The Watlow EZ-Zone PID (proportional, integral, derivative) controller commands proportional power to the heating elements
to provide the most accurate and responsive control. The control parameters are matched to the oven size to assure faster
response to setpoint with minimal overshoot. The Watlow EZ-Zone supports custom recipe creation. Each recipe can support
full ramp and soak control for custom applications. A total of 4 recipes with up to 40 steps can be used to configure the oven to
your process.
Integrated Watlow Control Panel
All controls are centrally located on the main panel including power, Watlow EZ-Zone controller with integrated over-temperature limit and recipe control. The gauge panel allows easy access from the front of the unit to the manual vacuum and vent
valves.

DIN 12880 Compliance
SHEL LAB SVAC Series ovens are designed to meet or exceed the performance criteria established through DIN 12880:2007:05 and ASTM
E145-94 (Reapproved 2006.) These criteria set common standards for laboratory oven performance in heat-up, temperature uniformity and
door-open recovery time. Confirmation of temporal and spatial performance is achieved by testing with multi-point temperature probes
strategically positioned throughout the oven chamber interior, including center point positions where stability, equilibrium and setpoint control
are required.
Note: DIN 12880 is an international standard for measuring the performance of electrical laboratory ovens and incubators based on Deutsches Institut Fur
Normung E.V. (German National Standard), 05/01/2007.
