Portable Ammonia Nitrogen Meter

I. Product Overview

The portable ammonia nitrogen analyzer enables rapid on-site testing of core parameters - ammonia nitrogen (Ammonia Nitrogen) in water, water pH and temperature (Temperature) - and 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 testing scenarios at home and abroad.

II. Applications

1. Ecological environment: patrol and on-site evidence collection for ammonia nitrogen pollution in rivers, lakes, reservoirs and outfalls;

2. Water conservancy & hydrology: river discharge surveys, reservoir water quality monitoring, and general surveys of black-odorous water bodies and groundwater;

3. Aquaculture & marine: ammonia nitrogen toxicity and water quality testing in freshwater and seawater aquaculture, offshore and tidal-flat waters;

4. Research & teaching: field water nitrogen-cycle and eutrophication investigation and sampling by colleges and research institutes;

5. Overseas projects: ammonia nitrogen monitoring and survey projects for overseas water conservancy, aquaculture and water-environment 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.
