Product Description Product DescriptionInstrument Features:Equipped with a 7-inch high-resolution (1024×600) capacitive color touch screen and a UI-based navigation operation interface. It offers high sensitivity, comprehensive parameter display, intuitive visuals, and user-friendly operation. The main unit housing is made of PEEK material, which is heat-resistant, corrosion-resistant, and anti-aging.Built-in ARM 32-bit microprocessor chip, utilizing digital filtering and differential techniques to intelligently improve response speed and measurement accuracy. The circuit board adopts SMT surface-mount technology for enhanced manufacturing reliability.Compliant with international GLP standards, the instrument features automatic calibration, automatic temperature compensation, data storage, USB output, real-time clock display, wireless printing, customizable settings, and self-diagnosis functions.Dual-language interface (Chinese and English) is built-in. User-friendly design includes adjustable screen brightness and temperature unit switching between °C and °F.Large-capacity internal memory stores up to 500 sets of measurement data. Data can be transferred via USB flash drive and opened using standard office software like Excel, greatly facilitating data editing and analysis.USB interface supports easy data export and PC viewing. Compatible with custom software for data storage and management when connected to a computer.The newly designed polarographic DO (Dissolved Oxygen) electrode can simultaneously measure temperature and dissolved oxygen. Comes with a dedicated DO electrode calibration sleeve, and electrode polarization takes only 3-5 minutes.Uses a modular membrane cap; replacing the sensitive membrane is as easy as screwing a new cap onto the electrode-extremely convenient.Dissolved oxygen measurement mode includes automatic temperature, salinity, and barometric pressure compensation.Intelligent electrode status detection ensures accurate usage by the user.Optional Bluetooth function allows wireless connection to a Bluetooth printer or mobile app.Powered by a rechargeable lithium battery, supporting both power adapter and mobile power charging.Designed to meet IP54 dust and splash protection standards.
