ZC1010 turbidimeter is a sensor used to measure the turbidity of solution and turbidity effect of chemical reaction.
Working principle
The Turbidimeter is used to measure the turbidity of the solution. A white light emitting diode and a silicon light cell are placed on two sides of the cuvette respectively. By measuring the illumination of scattered light, the turbidity of the solution can be measured. Turbidimeter can measure chemical reaction speed which can be used to measure the changing speed of turbidity in solution. Sensor's cuvette is made by optical quartz. Its volume is 4.1cm3.
Light receiver is perpendicular to the light. It measures the amount of light scattered by particles suspended in the sample solution. Compare it with the standard solution. The value will be converted to turbidity. Because the illumination of the scattered light is direct proportional to the concentration of the suspended particles when the particle concentration is low. This is the working principle of turbidity sensor which can work normally. The sensor should be calibrated with standard turbidity solution before using. Concentrations of the suspended particles are evaluated by measuring the scattered light illumination.
The sensitivity is higher when measuring in black background.
Specification
| Range | 0~400NTU |
| Resolution | 0.1NTU |
Usage
Connect the sensor to computer using USB cable. Calibrate it when using it at first time if error is obvious.
After connecting to computer, open the software and set the acquisition mode to 'Mini USB'.
Make sure that there is no waterlogging remains on the outer surface of cuvette.
Short press once and the mode will become 'calibration 0.0'. Short press again and mode will become 'calibration 400'. Short press one more time will make it becoming normal measurement mode.
Hold more than 3s to exit the calibration status.
Notes
- When the Turbidimeter is under calibrating (numerical blinking), it will automatically back to an uncalibrated state if there is no operation in 5 minutes.
- Make sure that there is no waterlogging remains on the outer surface of cuvette.
The sensitivity is higher when measuring in black background.
