By measuring the intensity change of light before and after passing through the material, the instrument calculates the transmittance, thereby evaluating the optical properties of the material, and can more accurately and quickly detect the particulate matter content in the wastewater, so as to adjust the parameters of the sewage treatment in time according to the particulate matter in the wastewater. When the staff needs to sample the wastewater without stirring, the user only needs to fix the detection test tube 210 inside the fixing claw 29, and then press the pressure rod 214 to immerse the wastewater in the detection test tube 210, so as to sample the wastewater, thereby increasing the flexibility and practicality of the device.
