Specifications |
– 500mL orange label plastic bottle – Each bottle is tightly packed and sealed to ensure quality. – Colorless solution: The solution does not contain any dyes that could yellow or stain the electrode junction or reference cell. |
|
Using |
– Pour enough calibration solution into a clean plastic cup so that the electrode, sensor and junction are completely immersed in the standard solution. – Calibrate the electrode according to the electrode or meter's instruction manual. |
|
Methods of preservation |
– After use, cover and store at room temperature, away from direct sunlight – Do not dilute or add any chemicals to the solution. – Always use fresh solution for each calibration – ABSOLUTELY do not pour used solution back into the bottle. |
