Functional Features
Capable of detecting concentrations, absorbance, and transmittance of nearly a hundred parameters in water quality.
Ability to store, print, query, and upload concentration values to a computer.
Wavelength Selection: allows automatic wavelength selection during sample measurement, eliminating the need for manual calibration.
Users can add and store custom calibration curves in addition to factory presets. Measurement methods include linear and piecewise linear (segmented) methods,
enhancing accuracy for parameters with non-linear responses.
Built-in calibration function for self-calibration during operation, effectively reducing long-term drift errors.
Features one-touch recovery for restoring factory and user-defined curve data in case of accidental loss. Also includes automatic backup of calibration curves and data records to prevent loss.
Incorporates startup and system password settings for enhanced security.
Utilizes a user-friendly 5-inch color touchscreen for intuitive operation.
Offers 16 levels of light intensity adjustment to address measurement range expansion issues caused by signal strength variability.
Supports bilingual operation with switchable Chinese and English language settings.
Capable of storing 250 factory curves, add 3500 user curves, and store up to 100,000 records.
Allows comprehensive curve querying, including equation retrieval and details on standard substance values, absorbance, calibration time, and personnel ID.
Supports single-item or page printing during record queries.
Includes features like timed reminders, automatic shutdown after digestion, and secondary protection mechanisms to ensure safety during high-temperature operations.
