Kjeldahl Nitrogen Analyzer Kjeldahl Digestion Apparatus

ATN- 3 00 A uto matic A zotometer

O ur company’ s ATN-300 automatic azotometer(protein determinator) is designed in accordance with the Kjeldahl method , mainly for assay ing the content of ammonia nitrogen, protein nitrogen in cereals, food, dairy products, beverage s, feed, soil, water, medicine, sediment and chemicals. The dete rmination 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 requirement s

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
