Forced Convection Oven (FCO)
The FCO is the premier temperature device for mechanical
analysis of solids, featuring the fastest temperature response,
extreme oxygen exclusion and unrivaled thermal uniformity.
This gas-convection oven is designed for optimum temperature
stability, extremely rapid heating and cooling, and ease-of-use
over the temperature range of -150°C to 600°C. This powerful
heating mechanism can heat at controlled rates up to
60 °C/min. An available liquid nitrogen cooling system is
employed to achieve rapid, uniform and efficient cooling to
temperatures as low as -150
•
C. Altematively, mechanical chiller
systems can also be used to cool as low as -1 00
•
C without the
need for liquid nitrogen.The FCO provides exceptional exclusion
of oxygen, making it an effective option for high temperature
testing of polymers with poor oxidative stability. Superior
temperature stability and uniformity is achieved through the use
of twin element heaters, which produce counter-rotating airflow
in the oven chamber to heat the sample quickly and without
thermal gradients.
The FCO can be mounted on either side of the test station and
comes standard with a long-life intemal LED lamp and window
viewing port. An optional camera viewer can be used to record
real-time sample images throughout experiments. This visual
record is helpful for data validation and sample condition
verification.

RSA-G2 I SOLIDS ANALYZER
The Forced Convection Oven is designed
to
optimize temperature response time,
uniformity and stability .
Gas is passed
over two resistive gun heaters and into
the specially-shaped oven cavity which
optimizes gas mixing and uniformity. Up to
five thermocouples within the oven make
continuous measurements of temperature
and are used to determine what power and
gas flow should be commanded to each
heating gun to maintain the ideal thermal
environment.
The FCO can be fitted with an optional camera viewer accessory. The camera includes additional lighting
and focus controls which can be adjusted through the TRIOS control software. During the experiment real-time
images are displayed in the software and images can be stored with data points for subsequent viewing.
