Full Description Specification

CalCheck standards for Magnesium Hardness, 0.0 and 1.00 ppm.

HI-96719-11 is a high quality set of calibration standards that allows users to validate and calibrate the magnesium and total hardness range found in compatible photometers that have a 0.00 to 4.70 mg/L (ppm) CaCO3 range. The HI-96719-11 includes one sealed “A” cuvette for zeroing the meter and one “B” cuvette that is used to validate or calibrate. The expected reading from the “B” standard is 1.00 ±0.05 mg/L CaCO3 @ 25°C. The calibration set is produced using reagent grade chemicals in a temperature controlled environment.
