Chongqing Googol ChangjiangResearch Institute Co., Ltd.
About
Googolwater, operating as Chongqing Googol Changjiang Research Institute, was established in 2016 in Yongchuan, Chongqing as a subsidiary of publicly listed Googol Technology (Stock: 301510) leveraging academic resources from the Hong Kong University of Science and Technology. The company manufactures reagent-free optical and electrochemical water quality sensors with over 20,000 sensors deployed across 20+ countries. Their flagship WQS-F series uses UV-Vis absorption spectroscopy across a 200–800 nm wavelength range with AI-driven algorithms to simultaneously derive COD, TOC, DOC, BOD, turbidity, TSS, nitrate, nitrite, color, and ozone without chemical reagents. The WQS-F is available in multiple light-path configurations (2 mm, 5 mm, 15 mm, and adjustable 40–150 mm) with IP68-rated AISI 316L housings, automatic self-cleaning brushes, and 10-second measurement cycles. The sensor line also includes the WQS-M (advanced resolution) and WQS-D (basic resolution) multi-parameter optical sensors, the WQS-TUR dedicated turbidity sensor, and electrode sensors for dissolved oxygen (WQS-DO), ammonia nitrogen (WQS-NH3), pH (WQS-pH), conductivity (WQS-EC), ORP (WQS-ORP), free chlorine (WQS-Cl-C), and total chlorine (WQS-Cl-T). The WQS-Server cloud platform enables remote device management and monitoring data integration. The institute holds 32 patents and certifications including ISO 9001, CE (TUV), RoHS (SGS), and CQC.
