Yamato DF & DH Series Fine Ovens deliver high precision temperature control and programmable flexibility for demanding thermal testing applications. With enhanced PID Z control, adjustable airflow, and up to 99-step program sequences, the DF/DH ovens simplify complex temperature profiles with reliable and repeatable performance.
Choose from models with 260°C (DF Series) or 360°C (DH Series) temperature capability, all equipped with powerful safety features, digital control, and high thermal uniformity. Ideal for temperature characterization, thermal cycling, and material stress testing.
Key Features:
- Improved user interface with high-visibility LED display
- High temperature accuracy (±0.1°C for DF, ±0.2°C for DH)
- Adjustable air speed and rapid exhaust damper
- Programmable: 99 steps, 99 patterns, with repeat operation
- Displays for power consumption, CO₂ emissions, and heater output
- Cable port and rear exhaust for easy data collection and quick cooldown
