The WHL-30B Constant-Temperature Drying Oven is a compact laboratory oven designed for drying, baking, and heat treatment applications requiring stable and uniform temperature control. It operates using natural convection, allowing hot air to circulate naturally and evenly inside the chamber.
Equipped with a PID micro-computer intelligent temperature controller, the WHL-30B ensures precise temperature regulation with built-in over-temperature protection for safe operation. The high-brightness LED display provides clear visibility of operating status, while the anti-hot handle enhances user safety during high-temperature use.
The oven features a mirror-finished stainless steel inner chamber for durability and easy cleaning, along with a cold-rolled steel exterior coated with electrostatic spraying for long-term reliability. With a 30-liter capacity and a temperature range of RT+10°C to 300°C, it is ideal for laboratories, educational institutes, and quality control environments.
