I. Product Overview

The handheld multi-parameter water quality analyser is developed with reference to HJ/T 399-2007, HJ 535-2009, HJ 671-2013 and HJ 636-2012. It rapidly determines COD, ammonia nitrogen, total phosphorus, total nitrogen and dozens of other concentration parameters in water. The instrument has a high-definition colour LCD touch screen, an Android smart operating system, a Chinese interface and a Chinese/English keyboard for user-friendly operation. Paired with a 6-position smart digester it enables rapid field testing.

II. Applications

Widely used in emergency monitoring, industrial wastewater, domestic sewage, wastewater treatment, pharmaceutical and chemical production, food and beverages, textile printing and dyeing, electroplating, paper making, petroleum and metallurgy, river remediation, research institutes and universities.

III. Key Features

1. Android smart operating system for simpler, faster operation.

2. Cloud monitoring platform: results are transmitted wirelessly to the platform for short- and long-term water quality analysis and assisted management.

3. Built-in operating procedures: simple operation, no training required.

4. Fast detection with on-site data readout.

5. Compact and lightweight for convenient field testing.

6. Small, elegant housing with stable, maintenance-free operation and excellent cost performance.

7. Imported cold light source with stable optical performance and a service life of up to 100,000 hours.

8. AC/DC operation with a built-in rechargeable lithium battery — durable and suitable for continuous indoor and outdoor work.

IV. Detection Items

Routine water quality parameters: COD, ammonia nitrogen, total nitrogen, total phosphorus, phosphate, nitrate, nitrite, permanganate index, turbidity, colour, suspended solids, dissolved oxygen and pH.

Disinfection parameters: free chlorine, total chlorine, chlorine dioxide, available chlorine and chlorite.

Heavy metals: iron, total iron, copper, total copper, aluminium, zinc, manganese, total manganese, nickel, total nickel, hexavalent chromium, total chromium, mercury, total mercury and arsenic.
