Portable Multi-parameter Water Quality Analyzer

I. Product Overview

The portable multi-parameter water quality analyser integrates two rapid detection principles in one instrument — spectrophotometry and the electrode method — in a high-strength PVC engineering plastic carrying case with an integrated digestion and measurement design. The digestion module has dual temperature zones, while the measurement section supports both 360° rotating colorimetric tube measurement and cuvette measurement. It features an Android smart operating system, an 8-inch high-definition LCD touch screen, fibre-optic detection technology, an imported light source and a built-in high-capacity lithium battery.

II. Applications

Determination of multiple water pollutants in domestic sewage, industrial wastewater, groundwater and surface water; water quality analysis in testing laboratories, municipal authorities, wastewater treatment plants, environmental monitoring stations, universities and research institutes, power plants, centres for disease control, papermaking and electroplating, aquaculture, biopharmaceuticals, petrochemicals, coal, metallurgy, textiles and food industries.

III. Detection Items

Spectrophotometric module: chemical oxygen demand (COD). Sensor module: pH, ORP, dissolved oxygen (fluorescence), residual chlorine (constant-potential), conductivity, salinity, ozone, turbidity, hardness, suspended solids, sludge concentration, COD, ammonia nitrogen, chlorophyll, blue-green algae, oil in water and CDOM (chromophoric dissolved organic matter) sensors — several dozen indicators in total.

IV. Key Features

1. Android smart system version 7.1.1 for a smoother interactive experience, faster response and greater stability.

2. Dual colorimetric system supporting both pre-made tube colorimetry and cuvette colorimetry.

3. The tube measurement section uses a 360° precision rotating device that effectively guarantees accuracy and improves stability tenfold.

4. Built-in dual-zone 8-position digester with independent left and right temperature zones for rapid digestion of COD, total phosphorus and total nitrogen.

5. Portable all-in-one design with a built-in high-capacity lithium battery: digestion and measurement can both be completed in the field.

6. Built-in thermal printer with automatic and batch printing, editable print content and QR code support.

7. Wi-Fi, 4G and RJ45 wired network connectivity for data upload.

8. Supplied with a data cloud platform that receives measurement data for online storage and short- and long-term trend analysis.

9. Users can build their own standard curves, with custom calibration of coefficient curves and sample curves.

10. Built-in sensor measurement module accepts four sensors of different parameters at the same time — plug in and measure, with direct concentration readout.

11. Sensor measurements support timed or manual storage, and the data can be printed.

12. Built-in instructional videos: users can follow the demonstration while operating, which makes learning much easier.

13. Detection, digestion and sensor measurement can run simultaneously, greatly improving efficiency.

14. Detection items can be customised to user requirements.

15. Supplied with factory pre-made reagents and consumables: no repeated pipetting or concentrated sulfuric acid preparation is needed — simply add the water sample to the tube.

16. User-friendly pin-to-top function places frequently used items at the top of the project list.

17. GPS positioning shows the longitude, latitude and landmark of the measuring point in real time; the position is saved with the data and can be uploaded to the cloud platform.
