in every analysis port, two in all, controlled by a separate
pressure sensor, completely separates from the analysis port,
real-time detecting the nitrogen saturation vapor pressure, and
participating in the theoretical calculation; also the atmospheric
input method to determinate the P0 accurately; Cold trap tube: sample degassing
system has a special cold trap device that can effectively remove
the water, hazardous substances and other impurities, degassed from
the special sample, and it can avoid the contamination of the
vacuum system; Degassing system: Parity, ectopic
vacuum degassing pretreatment systems are controlled by separate
pressure sensors. Two samples can be analyzed simultaneously, also
two samples can be degassed in degassing ports; two independent
sample degassing stations are separate from the sample analysis
ports. The degassing system has two independent heating packages,
two independent temperature control systems, which can be
programmed by temperature control; you can choose another four
external vacuum degassing pretreatment system; Degassing temperature: room
