Portable Dissolved Oxygen Meter

I. Product Overview

The portable dissolved oxygen analyzer enables rapid on-site testing of two core water quality parameters - dissolved oxygen (DO) and temperature (Temperature). The device is equipped with BeiDou positioning, which simultaneously records sampling point information for convenient data traceability. The whole unit is waterproof, lightweight and easy to carry, simple to operate, and supports Chinese/English switching, meeting the needs of various field water and industrial on-site testing scenarios at home and abroad.

II. Applications

1. Ecological environment: investigation of black-odorous water bodies in rivers, lakes and reservoirs, water quality patrol of outfalls and on-site evidence collection;

2. Aquaculture: dissolved oxygen monitoring and hypoxia early-warning for freshwater and seawater aquaculture, cage culture and hatchery bases;

3. Wastewater treatment: process control and discharge compliance testing of biochemical tanks (aeration tanks) in municipal and industrial wastewater treatment plants;

4. Research & teaching: water ecological protection investigation, aquatic organism research and field sampling analysis by colleges and research institutes;

5. Overseas projects: survey and water quality assessment for overseas environmental water utilities, aquaculture and water environment treatment projects.

III. Product Features

1. The whole instrument achieves IP67 waterproof and dustproof rating; outdoor testing is immune to water vapor, rain splashing and short-time immersion;

2. Adopts digital electrodes with automatic recognition upon connection, and supports temperature compensation and air-pressure compensation, effectively avoiding the influence of ambient temperature and improving measurement accuracy and stability;

3. Built-in 23680 mW/h large-capacity lithium battery, delivering a battery life of more than 24 hours;

4. Standard large-capacity storage on the main unit, capable of storing more than 200,000 sets of test data;

5. ★ Equipped with user-switchable BeiDou positioning; positioning information is stored and printed synchronously for convenient sampling traceability;

6. ★ Supports USB data export, WIFI remote firmware upgrade, and Bluetooth connection to an external printer;

7. Equipped with multiple reading modes - automatic, timed, interval and manual - adapting to various testing conditions;

8. ★ Electrodes are fitted with push-pull self-locking aviation connectors featuring a fool-proof structure for quick assembly and disassembly, with a sealing structure matching the protection rating of the whole instrument;

9. ★ The magnetic interface handles both charging and data transmission, reducing wear from repeated plugging and unplugging, enhancing waterproof and dustproof performance, and extending the service life of the interface;

10. Intelligent power-saving management: configurable sleep and auto-shutdown, with low-battery reminders and charging status display;

11. ★ Supports user-defined limit values; when data exceeds the limit, a synchronous sound alarm and red-highlighted display value are triggered, effectively preventing data omission;

12. ★ 4-inch high-definition color LCD screen, supporting backlight adjustment and one-touch manual switching of the Chinese/English system interface;

13. Detachable, tightening wrist strap for convenience and handheld comfort;

14. Strong overall compatibility: various suitable electrodes can be flexibly selected according to testing requirements.
