Features:

The first cooling-water-free condensation technology of the world:

based on the second generation DDP cooling-water-free condensation technology, the Azotometer can effectively condense without using cooling water, never worry about the high temperature or low press of cooling water.

The revolutionary technology has three advantages.

Firstly, it condenses at 1℃, the water vapor and ammonia is liquefied Immediately, and the ammonia can be absorbed without loss，So the result is reliable, accurate and reproducible.
Secondly, it can save a lot of water in the experiments, in line with the current trend of water saving. While traditional Azotometer using fluid water to cool down, consuming about 10L of water per minute, if it works 8 hours a day, 1200 tons of water will be wasted every year.
Thirdly, it is unnecessary to configure faucet or cycle chiller Individually, so that it can be placed anywhere in the lab.

The experimental data can be reproduced accurately: firstly, the steam monitoring technology ensures that the effective distillation time and the setting distillation time can be consistent completely. Secondly, the stability of the steam is controlled precisely by microcomputer. Thirdly, comparing with normal Azotometers which use pneumatic pipetting technique, our devices add a regulator system innovatively to guarantee the consistency of each dosing, so the data is more accurate.

Intelligent automation: using a colorful touch-screen make the operation easy and convenient. In addition, the process of adding boric acid, adding alkali, distilling and rinsing is all automatic.

The material of the Azotometer is of great quality and anti-corrosion: We use CE certification pressure pumps, valves and Saint-Gobain brands imported pipes.

Applied flexibly: the distillation power is adjustable; the Instrument is suitable for experimental research.
