Constant-temperature Drying Oven
Product Characteristics
Product characteristic:
1. In the workroom, the hot air is convective naturally and cyclically.
2. PID micro-computer intelligent temperature controller with functions of over-temperature protection.
3. Standard highlight LED instrument running light.
4. New anti-hot handle.
WHLL-BE series have the following characteristics other than the above functions.
1. LCD temperature controller. SSR to make sure the safety
2. Over-temperature protection system
3.High precision digital independent temperature limiter
