Feature 1Professional Design: The digital salinity tester is a accuracy meter for testing the salinity value of solutions. It displays both the salinity mg/L value and the temperature. 2Wide Ranges: The salinity tester has a measurement range of 0 to 1000 mg/L and can accurately, quickly and reliably test conductivity temperature, TDS temperature, and salt temperature for most conventional aqueous solutions. 3Applicable Industries: Portable salinity tester is fully functional, stable performance and easy to operate. Widely used in chemical, pharmaceutical, electronic, food and other industries for monitoring. 4Multi Function: Digital salinity tester adopts microcontroller technology, LCD display, automatic temperature compensation and temperature display function, one point correction. 5Built in Eelectrode: Digital salinity tester with electrode included, and the electrode can be replaced and the housing can be waterproof.Item Type:DigitalSalinityTesterMaterial: ABSWeight: Apporx. 226g/8.0ozSize: Approx. 188x38mm / 7.40x1.50in Display: Conductivity Temperature, TDS Temperature, Salt TemperatureSalinity Meter Technical Index: Measuring Range : 0~1000 Mg/LTemperature Compensation: 0~50Temperature Range: 0-50 (32-122F)Temperature Resolution: 0.1Temperature Accuracy: 0.2Automatic Power Off for 5 MinutesLow Power: YesCelsius Fahrenheit Temperature: YesData Retention: YesBattery: 4 x 1.5V LR44 Button Cell (Shipped Without Battery) .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Digital Salinity Tester (Batteries Not Included)1 x Manual1 x Storage BoxNotePlease allow some error in manual measurement.
