The NGT Series Low Temperature Chamber is designed to condition Charpy impact specimens at controlled sub-zero temperatures prior to testing. It cools specimens uniformly and maintains a stable setpoint to support consistent, repeatable results.
Available conditioning targets include -30°C, -60°C, -80°C, -100°C, and -196°C, depending on the selected model.
The system is engineered around thermal balance and circulation to help minimize temperature gradients between specimens and across the chamber volume. A high-precision self-adjusting controller and platiniridium sensor provide accurate monitoring and straightforward operation.
For cooling performance across the full range, the series uses two proven approaches. NGT-60 and NGT-80 rely on compressor-based refrigeration for stable low-temperature conditioning. For extended ultra-low capability, NGT-100 and NGT-196 use liquid nitrogen cooling to reach and maintain the lowest temperature setpoints.
The NGT Series is used in materials testing labs and quality control environments that perform low-temperature Charpy impact testing, where specimens must be conditioned to a defined temperature before being transferred to the pendulum impact tester.
It is commonly applied to metallic materials and alloys evaluated for toughness and brittle-to-ductile transition behavior, including carbon and stainless steels, aluminum alloys, and nickel-based alloys, as well as weld procedure qualification and production lot verification programs.
