Introduction

The instrument can quickly measure COD, ammonia nitrogen, Total phosphorus, Total nitrogen, heavy metals (total chromium, hexavalent chromium, copper, zinc, nickel, iron) in various water qualities, and integrates mature technologies in the field of water quality analysis to make the entire analysis system It is more perfect, the operation is simpler and faster, and the detection results are more 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. Tongao Technology TR 6900DZ Desktop Water Quality Detector Details Figure 1

● 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)

- Total Nitrogen ( TN )

- heavy metal

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

- Phosphate - Manganese method COD

- Nitrite - Nitrate Nitrogen

- Free/Total Chlorine - Fluoride

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.

FAQ

QIs the price listed on the website the final cost for overseas purchases?

ANo, it isn't. This is the ex-factory price of the product in the Chinese Mainland. In addition to this price, buyers from different countries need to account for additional costs such as shipping fees, tariffs, and others.
