About Gravity: Analog Electrical Conductivity

wiki information: https://www.dfrobot.com/wiki/index.php/Gravity:_Analog_Electrical_Conductivity_Sensor_/_Meter_V2_(K%3D1)_SKU:DFR0300 APPLICATIONS Water quality monitoring. Aquaculture. Hydroponic & Aquaponic. Tips: In order to ensure the measurement accuracy, it is strongly recommended to add a temperature sensor to measure the temperature, and achieve automatic temperature compensation. DS18B20 waterproof temperature sensor can also be used. Attention: 1.The probe is a laboratory-grade probe. Do not immerse in liquid for a long time. Otherwise this will shorten the life of the probe. 2.Platinum black layer is attached to the surface of the sheet metal in the probe.It should avoid any object touching it. It can only be washed with distilled water, otherwise the platinum black layer will be damaged, resulting in inaccurate measurement.
