Impact Specimen Cooling and Heating Temperature Chamber – GenChamber
Metal Testing Equipment
Standards
ISO 148, ASTM E23, ASTM E74 (Class AA)
Description
The Impact Specimen Cooling and Heating Temperature Chamber – GenChamber is a high-performance dual-function system engineered for precise temperature conditioning of Charpy and Izod impact specimens. Designed to meet the requirements of ISO 148-1 and ASTM E23, this chamber supports both low-temperature soaking and high-temperature stabilization for metallic materials prior to impact testing.
The low-temperature mode uses an advanced compressor-based refrigeration system combined with thermal equilibrium and circulating stirring mechanisms, delivering automatic cooling and uniform temperature control down to -80°C. This ensures consistent preparation of impact notch specimens and supports repeatable, reliable test results. Built-in safety protections guard against overheating and overcurrent conditions. Additionally, an integrated alarm notifies the user when the target temperature is reached, guaranteeing precise timing for specimen preparation.
The high-temperature function features a durable stainless-steel electric heating system with forced air circulation and internal ventilation for uniform heat distribution. The system is equipped with PID temperature control and offers high-resolution monitoring with a 0.1°C display accuracy, maintaining stable conditions throughout the heating process. A centrifugal fan ensures continuous airflow and temperature uniformity, meeting industry-standard temperature gradient requirements.
This temperature conditioning chamber is ideally suited for materials testing laboratories, research and development facilities, and quality control departments that require consistent and reliable preparation of Charpy and Izod impact test specimens.
