1.IntroductionÂ
This Portable Dissolved Oxygen Analyzer uses the principle of fluorescence method to monitor dissolved oxygen data. Compared with the traditional electrode method, it has the characteristics of accurate and stable monitoring data, strong resistance to environmental interference, fast measurement speed, and long service life. In addition, the fluorescent film of this detector breaks the foreign monopoly technology and is a hard fluorescent film developed domestically. It also has the characteristics of scratch resistance and not easy to fall off.
2.Features
- The fluorescent membrane of the dissolved oxygen probe is replaceable.
- One-touch measurement, press the measurement button to observe the data at any time.
- Night backlight, clear and visible at night.
- Long standby time, the device automatically shuts down after the test is completed.
- The display screen uses an ink screen, the observation experience of a paper book, eye protection without glare, strong light is clearly visible
