Portable 5-parameter Water Quality Meter

I. Product Overview

The portable five-parameter water quality analyzer enables rapid on-site testing of five core parameters - water pH, dissolved oxygen (DO), conductivity (Cond), turbidity (Turbidity) and temperature (Temperature). It 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 testing scenarios at home and abroad.

II. Applications

1. Ecological environment: routine water quality patrol of rivers, lakes, reservoirs, groundwater and outfalls, surface-water environmental quality assessment and on-site evidence collection;

2. Industry & water utilities: source-water monitoring for waterworks, comprehensive influent/effluent water quality monitoring for wastewater treatment plants, and routine inspection of industrial wastewater discharge;

3. Aquaculture & marine: water quality baseline environment and eutrophication index testing in freshwater and seawater aquaculture, offshore and tidal-flat waters;

4. Research & teaching: field investigation and sampling of water ecological protection, water environment evolution and routine water quality indicators by colleges and research institutes;

5. Overseas projects: routine water quality measurement and survey projects for overseas water conservancy hubs, integrated water management and environmental protection operation & maintenance.

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.
