Functional Features
The instrument can detect the concentration, absorbance, and transmittance of nearly a hundred types of water quality parameters, and it can store, print, query, and upload concentration values to a computer.
The instrument is equipped with an 8-hole dual-temperature-zone digester, featuring a 4+4 dual-temperature-zone design with independent temperature control, suitable for multi-parameter and batch project testing.
The integration of electrode method and spectrophotometry meets the testing requirements for multiple parameters using electrochemical and colorimetric methods.
The triple-proof casing (dustproof, waterproof, and impact-resistant) integrates all necessary equipment, covering all outdoor water quality testing needs, with convenient operation and portability.
No worries about battery life for outdoor testing: continuous dual-temperature digestion can last up to 3 hours, supporting simultaneous digestion of multiple parameters, with the main unit's battery life reaching up to 48 hours.
The instrument can store 200 factory calibration curves, 3,000 user-defined curves, and up to 99,999 records.
The LED light source responds quickly, allowing the instrument to be ready for use immediately, with stable and reliable measurement values.
A one-key recovery function is available to restore factory and user calibration curves and data records in case of accidental loss.
The instrument backs up user-calibrated curves and data records, allowing for recovery in case of accidental loss.
The instrument features a large color touchscreen with a user-friendly interface and an operation guide to explain various functions.
Personalized customization is available, with detectable parameters and ranges that can be upgraded according to user needs.
The instrument has various safety measures, including password settings for startup and system configuration to prevent accidental changes by unauthorized personnel.
The light intensity is adjustable in 16 levels, which can effectively solve the problem of measurement range expansion caused by strong or weak signals.
Optical calibration is supported to ensure the precision of optical components, enhancing the instrument's accuracy, stability, and service life.
Up to 100,000 records can be stored (including parameter names, concentrations, units, detection times, and operator IDs), with the option to print individual or page records during query.
Curve queries are available, allowing users to view not only the calibration equations but also the standard values and corresponding absorbances of each standard substance used during calibration, as well as the calibration time and operator ID, fully reproducing the calibration state.
The system has bilingual functionality, allowing users to switch between Chinese and English.
The instrument is equipped with a USB port for data transfer to a computer.
