with alarm, programming and diagnostic
protocols.

in the outer door for easy, eye-level
access.

includes an intuitive pop-up menu,
high resolution LCD for inputs, out-
puts and performance at-a-glance.

graphical display for temperature
verification at-a-glance.
• Precise logic systems control and
adjust to temperature setpoints and
alarm parameters.

inputs are established through pop-
up menus and function keys.

to remote databases, off-site alarm
or data capture systems through
optional communications board
module for compliance monitoring.

the side of the cabinet can be con-
nected to an external alarm system.
