Ventilation type environmental aging test chamber Haida HD-E701

Description

Ventilation type environmental aging test chamber design with sophisticated air-displacement adjustment device and a digital voltage meter, current meter, watt-hours, the timer can be used to measure the air replacement rate. Horizontal circulatory air supply system and both sides of airflow regulator to ensure the internal temperature uniformity and stability.

Corresponding standard：

Accord with ASTM D5423-9（R2005）（Ⅱ-Type oven）and ASTMD 5374-93(2005) UL-1581、GB、VDE、JIS、IEC

Applicable industries：

The aging tank used to test the material heat-resisting for polymer materials (plastics, plastic) and electrical insulation materials, such as: wire and cable sheathing, heat-shrinkable tubing, rubber or PVC materials.

Main parameters:
