　　2. Introduction to Online Turbidity Meter Products

　　Online turbidity refers to the degree of obstruction caused by suspended solids in water to the transmission of light. Water containing soil, silt, fine organic matter, and other microorganisms and colloids can cause turbidity in the water. The light waves emitted by the transmitter on the sensor are absorbed, reflected, and scattered by the measured object during transmission. Some of the transmitted light can be directed towards the detector in the 180 ° direction, while some of the scattered light can be directed towards the detector in the 90 ° direction. The intensity of light received by detectors in the 180 ° and 90 ° directions is related to the turbidity of the measured wastewater. Therefore, by measuring the intensity of transmitted and scattered light, the turbidity of the wastewater can be calculated.

　　Key Features:

　　The internal structure effectively eliminates water bubbles, improves measurement accuracy and stability (flow type).

　　By disassembling the water outlet connector module, the optical path lens and the inner wall of the flow channel can be cleaned, making maintenance more convenient (flow type).

　　◇ Internal upgrade of the sensor effectively prevents moisture and dust accumulation in the internal circuit, avoiding damage to the internal circuit (flow type).

　　Built in zero position adjustment potentiometer, sensor can be mechanically zeroed (flow-through).

　　The sensor housing is made of 316L stainless steel, which has good corrosion resistance (submerged type).

　　The turbidity sensor is not affected by sample flow rate and pressure (submerged type).

　　The infrared light waves emitted by the transmitter on the sensor use a stable invisible near monochromatic infrared light source, which avoids the interference of chromaticity in the liquid and visible light from the outside on the sensor measurement.

　　The sensor uses a quartz glass lens with extremely high transmittance on the optical path, which makes the emission and reception of infrared light waves more stable; And built-in photometric compensation to improve measurement accuracy.

　　The instrument adopts a brand new waterproof, dustproof, and moisture-proof shell (IP65) technology, with a surface painting process and a generous appearance.

　　◇ Wide range, stable measurement, high accuracy, good reproducibility, and strong anti-interference ability.

　　Communication function: Equipped with RS-485 communication interface (partially compatible with MODBUS protocol) (optional); Optoelectronic isolation with 4-20 mA current output, the corresponding value can be set arbitrarily.

　　◇ The function of setting the hysteresis value arbitrarily avoids frequent actions of the switch relay, and has the function of setting the switch value to turn off and off.

　　◇ Adopting two-point calibration method, the instrument range can be modified.

　　Watchdog function: Ensure that the instrument panel does not crash.

　　◇ Power failure protection>10 years.
