Overview

Brief description: The method of testing conductivity with a portable conductivity meter | detector is to apply a DC voltage generated by an oscillator to an electrode (the purpose of applying an AC voltage is to avoid polarization of the electrode), generate a current in the conductivity cell, which is proportional to the electrical conductivity of the measured solution. After current voltage conversion, amplification, and detection, it is converted into a DC voltage, compensated by temperature, and finally converted into a digital signal by an A/D converter, which is displayed on a microcomputer. The entire process is controlled and processed by a microcomputer.

Product Details

1Product Introduction:

1. Product principle:

Conductivity, a physical concept, refers to the product of the quantity and the electric field strength in a medium, which is equal to the conducted current density. It can also be called conductivity. For isotropic media, conductivity is a scalar; For anisotropic media, conductivity is a tensor. In ecology, conductivity is the ability of a solution to conduct electrical current, represented by numbers. The unit is Siemens per meter（Represented by S/m.

The method of testing conductivity with this instrument is to apply a DC voltage generated by an oscillator to the electrode (the purpose of applying an AC voltage is to avoid polarization of the electrode), generate a current in the conductivity cell, and this current is proportional to the conductivity of the measured solution-Voltage conversion, amplification, detection, conversion to DC voltage, temperature compensation, etc., finally converted to digital signal by A/D converter, displayed by microcomputer. The entire process is controlled and processed by a microcomputer.
