1Immersion turbidity sensor

Overview Overview:

The TBD-99 immersion turbidity sensor has a compact appearance, rich functions, and a more convenient use process. Using transmitted light detection technology to indicate the turbidity of water based on the intensity of transmitted light. It can automatically compensate for voltage fluctuations, device aging, temperature changes, and changes in water sample color to provide long-term reliable measurement results. Mainly used for turbidity detection of pre filtration, post filtration, sedimentation, and factory water in waterworks; Pipeline water quality monitoring, industrial process water quality monitoring, monitoring of circulating cooling water, carbon filter effluent, membrane filtration effluent, etc; Water quality monitoring of sewage treatment inlet, outlet, reservoir, well, etc; Online turbidity monitoring in industries such as electricity, purified water, beverages, alcohol production, and pharmaceuticals.

2、 Circulating turbidity sensor

Product Overview:

The product adopts the principle of detecting scattered light in the 90 ° direction. According to EN27027 and ISO7027 standards, 860nm infrared light is used as the light source, which is not affected by the chromaticity of the sample. The scattering degree of light generated by insoluble particles suspended in water is measured online to quantitatively measure suspended particles. Mainly used for turbidity detection of pre filtration, post filtration, sedimentation, and factory water in waterworks; Pipeline water quality monitoring, industrial process water quality monitoring, monitoring of circulating cooling water, carbon filter effluent, membrane filtration effluent, etc; Water quality monitoring of sewage treatment inlet, outlet, reservoir, well, etc; Online turbidity monitoring in industries such as electricity, purified water, beverages, alcohol production, and pharmaceuticals.

Product features:

★ Standard 90 degree scattered light measurement technology, compliant with USEPA method 180.1 specification, providing reliable measurement results;
★ Low range flow formula: Integrated installation design, removable and washable defoamer, easy maintenance;
★ High range flow formula: Integrated installation surface scattering method design, avoiding direct contact between the detector and sewage, greatly reducing maintenance costs;
★ Built in voltage stabilizing and defoaming device to eliminate the influence of bubbles on the measured values;
★ Adopting infrared laser scattering mode, it has high sensitivity, stability, reliability, and fast response speed in the low turbidity range;
