For Optimal Performance, Re-Calibrate Periodically (Once a Week)! If the EC/Salinity PPM Meter has not been used for a long time or has not been cleaned after frequent use or after replacing a new probe, it is easy to cause inaccurate readings. For optimal performance, re-calibrate the meter periodically. As a Reference or Test Solution, Check it Once a Week! 12.88 mS/cm calibration solution can be used as a reference or check solution to make sure you have adequately cleaned the EC/Salinity/TDS Probe. Contamination between solutions can easily occur, affecting the validity of the probe, so you need the calibration solution for your daily inspection. Suitable for All EC /TDS/Salinity Meter! Once EC (conductivity) is calibrated, TDS and Salinity will be automatically calibrated. Not only for YINMIK testers, but also for any tester on the market. As long as 12.88 mS/cm, calibration point is supported, you can use it to calibrate, whether it is EC meter, TDS meter or salinity meter. Which Models of YINMIK Tester Support 1413μS/cm Calibration?

Review: Accurate test meter - The calibration packs are essentially the only way to insure an accurate water test meter stays accurate. I recalibrate once a month no matter what.
Review: Worked great and was a life saver - Purchased these for calibrating my ph meter and they worked just like they say. You mix each of the powders in their own container of water then you dip your ph meter in the solution and your meter will be calibrated to the value of the powder. Once you do it 3 times once in each of the solutions your ph meter should be calibrated and ready for use. You get 3 different powders and 5 packets of each one so you have more for later down the road when your meter needs calibrated again you will be set and ready to go making this a great value for the money. Seems to be pretty accurate I have tested with multiple meters and they are are very similar. Each packet is sealed separately so it's easy to store until your next use. I am happy with my purchase and will buy again when I run out of my supply. Thank you and have a blessed day!
