Combined Floating Thermometer and Salt Meter: The YINMIK Pool Tester integrates a pool thermometer with a saltwater salinity meter into one device. It measures salinity from 0-9990ppm and temperature from 32.0-122.0℉ / 0.0-50.0℃ so you can check both values at any time. 24-Hour Continuous Monitoring: Built with an IPX8 waterproof housing and a polymer salinity probe, this tester continuously monitors changes in pool salinity and water temperature around the clock. The unit includes ATC (Automatic Temperature Compensation) so salt readings remain accurate despite temperature fluctuations. Solar-Powered, No Battery Swaps or USB Required: The meter harvests sunlight to recharge, eliminating battery replacements and USB charging. A full 8 hours of sun charging provides 6-8 days of operation when used in an indoor pool. Ready to Use — No Calibration Needed: The device comes factory calibrated for immediate, reliable salinity and temperature readings. Automatic Measurement & Hold: The tester automatically samples salinity every 2 minutes and locks (holds) each measurement for 2 minutes for easy viewing. Easy-to-Read Angled Display: The screen is set at a 30° reading angle for comfortable visibility of results.
