The TW1010 turbid meter is used to measure the turbidity of solutions and the chemical reactions that can cause turbid effects.
Principle
Turbid meter is a sensor used to measure turbidity of solution. White light emitting diodes and silicon photocell are respectively arranged on the two sides of the cuvette, and the turbidity of the solution is known by measuring the intensity of the scattered light. Turbid meter can measure the speed of chemical reaction, and measure the rate of reaction through the speed of turbidity in solution. The colorimetric dish matched with the sensor is of optical grade quartz material, its volume is 4.1cm3.
The light receiver is located in a position perpendicular to the emitted light. It measures the amount of light scattered by the suspended particles in the sample. By comparison with the standard solution, the value is converted to the turbidity value. Because the scattering light intensity is proportional to the suspended substance concentration when the particle concentration is low, this is the principle that the turbidity sensor can work normally. Before using the standard turbidity value solution, the sensor should be calibrated first, then the concentration of the suspended substance is detected by measuring the scattering light intensity, and the black background is measured. The quantity and sensitivity are also high.
Specification
| Measuring Range | 0~400NTU |
| Resolution | 0.1NTU |
Usage
- Turbid meter is directly connected to the computer according to the boot button or USB line. If the numerical deviation is large when it is used for the first time, it can be reset.
- After the 2. turbid meter is connected to the computer, the software can be opened and the "Multi USB" collection mode is selected. If the Bluetooth connection is connected, the "Wireless" collection mode is selected.
- Low power reminding: USB power is not inserted and when the battery is low, the word "Lo" will flicker on the screen; USB power is inserted, no matter whether the battery is low or not.
- After measuring the low power state, the system will have errors in measuring data and cannot be used as a basis for measurement.
Note
- When the measurement value is inaccurate, users need to reset operation.
- When the system indicates low power state, there will be errors in measuring data, which can not be used as a basis for measurement.
Typical experiments
1. The turbidimetric comparison of different water quality;
2. To explore the rate of reaction between sodium thiosulfate and acid.
