4.Waiting for the reading is stable in 5 seconds,press the hold key and check the reading.
5.After using,dry the test pen,press ON/OFF for 3 seconds and it will shut down,then put the cap back on it.

Temperature Test Instructions:
1.Remove the TDS pen cover and use it in liquid or air.
2.Pressing the TEMP key,the display will convert to a Celsius display,press the key again to convert to Fahrenheit temperature test,then press the key third time to return to water quality test.

Influence factor
1.Water temperature:TDS meter pen can not to measure the hot water bodies.
2.The velocity of water flow:TDS pen can not to measure the large velocity of water flow.
3.Area:TDS values vary from region to region and city to city due to different pipelines and water sources.
