TDS EC Meter Specifications: TDS: 0-9990 ppm (parts per million) Conductivity: 0-9990 µs/cm Degrees Celsius: 0.1-80.0°C Fahrenheit: 32.0-176.0°F Accuracy: ±2% Battery: 1 * 3V CR2032 button battery (included) Item weight: 51g without case Item size: 15.4 x 3.0 x 1.4cm Package Includes: 1 x TDS EC Meter with Battery 1 x Leather Carry Case 1 x Instructions Manual How to use: 1.

After reading, please turn off the meter and wipe it clean. Note: 1. Keep the electrode clean, cover the electrode protective sleeve, and please take out the batteries for long periods idle. 2. EC unit is mS/cm, the normal range of EC is between 1-4mmhos/cm (and mS/cm) 1ms = 1000 us, so 400 uS/cm =0.4mS/cm, it is means 0.4EC. 3. TDS shows 0~9 pure water, 10~60 is Mountain spring water, mineral water, 60~100 is purified water, 100~300 is running water, over 300 is contaminated water.
