300B Type Water Quality Meter, Sewage Detection, Photoelectric Colorimetry (CAT#: STEM-GLE-1696-LGH)

Portable, AC and DC power supply, with low voltage indication and automatic shutdown function.
Microcomputer low-power configuration, touch keyboard, Chinese operation interface. Equipped with self-diagnostic information prompts.
The standard working curve in memory can be used directly, and 1-7 points can be quickly and arbitrarily selected for automatic correction.
Independent research and development of rapid determination reagents to ensure long-term stable and low-cost supply, effectively reduce user workload and sample testing costs, and meet national standards.
