Description
The Impact Specimen Cooling and Heating Temperature Chamber, GenChamber, is a dual-function system for temperature conditioning of Charpy and Izod impact specimens. It is designed to meet the requirements of ISO 148-1 and ASTM E23, and supports both low-temperature soaking and high-temperature stabilization of metallic materials before impact testing.
It suits materials testing laboratories, research and development facilities, and quality control departments that need consistent, repeatable preparation of Charpy and Izod impact specimens.
Both chambers sit in one cabinet, so a specimen batch can be soaked cold or stabilized hot without moving to a second machine.

Two Conditioning Modes
The two chambers work independently and are built for opposite jobs. Which one you use is set by the test temperature your standard calls for.
Low Temperature
Down to -80°C (-112°F)
Compressor refrigeration with thermal equilibrium and circulating stirring.
Cooling is automatic and the stirring mechanism keeps the bath uniform, which is what makes soaking repeatable across a batch. Built-in protections guard against overheating and overcurrent, and an alarm sounds when the target temperature is reached, so a specimen is not left soaking longer than the method allows.
Accuracy≤ ±0.5°C
MediumEthyl alcohol≥ 99.5% purity recommended
High Temperature
Up to 100°C (212°F)
Stainless-steel electric heating with forced air circulation and internal ventilation.
Heat is distributed by a centrifugal fan that keeps air moving continuously, which is how the chamber holds the temperature gradient that the standards require. PID control keeps conditions stable through the heating process, with monitoring resolved to 0.1°C on the display.
