Description :

  -DFRobot Gravity: analog electrical conductivity meter V2 is used to measure the electrical conductivity of an aqueous solution and evaluate water quality -Often used in water culture, aquaculture, environmental water detection, and other fields -Upgraded version of electrical conductivity meter V1, improves user experience and data precision -Supports 3~5v wide voltage input, compatible with 5V and 3.3V main control boards -Output signal filtered by hardware for low jitters -AC signal excitation source reduces polarization effect and improves precision -Software library uses two-point calibration method and can automatically identify standard buffer solution -Can quickly build an electrical conductivity meter with main control board and software library, no welding required -Conductivity is the reciprocal of resistance and relates to a material's ability to carry current in liquid -Conductivity is an important parameter of water quality and reflects the presence of electrolytes in water.

Features:

•3.0~5.0V wide voltage input •Hardware filtered output signal, low jitter •AC excitation source, effectively reduces polarization •Gravity connector and BNC connector, plug and play, no welding •Software library supports two-point calibration and automatically identifies standard buffer solution, integrates temperature compensation algorithm •Uniform size and connector, convenient for the design of mechanical structures

Applications:

•Water quality monitoring •Aquaculture •Hydroponic & Aquaponic -Note: To ensure measurement accuracy, it is recommended to use a temperature sensor to measure the temperature and achieve automatic temperature compensation The probe is a laboratory-grade probe. Do not immerse in liquid for a long time as it may shorten the life of the probe. Avoid touching the platinum black layer on the surface of the sheet metal in the probe. It can only be washed with distilled water, otherwise, the platinum black layer will be damaged, resulting in an inaccurate measurement.
