Drying Oven — Natural Convection
Application Overview
Using natural convection as hot air rises, this oven provides quiet operation, low dust and slow airflow. It is suitable for drying, baking, wax melting and sterilization.
Product Features
- The stainless-steel chamber has rounded corners for easy cleaning;
- Natural-convection circulation is quiet and prevents sample evaporation during experiments;
- A digital microcomputer P.I.D temperature controller with overtemperature-deviation protection and a timer provides precise, reliable temperature control;
- An independent temperature-limit alarm system automatically interrupts operation if the limit is exceeded, ensuring safe experiments without accidents (optional);
- An optional printer or RS485 interface connects a printer or computer to record changes in temperature parameters;
Multi-segment Programmable Controller (Optional)
- The multi-segment LCD programmable controller displays multiple parameters on one screen. Its menu-based interface simplifies complex tests and provides automatic control and operation;
- Multi-segment temperature, time and heating-rate parameters can be set and programmed together. Functions include controlled temperature ramps and gradual heating from the initial chamber temperature. Automatic start, standby and shutdown can also be preset;
- 7 programs with 63 programmable steps can be preset, with 9 steps per program and a time setting of 0~5999 minutes per program;
