On-line conductivity meter

Online conductivity meters are also called digital display conductivity meters and industrial online conductivity meters. Online conductivity meters have strong environmental adaptability, strong anti-interference ability, good stability and reliable operation. They have analog output, digital communication, upper and lower limits. Alarm and control functions, etc.

1. Online conductivity meter controller parameters

Product size: Instrument appearance size: 96*96*110mm; opening size: 92*92mm.

Power consumption: DC24V≤1.6w; AC220V≤15w

Power supply voltage: DC24V/AC220V optional before leaving the factory.

Protection level: IP54

Instrument weight: controller ≤0.6kg.

Working conditions: Ambient temperature: -20~60℃ Relative humidity: <85%.

Overall appearance: 128*64 dot matrix LCD display, with operation buttons.

Display content: current date, time, measured value, current measured temperature, output current value

Function switching: turbidity measurement mode, dissolved oxygen saturation measurement mode, dissolved oxygen concentration measurement mode, ammonia nitrogen measurement mode, and COD measurement mode can be selected by pressing the button

Time display: The controller has a built-in clock chip that can display the current time.

Data storage: The built-in memory chip of the instrument can save the historical data of the past three days for easy search by the user.

Anti-interference ability: Using the latest devices, the impedance is as high as Ω; the current output adopts photoelectric coupling isolation technology, which has strong anti-interference ability and realizes remote transmission. Has good electromagnetic compatibility.

Communication interface: RS485 and 4-20ma signals are output simultaneously.

Watchdog design: industrial control watchdog: ensure that the instrument will not crash.

Relay settings: By default, it has two relay outputs, a high point and low point alarm relay and a low point alarm relay. The high and low alarm values of the device can be set, and the high and low alarm relay pull-in and cut-off values can be set respectively.

Relay load capacity: AC220V, 3A;

Range setting: You can set the zero range and full range corresponding to the device's current output.

Password protection: The device buttons are equipped with password protection function to prevent non-administrators from tampering with parameters.

Backlight design: When the light is relatively dark, workers can still clearly view the temperature data/time/date, etc. on the device. The backlight time can be set to stay on or how long it will take to turn off when there is no operation and enter the power-saving mode.

Buzzer setting: The buzzer alarm function can be turned on and off manually.

Button calibration: The time, real-time values of current temperature and water quality can be calibrated through the buttons.
