Vacuum drying oven is specially designed for drying heat
sensitive, easy to decompose and easy to oxidize substances. It can be filled
with inert gas inside the vacuum oven, especially some articles with complex
composition can also be distributed for rapid drying.
Vacuum degree refers to the degree of gas thinning in the
vacuum state, which is usually marked by “high vacuum degree” and “low vacuum
degree “, If the pressure in the measured equipment is lower than the
atmospheric pressure, the pressure measurement requires a vacuum gauge. The
values read from the vacuum gauge are called vacuum. The vacuum value is the
value indicating that the actual pressure of the system is lower than the
atmospheric pressure, that is, the vacuum degree = the atmospheric pressure –
the absolute pressure, the absolute pressure = the atmospheric pressure gauge
pressure (- the vacuum degree).
The international vacuum industry uses “vacuum”, is also
the most scientific use of absolute pressure identification, refers to the
“limit vacuum, absolute vacuum, absolute pressure “, but due to easy
measurement, easy to purchase the measuring instruments ” relative vacuum ” is
also widely used.
More details, welcome for inquiry.
