Brief description of principle:<\/span><\/strong><\/p>\n

 <\/span><\/p>\n

In an acidic solution, trivalent chromium is oxidized by potassium permanganate to hexavalent chromium, and hexavalent chromium reacts with diphenylcarbazide to form a purple-red complex, which is measured at a wavelength of 540nm.<\/span><\/p>\n

 <\/span><\/p>\n

Characteristic:<\/span><\/strong><\/p>\n

 <\/span><\/p>\n

1. The main components adopt imported brands to ensure their accuracy, stability and reliability;<\/span><\/p>\n

 <\/span><\/p>\n

2. Infrared measurement unit, accurate quantification;<\/span><\/p>\n

 <\/span><\/p>\n

3. Adopting positive\/negative pressure current technology, the peristaltic pump tube does not pass through liquid, which is stable and durable.<\/span><\/p>\n

 <\/span><\/p>\n

4. Three-point automatic calibration, high linear correlation;<\/span><\/p>\n

 <\/span><\/p>\n

5. Special LED light source, high signal-to-noise ratio;<\/span><\/p>\n

 <\/span><\/p>\n

6. RS232\/RS485 interface, standard MODBUS protocol, can remotely read the operating status and related data of the instrument;<\/span><\/p>\n
