Temperature uniformity is typically verified by performing a simple multi-point temperature survey at the same time the chamber is controlling at your target setpoint. In practice, you place independent reference temperature probes at representative locations within the working volume, allow the system to stabilize, then confirm the readings are consistent across positions while the controller is holding the set temperature.

A common verification approach in a Charpy workflow includes:

• Set the chamber to the required conditioning temperature and let it reach steady state.
• Position multiple reference probes (or instrumented dummy specimens) at the center and near the outer boundaries of the load area.
• Record readings over a defined soak period to confirm both spatial uniformity and short-term stability.

Results can vary with loading pattern, specimen mass, bath medium and level, circulation conditions, and the selected cooling approach (compressor-based vs liquid nitrogen models).
