The calibration solutions are sealed and can be stored at room temperature until they are opened and used for the first time - then refrigeration is recommended so they stay "fresh and accurate". Suitable for All TDS Meter, EC Meter, Water Tester, Salinity Meter! Why You Need EC/Salinity/TDS Calibration Solution? For optimal performance, please recalibrate regularly (once a week)! Accuracy : Calibration helps in maintaining the accuracy of the instrument, ensuring that the readings reflect the true values of the samples being tested. Precision : Regular calibration ensures that the instrument provides consistent results over repeated measurements, enhancing the reliability of data. Extended Lifespan : Regular calibration can help in maintaining the performance of the instrument, potentially extending its lifespan by ensuring it remains in good working condition. Optimal Functionality : Calibration ensures that the instrument operates optimally, reducing the risk of malfunction or erroneous readings. 1413 μS/cm Calibration Solution for TDS Meter, EC Meter, Water Tester 12.88 mS/cm Calibration Solution Conductivity Salt Standard Buffer Solution. 111.8 mS/cm Calibration Solution for Salinity Tester, EC Meter, Pool Salt Tester Review: Make sure you get the right scale for your meter. 111mS is very high concentration - I am giving this solution a neutral review. I got this and tried to calibrate my TDS meter used for hydroponic solution mixing. Alas, this is a much, much higher concentration used for very high TDS / EC(conductivity) like those found in Wastewater/sewage testers. I ended up getting the 1413uS/cm solution for my needs from the same company and it worked great at calibrating my meter. I love the 4 bottles so that once one has been contaminated and is no longer calibrating accurately, it can be discarded and another bottle used. I gave 3 stars because when the product arrived, 2 of the bottles were wet. The plastic coated paper seal had been ruptured around the glued seal and the solution was able to exfiltrate a bit. I assume this would have contaminated the solution somewhat. Review: contaminated. - Although the delivery was quite quick, the pruduct is contaminated with what looks like mold. Outside of the bottles were quite dirty, I suspect the product was on shelf for a long time. ## Features - Convenient 4-Bottle Kit: This kit includes 4 individual 50mL bottles, providing you with ample solution for multiple calibrations without the need for frequent restocking.
