Constant-temperature Drying Oven
Used for drying, baking, heat treatment
Characteristics:
- In the workroom, the hot air is convective naturally and cyclically.
- PID micro-computer intelligent temperature controller with functions of over-temperature protection.
- Standard highlight LED instrument running light.
- New anti-hot handle.
WHLL-BE series have the following characteristics other than the above functions.
- LCD temperature controller. SSR to make sure the safety.
- Over-temperature protection system.
- Independent temperature limiter.
