Fully-automatic Kjeldahl Analyzer LKA-C10 conducts titration and distillation simultaneously so as to neutralize the ammonia gas released which enhance the test efficiency and avoid the overflow of ammonia. It stand with a measuring range from 0.1 to 200 mgN which gives a maximum recovery of ≥ 99.5 %. The operating ambient temperature of the device starts from 10 °C to 35 °C. 8.0-inch LCD touch screen is used to set the distillation time, the amount of diluent, acid liquor and alkali. Diaphragm pump is used to add reagent so that the injure caused by high pressure pump can be neglected. Wireless network modules is installed for realizing remote data transmission to test data processing and report printing.
