1413μS/cm and 12.88mS/cm EC Calibration Solution and pH Calibration Powder (pH4.00 pH 7.00 pH10.01) for Hydroponic pH EC Meter, Salinity Meter Salt Tester Calibration Fluid for Saltwater Pool
Package contents: 2 bottles (50ml each) of 1413 μS/cm EC calibration solution; 2 bottles (50ml each) of 12.88 mS/cm EC calibration solution; one packet each of pH 4.00, pH 7.00, and pH 10.01 pH calibration powder; An instruction manual card
Conductivity Standard Solution 1413μS/cm and 12.88mS/cm: The 1413 and 12.88 EC calibration solutions meet the calibration needs of most EC meters used in daily life, covering measurements of drinking water, hydroponic nutrient solutions, hydroponic basic water, freshwater fish, RO water, coffee, swimming pools, spas, etc. The combined packaging of 1413 and 12.88 mS eliminates the need to purchase them separately, avoiding calibration solution waste and saving money
Salinity Meter Calibration Solution 12.88mS/cm: Most salinity meters used in Salt Chlorination System on the market use 12.88 calibration solution. These salt meters are designed so that once the EC is calibrated using 12.88 calibration solution, the salinity will be automatically calibrated as well. Expensive salinity calibration solutions are unnecessary; the universal 12.88 EC calibration solution is sufficient for your salinity meter calibration needs for salt water pool
pH Calibration Powder: The package contains one packet each of pH 4.00, pH 7.00, and pH 10.01 calibration powder. Each packet of powder, when mixed with 250ml of filtered water, yields 250ml of pH 4.00, 250ml of pH 7.00, and 250ml of pH 10.01 pH calibration solutions. Store in containers and label each solution for subsequent pH calibrations (50ml can be used per calibration), avoid buying pH solution again
Features: The EC calibration solution is packaged in HDPE bottles with high-density sealing to prevent leakage; and the combined packaging of pH and EC calibration solutions significantly reduces your purchase costs
