Intelligent online corrosion tester model

Intelligent corrosion detector/Corrosion rate meter model: H134626

1、 Product Features
1) Product Features and Applications
*LED backlit 2.8-inch color intelligent controller with clear display and lower power consumption.
*Simultaneously possessing three types of curves:
Real time curve: visually displays what has happened in the past and present.
Historical curve: It can query the curve chart of any time period during the running period.
Fitting curve: a graphical representation of the running data using the least squares method.
*It has multiple language switching functions.
*Switching function between two units of mm/a and mpy.
*Two channels simultaneously measure the corrosion rate quickly (taking 150 seconds).
*Point corrosion and average corrosion can be measured in real-time.
*There is a current amplifier in front of the sensor, and the wiring between the instrument and the sensor can be extended
(Transmission distance greater than 500 meters)
*PhotoMOS optocoupler relay with four independent controls, with unlimited lifespan.
Alarm, control, pulse output and other functions can be configured arbitrarily.
*Equipped with two high-resolution isolated 0/4-20mA outputs, configurable.
(The two routes are also isolated from each other)
*One way isolated 485 communication, configurable as MODBUS communication.
*Applied to industrial water, chemical, pharmaceutical, environmental protection, printing and dyeing, metallurgy, electronics
Electroplating, water treatment, aquaculture and many other industries.

2）Intelligent corrosion detectorMeasuring principle
Adopting a combination of linear polarization resistance (LPR) and alternating current impedance spectroscopy (EIS) technology.
The polarization resistance Rp is related to the metal corrosion rate occurring in the tested system as follows:

Fp=[Ba*Bc/2.303(Ba+Bc)]/Rp

In the formula: Fp - corrosion rate, Ki - conversion factor, Rp - polarization resistance,
Ba, Bc - Tafel slope of cathodic and anodic curves.
