Control modes & configurations

• Linear mode — full linear control, adjustable 3–20 °C/min; constant slope for repeatable qualification tests.
• Nonlinear mode — adjustable 3–30 °C/min with faster peak ramps for accelerated stress screening; humidity function combinable.

Features

• High-speed linear ramp capability to reduce cycle time while maintaining profile repeatability.
• Temperature and optional humidity coverage with extended ranges via dehumidifier.
• PID + SSR BTHC control for stable regulation during high-speed ramps.
• Multiple internal volumes and configurable option levels (A~F).

Built-in / key functions
