High Precision pH Buffer Calibration Solution Kit with Stable Ingredients:Reports values with an accuracy of +/- 0.01 pH at 25°C. You can use the GIDIGI pH meter for a longer period of time and get an accurate pH buffer calibration solution.It does not evaporate easily after opening, ensuring accurate readings. Notes: The solution is valid for 1.5 years after opening, 3 years if unopened
222mv ORP Calibration Solution :Checking ORP accuracy and sensor conditioning. Standard solutions designed for the calibration of oxidation reduction potential (ORP)/redox electrodes. 222mV ORP solution are used to ensure accurate electrode performance.Suitable for general water solutions' applications such as water treatment, groundwater, surface water, hydroponics, environmental monitoring, beverage making, etc.
Color-Coded for Easy Identification: pH 4 is pink,pH 7 is green,pH 10 is blue. In the laboratory, it is used to calibrate pH meters to ensure the accuracy of experimental results; In industrial production, it is used to monitor and control the pH in the production process; In environmental monitoring, it is used to assess the pH and pollution degree of water; In food testing, it is used to detect the pH and safety of food.
About the GIDIGI pH Calibration:7.0 is always the first calibration point,for neutral sample, calibrate 7.0 is ok,for acidic sample, calibrate 7.0-4.0 point,for alkaline sample, calibrate 7.0-10.0 point,unknown properties of the sample, calibrate 7.0-4.0-10.0 three points
High Quality ORP Solution: ORP Calibration Standard Solutions are accurate in reading and easy to use. Reliable and consistent results allow for optimal water quality control. Essential for maintaining a healthy aquatic environment. ORP solutions help meters improve response time and measurement accuracy.
