Automatic kieldahl apparatusNo need for circulating cooling water machine

Based on DDP (Dual Dragon Pole) second-generation water free condenser technology, the instrument does not require tap water cooling and can effectively condense at high water temperatures and zero water pressure.

Without the need for specialized faucets and chillers, it can be freely placed in the laboratory, saving valuable laboratory space.

Laboratories with large sample sizes save 1200 tons of water per instrument per year.

Advantages of fully automatic nitrogen analyzer

Steam temperature monitoring ensures that the distillation time of each sample is truly consistent.

Adopting steam stabilization technology to achieve high repeatability in measurement.

Constant pressure flow path system: Constant pressure liquid addition ensures more accurate and stable sample addition accuracy.

Low temperature condensation at 1 ℃, instant liquefaction and absorption of water vapor and ammonia without loss.

Automatic performance of fully automatic Kjeldahl nitrogen analyzer

■ True color touch screen operation, process display, simple and fast.

Automatic acid addition, automatic alkali addition, automatic distillation, and automatic rinsing.

The distillation power can be adjusted, which is a practical function for research laboratories.
