Shel Labto GRAVITY CONVECTION OVENS SGO1, Amb 20 to 306℃
This unit has triple wall construction and easy to read microprocessor
controls. Adjust the air exhaust from the chamber without putting your fingers
near the heat source. Even at temperatures of 306℃, the outer skin of this unit
meets all CE requirements, meaning your application will stay hot but your
work-space will not.<br>This gravity convection oven provides a degree of
uniformity comparable to most forced air ovens on the market. The 99 min 59 hr
digital timer has an independent control so its use is optional. Once the timer
expires the power is cut to only the heating elements.
High Temperature Performance
SGO Series ovens are available in 110-120v, 220-240V, 50/60Hz configurations and achieve temperatures up to 306℃ with fast ramp-up and recovery times.
Heat-Up Rapid heat-up times to 306℃ depend on voltage selected. Published heat-up performance is based on a standard cabinet under controlled testing at a 20℃ ambient temperature, line voltage±10% of specified voltage.
Recovery Upper vents are closed when recovery times following door openings are tested. Published recovery performance is based on a standard cabinet under controlled testing at a (22± 3)℃ ambient temperature, line voltage±10% of specified voltage.
Control, Timer Program, and Monitoring
The advanced loop PID (proportional, integral, derivative) controller commands proportional power to the heating element to provide the most accurate and responsive control. Each controller is matched to the oven size to assure faster response to setpoint without overshoot, and quicker recovery following door openings. The on-board timer permits programmed dwell cycles with automatic shut-off for custom applications. Indicator lights are included for visual status feedback on critical functions.
Integrated Control Panel
All controls are centrally located on the main panel including manual power and timer on/off switches, independent overtemperature control, digital temperature and timer setpoint adjustments, and indicator lights for all functions.
DIN 12880 Compliance
SHEL LAB SGO 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.
