Turbidity Sensor
Formulation Formula: A=K*B/C
■ A: Absorb quantity (ml)
■ B: Concentration of the solution required to be formulated (NTU)
■ C: Proto-standard liquid concentration (NTU)
■ K: Total amount of preparation (ml)
Example: 10 NTU turbidity standard solution configuration method
Dissolve 2.5ml (The concentration was 400 NTU) solution transfer to a 100ml volumetric flask, add deionized water or
distilled water and dilute to a 100ml scale line, shake well and use to measure.

Sensor Calibration

1. Sensor Read
Connect the digital turbidity sensor to the computer through the Modbus RS 485, and open the Modbus debugging
software: mbpoll.exe, Set the address 1,9600, N, 8,1, then select "Float" at "Display", as shown in the figure below; where
00002 shows the temperature value, that is, the ambient temperature of the turbidity sensor is 14.5
turbidity value, where the aqueous solution in which the turbidity sensor is located is 20.7 NTU.
2. Manual Start Brush
As shown in the figure below, after connecting the turbidity sensor, select 06 function code in the communication software,
Address input: 20, Value input 66, click Send, to observe the sensor brush start.
