Product Description
1. Equipped with a 4.3-inch color LCD screen and an intuitive GUI graphical navigation
system, the device features a membrane keypad with thin, soft, and highly protective keys
that can withstand over 1 million presses. The keypad is rich in functions, intuitive, and easy
to use, providing clear guidance for effortless operation.
2. The instrument is compact and lightweight, easily operable with one hand. It can measure
various routine water quality parameters such as COD, ammonia nitrogen, total phosphorus,
total nitrogen, turbidity, chromaticity, suspended solids, and heavy metal ions. Concentration
readings are displayed directly without conversion, ensuring more accurate measurement
results.
3. Features large-capacity data storage, capable of storing over 5,000 test results, allowing
users to conveniently review data at any time.4. Incorporates a unique high-precision optical filtering system for greater stability and
enhanced measurement accuracy.
5. Built-in high-capacity lithium battery with an efficient charging system, providing up to
10 hours of battery life.
6. Uses a cold light source with narrowband interference technology, offering a light source
lifespan of up to 100,000 hours.
7. Powered by the latest T5L ultra-compact chip, delivering faster response and larger
memory capacity-up to 500MB.
8. Supports 9-point calibration curves. Users can customize calibration curves according to
measurement needs, meeting the diverse requirements of different users.
9. Compatible with Lab-yy pre-packaged reagents, eliminating the need for manual reagent
preparation. This saves time, reduces operational technical requirements, and greatly
improves efficiency.
10. All test items comply with national industry standards: GB/T 5750.11-2023.
