Description
Uses:
WHL-25 is an improved drying oven, which applies to labs of industrial enterprise, scientific research institution and health and medicine unit for drying, baking, heating and other experimental use.
Characteristics:
1. High-quality cold rolling steel electrostatic spraying exterior.
2. Stainless steel or cold rolling steel inner chamber treated by anti-corrosion technology; Foursquare semicircle transition, convenient to clean; Space between shelves is adjustable.
3. Optional pointer meter or intelligent temperature controller; Intelligent controller with PID program, dual digital display, light-touching operational key, and with function of timing and over-temperature protection.
4. Door with wide double-layer tempered glass observation window, adjustable air-tight buckle lock, and silicon rubber seal, which provide good seal ability and efficiently prevent heat loss.
Note:
A means: Intelligent Controller and steel Inner Chamber
AB means: Intelligent Controller & Stainless Steel Inner Chamber
Characteristics:
1. In the work room, the hot air is convective naturally and cyclically.
2. Digital display microcomputer intelligent PID temperature controller.
3. New anti-hot handle.
