Item Type: Water Conductivity Sensor_x000D_ Signal Adapter Board: _x000D_ Input Voltage: DC3.3~5.5V_x000D_ Output Signal: 0~2.3V_x000D_ Working Current: 3~6mA_x000D_ Measurement Range: 0~1000ppm_x000D_ Measurement Accuracy: 10% F.S. (25)_x000D_ Size: Approx. 42 x 32mm / 1.7 x 1.3in_x000D_ Module Interface: XH2.54-3P_x000D_ Electrode Interface: XH2.54-2P_x000D_ Probe: _x000D_ Number of Probes: 2_x000D_ Overall Length: Approx. 83cm / 32.7in_x000D_ Connection Interface: XH2.54-2P_x000D_ Color: White_x000D_ Other: Waterproof probe_x000D_ Product Introduction: _x000D_ This equipment can be used for the measurement of general household water quality._x000D_ Generally, the tap water is within 100 and the purified water is within 10._x000D_ The compatible sensor is used to measure the value of water. The value can reflect the cleanliness of water and can be applied to water quality testing in the fields of domestic water and hydroponics._x000D_ (Total Dissolved Solids): Indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. In general, the higher the value, the more lysate is contained in the water and the more unclean the water. Therefore, the size of the can be used as one of the basis for reflecting the cleanliness of the water._x000D_ The commonly used testing equipment is a pen. Although it is inexpensive and easy to use, it cannot transmit data to the control system, do long-term online monitoring, and analyze the water quality. Using a special instrument, although the data can be transmitted, the accuracy is high, but the price is very expensive. To this end, we have specially introduced this compatible sensor, which can be used to measure the value of water after connecting to the controller._x000D_ this product is plug and play and easy to use. The wide voltage supply of 3.3~5.5V and the analog signal output of 0~2.3V make this product compatible with 5V, 3.3V control system, which can be easily used in the ready-made control system. The excitation source used for measurement uses an AC signal, which can effectively prevent probe polarization, extend probe life, and increase the stability of the output signal. The probe is a waterproof probe that can be immersed in water for long periods of time._x000D_ The product can be applied to water quality testing in the fields of domestic water, hydroponics and the like. With this sensor, you can easily DIY a detector, and easily check the cleanliness of the water to make your water quality better. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
