It supports 3~5v wide voltage input, and is compatible with 5V and 3.3V main control board; The output signal filtered by hardware has low jitters; The excitation source adopts AC signal, which effectively reduces the polarization effect, improves the precision, and prolongs the life of the probe; The software library uses two-point calibration method, and can automatically identify standard buffer solution, so simple and convenient.\u003cbr\u003eWith this product, the main control board (such as Arduino), and the software library, you can quickly build an electrical conductivity meter, plug, and play, no welding. DFRobot provides a variety of water quality sensor products, uniform size, and interface, not only meet the needs of various water quality testing but also suitable for the DIY of multi-parameter water quality tester.\u003cbr\u003eConductivity is the reciprocal of the resistance, which is related to the ability of the material to carry the current. In the liquid, the reciprocal of the resistance, the conductivity, is the measure of its ability to conduct electricity. Conductivity is an important parameter of water quality. It can reflect the extent of electrolytes present in water.\u003c\/p\u003e\n\u003cp\u003eBest for intermittent laboratory sampling. This K=1 kit is recommended for 1–15mS\/cm measurements and includes calibration solutions. Do not choose a continuous-use probe by immersion rating alone: its conductivity range must also match your sample. Temperature compensation requires a separate temperature measurement.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan style=\"color: #ffffff;\"\u003e Tips:\u003c\/span\u003e\u003c\/span\u003e\u003cbr\u003eIn order to ensure measurement accuracy, it is strongly recommended to add a temperature sensor to measure the temperature and achieve automatic temperature compensation.
