ATN-300 Automatic Azotometer kjeldahl nitrogen analyzer

ATN-300 Automatic Azotometer

Our company’s ATN-300 automatic azotometer(protein determinator) is designed in accordance with the Kjeldahl method, mainly for assaying the content of ammonia nitrogen, protein nitrogen in cereals, food, dairy products, beverages, feed, soil, water, medicine, sediment and chemicals. The determination conforms to national standard, AOAC, ISO, etc.

Features:

    1. for solution setting, volume of boric acid solution, the amount of alkali and distillation time can be set up at random

2. 20 groups of experimental procedures can be stored to meet user’s various requirements

3. perfect protection system: remind when digestion tube is not in place, protect steamer furnace from being overheated or over-voltage; alarm when distillation is finished

4. manual and auto, two modes for customer to shift

optional digestion furnace for ATN-300 automatic azotometer

KDN-D series digital-display temperature-controllable digestion furnace have models of 4 holes, 8 holes, 12 holes and 20 holes for user to choose, depending on their detection amount. SO₂ and other poisonous gas escaping from digestion furnace will be discharged by relevant waste gas absorption system, guaranteeing the safety and cleanness of your lab.
