The new chambers also offer improvement in the temperature heat-up time and
pull-down time.

2-4 Improved reliability of the viewing window glass
Glass using heat reflective film suffers deterioration of the film with long-term use,
resulting in impaired visibility. Glass incorporating heating wires can suffer wire breakage
leading to fogging of the glass surface. Utilizing glass reinforced with deposit metal film
has eliminated these defects, providing solidly improved reliability.
2-5 Greatly improved ease of use
Not only responding to the need for visual inspection, we at Espec have responded to the
desire to touch, operate, and measure the specimens by offering optional “reach-in ports”
on the viewing window (one each on the right and left sides, for a total of two ports).
Conventional reach-in ports had screw-on covers, requiring extra time and effort to open
and close. There was also a danger of scratching the glass around the reach-in ports when
opening and closing the screw-on covers, and finding where the covers were put after
they had been removed could cause problems for the operator.
These new chambers have incorporated one-touch swing covers for the reach-in ports.
These covers are easy to open and close, and the operator never has to look for the
covers. (Photo 2)
