Solutii calibrare

GroLine calibration solution is available in a variety of sizes based on the frequency of use. Infrequent use includes users that calibrate and measure on a weekly or monthly basis. It is important that the solution be used within six months of opening a bottle. Solutions should be changed after six months for optimum performance. All solutions are supplied with a COA and include Quick CAL solution that is used for both pH and EC/TDS calibration. This dual-purpose calibration solution is used with compatible meters with the Quick Cal mode or with pH and conductivity meters that calibrate to pH 6.86 and 5.00 mS/cm.
