Portable Sewage Multi-parameter Water Quality Analyzer

I. Product Overview

This instrument is an integrated portable water quality analyser based on multi-wavelength spectrophotometry. Digestion, measurement and data transmission are combined in one unit; a built-in multi-wavelength optical system and preset standard curves, together with dedicated pre-prepared reagents, allow dozens of water quality parameters to be determined quickly and accurately at the touch of a button. The design fully meets the requirements of complex on-site water analysis: a large-capacity battery, digestion unit and thermal printer are built in for independent field operation, while 4G/Wi-Fi, GPS and cloud platform functions close the loop from on-site testing to data traceability management.

II. Measuring Principle

The instrument performs quantitative water quality analysis on the principle of spectrophotometry. An LED light source system is used and the optimum analytical wavelength for each parameter is fixed in advance according to the national standard method, ensuring specificity and accuracy. The user applies the supplied pre-prepared reagent; after colour development the test tube or measuring bottle is placed in the measuring compartment, the absorbance at the specific wavelength is measured precisely and the concentration is calculated automatically from the stored standard curve according to the Lambert-Beer law.

III. Applications

Industrial wastewater: influent, process units and outfall monitoring at wastewater treatment stations in electroplating, printing and dyeing, pharmaceutical and food processing plants.
Municipal sewage: influent, biological units, effluent and reuse water inspection at wastewater treatment plants.
Environmental water bodies: rivers, lakes, reservoirs and wetlands, groundwater monitoring wells and private water sources — routine monitoring and pollution screening.
Drinking water safety: drinking water source protection areas, backup sources and rural centralised water supply facilities.
Enforcement and emergency response: surprise sampling at enterprise outfalls, park outfall patrols, on-site screening of sudden water pollution incidents and pollution plume tracking.
Research and teaching: water quality research, process optimisation and on-site testing and data collection for teaching experiments in universities and research institutes.

IV. Key Features

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

2. Turbidity bottle and test-tube measuring channels, switchable with a tube holder.

3. Built-in 6-position digester and 6-position cooling fan with independent control.

4. Measurement, digestion and cooling can be carried out simultaneously, greatly improving efficiency.

5. Detection items can be customised on request.

6. Factory-prepared reagents are supplied: simply add the water sample to the tube.

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

8. 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.

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

10. Built-in instructional videos let users watch the procedure while operating the instrument.

11. Wi-Fi and 4G modules for wireless data upload.

12. Data cloud platform for online storage and short- and long-term trend analysis.

13. 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.
