Based on the characteristics of global water quality and monitoring standards, combined with our own technical advantages, using the building block configuration concept, we have ingeniously integrated the electrode method with microcomputer photometric measurement principles to launch the latest ET9919 multi-parameter mobile laboratory series. This series not only meets the requirements for water quality testing in various outdoor environments but is also suitable for rapid water quality detection during emergencies and routine water parameter measurements in laboratories, allowing users to meet their water testing needs with minimal investment.
The spectrophotometer built into this system features over 120 test method applications and electrode-based measurements, enabling it to measure more than 130 important water quality parameters. These are widely applied in water quality monitoring across industries such as industrial, municipal, environmental protection, and education sectors.
Key Features:
- Rapid measurement of various water quality parameters with user-friendly operations.
- Large capacity storage for ion concentration and turbidity data.
- RS232 and USB data interfaces allow for storing and managing data which can be transmitted to a computer for further analysis, printing, etc.
- Suitable for comprehensive water quality analysis in the field, at production sites, and in laboratories.
Specifications:
A. Photometric determination uses a wide range of continuous wavelengths, automatically selecting wavelength based on the measurement item;
B. Microprocessor patented technology, ORP57 type oxidation-reduction/temperature tester, user-friendly design with large screen display, flowchart graphic display, simple operation;
C. Conventional or fast measurement of pH, conductivity, dissolved oxygen, turbidity, COD, TOC, total chromium, total phosphorus, total nitrogen, ammonia nitrogen, fluoride, iron, copper, phosphate, sulfate, nitrate, and more than 130 other important parameters;
D. Large capacity data storage function, routinely storing 200 to 1000 data sets (limited to ion concentration and turbidity measurement values);
E. Use of pre-prepared reagents, GTOP-300B type intelligent lighted incubator (seed germination box), some reagent shelf life can reach 5-10 years;
F. Convenient connection to computers for real-time printing or data management (limited to ion concentration and turbidity measurement values);
G. Portable packaging, waterproof and shockproof design, economical consumables, suitable for field and laboratory analysis and testing.
