1. The instrument adopts the built-in fixed oscillator with anti-ULTRAVIOLET design, which is compact and compact in appearance. It can be cleaned automatically to ensure the safe use of the glass adsorption column.
2, the use of precision control valve to adjust the pressure, precision pressure gauge display, easy to operate and observe.
3. Equipped with noiseless air pump, the operator can easily use it in a quiet environment.
4. The instrument adopts four-column design and imported precise adsorption column, which can be used for comparison sample at the same time.
