and refractometers. So, get to know the steps that the manufacturer spells out and follow then to the “t”.
