Portable Multi-parameter Water Quality Tester

I. Product Overview

The portable multi-parameter water quality analyser adopts a high-strength PVC engineering plastic carrying case with an integrated digestion-and-measurement design. The digestion module offers dual temperature zones, while the measuring section supports both 360° rotating test-tube colorimetry and cuvette colorimetry. It runs on an Android smart operating system with an 8-inch HD LCD touch screen, fibre-optic detection technology, an imported light source and a built-in large-capacity lithium battery. Two rapid detection principles (spectrophotometry and electrochemistry) are integrated in one instrument. The instrument offers stable performance, accurate measurement, a wide measuring range, powerful functions and simple operation.

II. Applications

The instrument is intended for the determination of multiple water pollutants in domestic sewage, industrial wastewater, groundwater and surface water. It is used for water quality analysis in testing laboratories, municipal authorities, wastewater treatment plants, environmental monitoring stations, universities and research institutes, power plants, centres for disease control, paper making and electroplating plants, aquaculture, biopharmaceutical production, petrochemicals, coal, metallurgy, textiles and the food industry.

III. Detection Items

Spectrophotometric module

COD, ammonia nitrogen.

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 (coloured dissolved organic matter) sensors — several dozen types in total.

IV. Key Features

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

2. Dual colorimetric system supporting both pre-made test tubes and cuvettes.

3. The tube measuring channel uses a 360° precision rotating mechanism, guaranteeing accuracy and improving stability tenfold.

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

5. Portable all-in-one design with a large-capacity lithium battery: digestion and measurement can both be carried out in the field with a single instrument.

6. Built-in thermal printer supporting automatic and batch printing, freely selectable and editable print content, and QR-code printing.

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

8. 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 both coefficient curves and sample curves.

10. Built-in sensor module: four sensors for different parameters can be inserted and measured simultaneously, with direct concentration readout.

11. Sensor measurements can be stored at preset times or manually, and the data can be printed.

12. Built-in instructional videos let users watch the procedure while operating the instrument, making it easier to learn.

13. Measurement, digestion and sensor readings can be performed at the same time, greatly improving efficiency.

14. Detection items can be customised on request.

15. Factory-prepared reagents are supplied: no repeated pipetting or concentrated sulfuric acid preparation is needed — simply add the water sample to the tube.

16. Favourite parameters can be pinned to the top of the item list, avoiding repeated searching.

17. GPS positioning displays the longitude, latitude and landmark of the sampling point in real time; the coordinates are saved with the data and can be uploaded to the cloud platform.
