AI Technical Summary

Technical Problem

Existing water quality testing pens suffer from insufficient accuracy due to their probes being too close together, making it impossible to accurately detect parameters such as total organic carbon (TOC) and chemical oxygen demand (COD) in water.

Method used

The water quality testing pen has an independent testing area inside its protective cap. The temperature detection probe, TDS electrode detection probe, and ultraviolet detection probe are placed in different testing areas, and the ultraviolet emitting probe and receiving probe are set up accordingly to reduce detection interference between probes.

Benefits of technology

It improves the accuracy of water quality testing, enabling independent detection of parameters such as water temperature, TDS, TOC, and COD, while reducing detection interference between probes.

Abstract

The detection probe arrangement structure comprises a pen body with an opening in the lower end, the lower end of the pen body is connected with a protective cover, and a protective cover through hole for water to enter is formed in the side face of the protective cover. A temperature detection probe, two TDS electrode detection probes, an ultraviolet emission probe and an ultraviolet receiving probe are arranged on the connecting end face of the protective cover, a first detection area, a second detection area and a third detection area are arranged in the protective cover, and the temperature detection probe detects in the first detection area. The two TDS electrode detection probes are arranged in the second detection area, the ultraviolet transmitting probe and the ultraviolet receiving probe are arranged in the third detection area, and the transmitting end of the ultraviolet transmitting probe and the receiving end of the ultraviolet receiving probe are oppositely arranged, so that the detection of TOC (Total Organic Carbon) and COD (Chemical Oxygen Demand) of the water body is realized. And meanwhile, each detection probe is respectively arranged in an independent detection area, so that the mutual detection interference is reduced.
