The Cyco Calibration Solution EC 2.76 offers precise calibration for Conductivity (EC) and TDS Meters. Calibrating to 2.76mS/cm or cF 27.6 at 25°C (77°F), it contains Potassium Chloride and is formulated based on the international APHA standard. While it gives accurate readings, users should remember to replace the solution every 7-14 days, particularly when working with salt-rich makeup water.
