Cable length and compatibility - Cable length: about 300 cm (approximately 3 meters) for flexible placement in tanks, benches, or workstations. - Connector: BNC connector; compact, lightweight, and portable. Suitable for most pH meters and controllers with BNC connectors. Applications and use cases - Aquariums: monitor and manage pH (and support correct water chemistry) to maintain healthy aquatic environments. - Hydroponics: ensure appropriate pH in nutrient solutions to optimize plant growth and nutrient uptake. - Laboratories and education: useful for students and professionals in water quality testing and analysis, supporting accurate pH assessment and related experiments. - General water quality monitoring: helps achieve the correct pH and temperature levels in water quality monitoring and analysis. Function and measurement - Function: pH meter is an electronic device used for measuring pH, which is the concentration of hydrogen ions in an aqueous solution or the activity of the hydrogen ions in an aqueous solution. Medium compatibility - Medium: designed to work in liquids; some probes are used to measure the pH of semi-solid substances. Notes on compatibility - BNC: Compact, lightweight, and portable; suitable for most pH meters and controllers with BNC connectors.
