Convection Temperature DeviceCTD 600

2

Gas Convection heating and cooling

Typical working range: ambient – 600°C

With LN2: -150°C – 600°C

Advantages: - Large temperature range

- Fast heating and cooling

- Enough working space for special accessories like solid torsion bar fixture etc.

Disadvantages: - LN2 needed for below ambient temperatures
