Hot-Air Circulation Drying Oven
Plastic-Raw-Material Drying

The QM230 forced-convection drying oven uses a digital PID controller and hot-air forced convection to deliver uniform, stable chamber temperature for product drying and plastic-raw-material moisture removal. Common range +5~250 °C, temperature accuracy ±1 °C at 100 °C, with optional 350 °C high-temp type and horizontal-flow convection; a stainless interior and height-adjustable shelves suit different specimens.

From plastic pellets to electronic components - material drying is a key step before processing and testing; excess moisture causes molding defects or test errors. Hot-air circulation ensures even chamber temperature and precise PID control, making it a foundational lab drying/dehumidifying device.

Designed for drying/dehumidifying evaluation - hot-air circulation plus PID control for plastic/electronic raw materials.
