AD-2AZ Portable Ammonia Nitrogen Tester Price

1、 Product Overview
The AD-2AZ ammonia nitrogen tester is suitable for detecting ammonia nitrogen concentration in large, medium, and small water plants, industrial and mining enterprises, domestic or industrial water, in order to control the ammonia nitrogen in water to meet the specified water quality standards.

2、 Principle:

This instrument applies the principle of microcomputer photoelectron colorimetric detection to replace the traditional visual colorimetric method. Eliminating human error, the measurement resolution is greatly improved. When measuring, when the tested water sample is poured into the reagent, the water sample will turn yellow. Then place this water sample into a photoelectric colorimetric stand, and the instrument will compare the depth of yellow to determine the concentration of ammonia nitrogen.

Technical Specifications:

3、 Characteristics:

1. Microcomputer, touch sensitive keyboard, clear LCD digital display, easy to use.
2. It can be automatically zeroed and calibrated at 5 points.
3. High performance lithium battery, can be used continuously for 4 hours after charging for 4 hours, ready to use.
＊4. Adopting high-precision circuit system, low drift, the instrument can work stably for a long time, and the water sample can be read by placing ammonia nitrogen reagent.

＊5. This instrument uses a specially designed high-intensity long-life light source, a constant light source semiconductor emitter (Zhuna Li No. 99226785.2), with a stable light source and a lifespan of up to 20 years. It can be used directly without preheating when turned on.
6. The instrument resolution is as high as 0.01mg/L.

＊7. Dual use of AC and DC, easy to carry. In addition to being used in laboratories and fixed places, it can also be directly used for on-site water sample measurement and field use.
