product key technologies
Equipped with a unified minimalist chassis layout, the portable multi-parameter calcium ion concentration meter measuring apparatus boasts slim build dimensions, negligible weight and a hand-contoured holding section for convenient carrying and one-handed manipulation. Customized for movable fast analytical work, this gear performs real-time surveillance of calcium ion markers contained within diverse liquid test media. It matches perfectly with off-station measurement assignments such as outdoor field sampling rounds, plant periodic inspection and impromptu water condition assessment. Without being bound to the spatial constraints of stationary lab detectors, it delivers highly adaptable and hassle-free measurement performan
Quantitative detection of calcium species is realized via ion selective electrode analytical techniques on this handheld tester. The vital sensing assembly consists of a calcium targeted electrode integrated with a reactive film featuring exclusive responsiveness to calcium charged particles. Submerging the electrode assembly inside specimen fluid creates an electrical voltage gradient over the thin sensing barrier. Such electrical variance holds a logarithmic linkage to calcium ion effective concentration, complying with the Nernst mathematical relation. A ultra-precise voltage detection unit records the generated electrical signal, then the equipment carries out automatic computation of calcium ion molar concentration and ionic activity.
Key Features & Applications
This instrument enjoys wide industry compatibility, meeting the testing demands of university teaching experiments, physicochemical research in scientific institutions, water quality management in power and water supply industries, petrochemical production, and microelectronics precision manufacturing. With stable performance and excellent measurement accuracy, it precisely determines calcium ion concentration in various water bodies, providing reliable data support for water quality analysis. In addition, it features strong sample compatibility, enabling physicochemical analysis of natural environmental water, laboratory purified water, power plant circulating process water, and industrial production wastewater.
