DWS-296 type ammonia (nitrogen) analyzerDetailed product description：

DWS-296 ammonia (nitrogen) analyzer

As one of the main nutrients for plants and microorganisms, the determination of ammonia nitrogen is a major content of biochemical monitoring, which helps to promote agricultural development and guide environmental protection and management. This instrument uses an ammonia sensitive electrode for rapid determination of ammonia (nitrogen) in water samples. The method is simple, labor-intensive, accurate, and has strong anti-interference ability. Samples have colors, metal ions, and turbidity that do not affect measurement, and can be widely used for the determination of ammonia nitrogen in various industries such as environmental protection.

Main functions and features of DWS-296 ammonia (nitrogen) analyzer:

1. The instrument adopts a dot matrix LCD display and a Chinese operation interface, making it easy and convenient to use. Adopting innovative touch keys, with good reliability
2. The measuring device adopts a constant temperature system, which has good measurement reliability and stability
3. Three displays: mV, mg/L, pN
4. Manually input two-point calibration at any time
5. Three reading methods: key reading, timed reading, and reading when 1mV does not change per minute
6. The measurement results can be stored, deleted, viewed, and printed. Up to 200 data can be stored
7. The instrument is equipped with an RS-232 interface, which can be connected to a TP-16 printer to print measurement results or communicate with a computer
8. The instrument has a power-off protection function. After the instrument is used and turned off or in the event of abnormal power failure, the measurement data and set parameters stored inside the instrument will not be lost, and the operation is simple
