Advanced Control
Touch-screen controller enhances per-
formance
Imagine walking up to your test chamber and im-
mediately being able to get your test running. The
exclusive SCP-220 programmer makes it a breeze to
set up, run, and monitor your chamber, even for the
infrequent user.
For temperature cycling, the controller allows you to
select step-ramping for the fastest possible transis-
tion, or controlled-ramping to achieve a desired ramp
rate. Guaranteed soak settings allow you to control
when timed soak periods begin.
Remote operation via Ethernet
ESPEC offers the Web Controller, an embedded
server/software solution that allows monitoring and
programming your chamber via any PC on your
network.
No local software to install, just a web browser and
access to the LAN is required. Because there are
only seven screens, all operational functions are
easy to find and use. See our separate brochure or
website for more detail.
Remote control and datalogging is also possible via
RS-232 or IEEE-488 options.
Optional product temperature control
Monitors product temperature •
Enables faster product change rates •
Shortens testing time •
During cycling tests, product temperature can lag
behind air temperatures by 20 degrees or more. Our
optional product temperature control feature lets
you drive faster change rates by directly monitoring
product temperature and overshooting normal air-
temperature setpoints until the product approaches
the desired temperature. By achieving product
temperature faster, soak periods can begin earlier,
saving significant time.
As shown in the example at left, setting the cham-
ber for a 20°C air temperature boost (air at -60°C)
achieved the -40°C product temperature in just 16
minutes, compared for nearly 50 minutes with the
chamber air set at -40°C.
Access to the SCP-220 programmer is on the new console mounted on
the left side of the door.
