TONGAO TR 6900D COD Ammonia Nitrogen Total Phosphorus Total Nitrogen Turbidity Suspension STIP-scan

Introduction

The instrument can quickly measure COD, ammonia nitrogen, Total phosphorus, Total nitrogen, turbidity, suspended solids, etc. Stable and reliable. Widely used in emergency monitoring, industrial wastewater, domestic (CN) sewage, sewage treatment, pharmaceutical and chemical industry, food, beverage, textile printing and dyeing, electroplating, papermaking, petroleum metallurgy, river management, scientific research units, colleges and universities and other fields.

operating principle

The integrated digestion colorimetric tube and the multi-channel water quality rapid analyzer can be used seamlessly, and are compatible with φ25mm colorimetric tubes.

● The detection of each parameter conforms to national standards, industry standards or international standards.

●  Built-in two COD detection methods

Method 1: HJ/T399-2007 (national standard)

Method 2: Import detection method

●  The standard detection parameters are as follows:

- COD (premade reagents)

- COD (powder pack reagent or custom reagent)

- Ammonia nitrogen (NH3-N)

- Total phosphorus (TP)   

- Turbidity - Suspended Solids (SS)

●  Strong scalability in the later stage, including but not limited to the following parameters:

- Total Nitrogen - Phosphate

- Total chromium - Hexavalent chromium

- Iron - Nickel

- zinc - copper

 …

Principle

1. Digestion colorimetric integrated tube

The digestion and colorimetric integrated tube is used for operation, and the digestion of the sample and the reading of the result share a reaction tube, and there is no need to transfer the liquid to the cuvette for detection.

2. Display the result directly

A cold light source with a specific wavelength is used to measure the absorbance of the sample, and the instrument system converts the detection result directly into the sample concentration value through a specific algorithm. 

3. Measure multiple times and remove outliers

Measure the water sample 10 times or more, and take the average value after removing outliers, so as to reduce the influence of dirt, scratches, fingerprints or defective glass tubes on the results.

4. Detection of abnormal prompts

Prompts for abnormal detection, such as prompts for blank comparison, prompts for results exceeding the upper limit of the range, etc.
