Package Included:
4  x TDS EC Meter
4  x PU Leather Cover
4  x User manual

Note:
1.Keep the electrode clean ,cover the electrode protective sleeve,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(or 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.
