12.88 mS/cm EC Calibration Buffer Liquid, Conductivity Salinity Calibration solution Fluid for Salt Tester, EC Meter, TDS Meter,5 in 1 Tester and 7 i Description

12.88 mS/cm EC Calibration Buffer Liquid, Conductivity Salinity Calibration solution Fluid for Salt Tester, EC Meter, TDS Meter,5 in 1 Tester and 7 in 1 Tester Calibration, 4 Bottles of 50mL(4*50ml) Accurate TDS EC Salt Readings Every Time ： Why is the salinity meter you received inaccurate? Why is the salinity value deviating greatly and inaccurate after using it for a period of time? No need to buy a new salinity/ec/tds meter, just choose 12.88 mS/cn calibration solution to help you solve these problems, making your salinity meter conductivity meter more accurate and last longer! Easy Storage! ---- Small package at 4 bottles of 50mL of calibration solution. EC conductivity solution values are prone to change after opening . Use only a small part each time, the unopened solution is not contaminated. Convenient to use. Calibration Frequency------For swimming pools, it is recommended to calibrate EC 12.88 every 2 months. For aquariums, it is recommended to calibrate EC 12.88 every 1 month. Calibrate in the following situation------①When you change a new electrode ②When the electrode hasn't been used for a long time ③Your required accuracy of tds ec measurement is very high Suitable for Salinity tester, TDS METER, EC Meter of all brands which have 12.88mS/cm calibration points.
