DFRobot Gravity: analog electrical conductivity meter V2 is specially used to measure the electrical conductivity of an aqueous solution, and then to evaluate the water quality, which is often used in water culture, aquaculture, environmental water detection, and other fields. This meter product, as an upgraded version of the electrical conductivity meter V10, greatly improves the user experience and data precision. 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. Featured By RoboticsBD.
Tips: In order to ensure 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.
