Online industrial conductivity meterCompared to laboratory conductivity meters, there are several differences:
1. Fewer buttons
Generally speaking, online industrial conductivity meters only have a few buttons, and long and short presses of the same button have different effects, so the detection of functional buttons is particularly important.
2. Complex operating procedures
The operation of laboratory conductivity meters is relatively simple, and some laboratory conductivity meters can be directly operated and measured without instructions. Although the online industrial conductivity meter has few buttons, its functions are complex. Some conductivity meters have more than 10 operation subdirectories. It is necessary to fully and proficiently operate the instrument to avoid misoperation and complete shutdown of the production line. Therefore, the manual for the online industrial conductivity meter equipped with this model is also *.
3. Chaotic wiring
Online industrial conductivity meterThe wiring behind a laboratory conductivity meter is usually much more complex than that of a laboratory conductivity meter. Generally, the wiring behind a laboratory conductivity meter consists of a three core electrode socket, a temperature socket, and a power plug interface. Online industrial conductivity meters generally have 4-5 connection terminals for electrode wiring ports, 2 connection terminals for temperature, 2-3 connection terminals for power supply, and 2 output terminals for output current, making them relatively complex. Therefore, it is necessary to check and record the wiring of the conductivity meter for industrial control to avoid unnecessary trouble caused by the inability to recover after calibration is completed.
4. Power hazard
There are generally two types of power sources for online industrial conductivity meters: one is 24V DC input; The other type is 220V AC input, so compared to laboratory conductivity meters that only operate under 9V DC input, online industrial conductivity meters are more dangerous. It is necessary to check the power connection of online industrial conductivity meters to prevent electric shock accidents.
5. Chaotic sensors
Laboratory conductivity meters generally use platinum black electrodes and bright electrodesOnline industrial conductivity meterThe sensor models are very diverse, including electrode sensors, inductive sensors, and ultrasonic sensors. For electrode sensors, they are divided into stainless steel sensors for pure water use and ordinary sensors for general measurement according to their applications. According to their properties, they can be divided into two electrode sensors and four electrode sensors. For the measurement of different types of liquids, selecting the appropriate sensor plays a very important role in measuring the conductivity of the solution.
