Works as described. By Christopher on 9/12/2019Christopher would recommend this product to a friendUsed to check calibration and read the meter read exactly as it was supposed to. Only issue was it came with the wrong directions telling me to add reagent to test tube B. Glad I checked Hanna's website before ruining the standard.
