Waterproof Tester Combo 1 1 piece

The world's first waterproof tester for measuring pH/EC/TDS/temperature. The everyday waterproof multi-function combo meter is compact but can measure pH, conductivity, TDS, and temperature with just one unit. The large, easy-to-read display allows you to replace the pH electrode. Measurement range: pH 0.00 to 14.00 pH, EC 0 to 3999 μS/cm, TDS 0 to 2000 ppm, temperature 0.0 to 60.0°C Detection units: pH 0.01pH, EC 1μS/cm, TDS 1ppm, temperature 0.1℃ Accuracy (at20℃): pH ±0.05pH, EC ±2%FS, TDS ±2%FS, temperature ±0.5℃ Calibration: pH automatic 1-point or 2-point calibration, EC automatic 1-point calibration Available buffer solutions: One of two sets of pH settings (pH 7.01 and pH 4.01 or pH 10.01, or pH 6.86 and pH 4.01 or pH 9.18), EC 1413μS/cm, TDS 1382ppm Temperature compensation: Automatic External environment of use: 0 to 50℃ Waterproof: Daily waterproof Power supply: 4 LR-44 button batteries Auto power off: after 8 minutes of non-use Size: Length 163 x Width 40 x Thickness 26mm Weight: 100g Accessories: 1 bag each of pH 7.01 & 4.01 standard solution, 1 bag each of EC & TDS standard solution, 1 bag each of electrode cleaning solution & electrode storage solution
