About this item

• This option includes pH 4.00, pH 7.00 and pH 10.01. Please select the appropriate pH calibration solution for calibration according to the pH value of the sample.
• 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
• Large Capacity: Each pH solution bottle contains 250ml, suitable for long-term use with all pH meters and ideal for pharmaceutical, academic, research and industrial laboratories. The bottle mouth is sealed with a thick foam pad and an easy-to-tear gasket, providing double-layer protection to prevent liquid leakage
• 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
• 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.
