Benchtop Features
A nonmetallic thermal break around the door and doorframe stops transfer of heat/
cold to the exterior. (BTZ-133 shown with optional shelf and window.)
Space-saving design
An innovative new layout of system compo-
nents helps make Criterion chambers have
the smallest footprint.
Keeping the refrigeration compressors and
blower fan to the back of the chamber also
reduces noise to the room.
Useful safety features
To protect from the risk of overheating,
there are three levels of protection:
Settable within the programmer 1.
An independent settable monitor 2.
A thermal fuse 3.
In addition, a specimen power terminal
allows the user to safely operate powered
equipment inside or with the chamber. If
the chamber is shut down, the interlocked
device will also be shut down.
Highly reliable operation
The Criterion platform has been re-
engineered from the ground-up to be
consistent, reliable, and easy to maintain.
ESPEC stands behind the chambers with a
comprehensive one-year parts and on-site
labor warranty.
Quality cabinet construction
ESPEC is meticulous about making a
chamber that is more than just functional.
