1、 Working principle:

DS-NH100C Ammonia Nitrogen AnalyzerUsing Nessler's reagent to react with ammonia nitrogen in the form of free ammonia or ammonium ions, a yellow brown complex is formed. The color of the complex is proportional to the ammonia nitrogen content. The ammonia nitrogen content is calculated using an optical colorimetric method and a single-chip computer.

DS-NH100C Ammonia Nitrogen AnalyzerWidely used for measuring water quality of surface water, industrial wastewater, domestic sewage, etc.

2、 Technical parameters:

1. Measurement range: 0.02-25mg/L (divided into two ranges: 0-5mg/L and 5-25mg/L). Excess range can be measured after dilution

2. Basic error: ± 3% (F.S)

3. Repeatability: ≤ 2%

4. Dimensions: 266mm × 200mm × 130mm

5. Power supply: 220V

3、 Product features:

1. Using imported high-performance, long-life, and high brightness light sources, coupled with a highly stable optical system, to achieve higher repeatability and accuracy of the instrument.

2. Use high-performance, low-power microcontrollers and large screen LCDs with Chinese character menus for easy operation and intuitive display.

3. It can store 10 working curves and 199 historical records without losing them during power outages.

4. The host chassis is made of molded ABS material, which has good corrosion resistance.

4、 Preparation checklist:

1 host, 1 set of reagents, 10 colorimetric tubes, 1 power cord, 1 test tube rack, 1 user manual, 1 product certificate, and 1 warranty card.
