1. Fully transparent integrated heat-resistant spray-proof cover, which can directly observe the state of water sample and ensure safe and reliable digestion; 2. The upper end of the digestion module is equipped with aeronautical insulation layer to effectively prevent burns; 3. Large-screen LCD Chinese display, User-friendly menu design, the operator can quickly master the instrument operation method;
1. Karl-Fischer capacity method ammonia nitrogen analyzer, the structure is relatively simple, the volume and precision are moderate, suitable for the determination of moisture content 10PPm~10%, generally used in chemical, pharmaceutical and packaging industries with strict requirements on water. The price ranges from a few thousand to several tens of thousands.
Total phosphorus determination and total nitrogen determination were developed according to the published documents, and the measurement results were accurate and effective. COD adopts closed digestion colorimetry, total phosphorus adopts closed digestion colorimetry, and total nitrogen adopts closed digestion ultraviolet photometric absorption method. The instrument is widely used in environmental testing, sewage treatment, scientific research units and universities.
The heavy metal analyzer is a colorimetric analysis method based on the reaction of a sample to be reacted with a developer to form a colored compound that selectively absorbs electromagnetic radiation. The instrument is composed of a silicon light source, a lens, a colorimetric bottle, a photocell, and a signal microprocessor, and can directly display the content of ammonia nitrogen in the sample to be tested on the liquid crystal screen. The ammonia nitrogen detector is suitable for the detection of ammonia nitrogen concentration in large, medium and small water plants and industrial and mining enterprises, domestic or industrial water, in order to control the ammonia nitrogen of water to meet the specified water quality standards.
