[Make Your Salt/EC/TDS Meter More Accurate] EC calibration solution is essential for achieving accurate salinity/EC/TDS readings in saltwater pools and spas. Maintain balanced water by ensuring your salt meter is always calibrated correctly. This kit includes 4 individual 50mL bottles, providing you with an ample solution for multiple calibrations without the need for frequent restocking.
[Easy to Use and Store] It is already pre-mixed and ready to use, no more troublesome dissolution process. Adjust EC mode, press and hold the MODE/CAL key. When the value is calibrated to 5000μS/cm, the calibration is completed.
[Is Your EC Meter Still Accurate?] Without regular calibration, even the most precise EC, TDS and salinity meters readings are way off, affecting the water balance of your saltwater pool, hot tub, and spa. Use ORAPXI 5000 µS/cm calibration solution to ensure your readings stay precise.
[Universal Compatibility] This 5000μS/cm calibration solution is designed to work with any digital EC Meter, TDS Tester, or salinity test kit that supports 5000μS/cm calibration. Whether you're using a handheld tester, pen-style meter, or multi-parameter device, this solution ensures reliable calibration across the board.
[CAUTION] Keep away from children! Do not drink! Keep away from light, sealed and stored at low temperature. 2-year expiration from manufacture for an unopened bottle.
