LBT-JM800J Precision Hot-Air Circulation High-Temperature Oven

Name: LBT-JM800J Precision Hot-Air Circulation High-Temperature Oven
Brand: Laibote (Tianjin) Testing Machinery
Availability: InStock

This product employs recirculating air for constant‑temperature drying, featuring a high degree of智能化 and requiring no dedicated operator. The temperature is intelligently self‑regulated by the user and can reach the desired level in the shortest possible time. Operating temperatures range from ambient up to a maximum, with users free to select any value within this range; once set, the built‑in automatic control system maintains a stable temperature. An electric blower ensures forced convection of hot air throughout the chamber, resulting in more uniform internal temperatures. It is widely used for precision baking, drying, tempering, preheating, shaping, and processing of materials such as electronics, electrical machinery, telecommunications equipment, electroplating products, plastics, metal and chemical components, foodstuffs, printed circuit boards, powders, impregnated coatings, glass, ceramics, wood products, and building materials.

LBT-JM800J Precision Hot-Air Circulation High-Temperature Oven

Description

Product Introduction:

This product employs recirculating air for constant‑temperature drying, featuring a high degree of智能化 and requiring no dedicated operator. The temperature is intelligently self‑regulated by the user and achieves optimal drying performance in the shortest possible time. Operating temperatures can be set anywhere from room temperature up to the maximum limit, with the internal automatic control system maintaining a stable temperature once selected. Equipped with an electric blower, it promotes forced convection of hot air within the chamber, ensuring more uniform temperature distribution. It is widely used for precision baking, drying, tempering, preheating, shaping, and processing of materials such as electronics, electrical machinery, telecommunications equipment, electroplating products, plastics, metal and chemical goods, food items, printed materials, pharmaceuticals, PCBs, powders, impregnated or coated substrates, glass, ceramics, wood products, and building materials.

Product Features:

Locking-type elastic adjustment door lock, ensuring excellent vacuum integrity.

The enclosure is constructed from high-quality cold-rolled steel sheet, with an electrostatic powder-coated finish that delivers a hard, durable coating and excellent rust resistance.

The studio is constructed from high-quality galvanized steel, featuring rounded corners, a smooth and streamlined design, and easy-to-clean surfaces.

Between the cabinet body and the working chamber, ultra-fine glass wool insulation is filled, providing excellent thermal insulation and effectively ensuring stable, accurate internal temperatures while minimizing environmental influences.
