Page 3: Applications
1. Applications Model BMET-703 turbidimeter is used to measure the light scattering or attenuation generated by the insoluble particulate matter which is suspended in water (or clear liquid). The instrument can quantitatively characterize the content of the suspended particulate matter. The instrument can be widely used in many field and industries, such as water, food, chemical, power, metallurgy and... -

4. Working Principles The basic principle of a turbidimeter is when light goes through the vial containing the suspension sample, the ratio between the generated 90º scattered light signal and the sum of the forward transmitted light and forward scattered light changes in accordance with the figure of turbidity, namely: The optical and circuit systems both are designed according to the above principle. -

6. Circuit System The tungsten halogen lamp is supplied by the voltage regulator circuit and produces stable light source. Different parts of signals are respectively received the corresponding receiver, after going through the amplifier, it enters A/D converter. The digital signal generated by A/D converter enters the SCM system. After being processed and calculated, it will show on the LCD screen. -

methods, and the purity should be greater than 99%. Hexamethylenetetramine (C6H12N4): AR, purity required analysis by GB 1400-78 standard methods, and the purity should be greater than 99%. Incubator (or water bath): volume can accommodate 200ml volumetric flask, thermostat 25℃±1℃, and can run continuously for more than 24hrs. - Page 9 c) Repeat Step 2 and calibrate following points in order, 20NTU, 200NTU, 500NTU, 1000NTU, and 2000NTU (for Model WGZ-200, only 2NTU, 20NTU and 200NTU are to be calibrated). d) As all points are finished with calibration, go back to the main interface, and press system settings or saved button to exit the calibration.
