Charpy Impact Test Specimen Low Temperature Chamber - CHARPY-QualiCHLTC™ 100 Performance Characters
The CHARPY-QualiCHLTC™ 100 is a sophisticated low-temperature chamber engineered for precise and efficient testing of metallic materials at low temperatures, aligning with international standards, including ASTM E23-2018, ISO 148-1:2016, DIN EN 10045-1:1991, JB 5376-1991, and GB/T 229-2007.
Human-Centered Design
The chamber is structured in an ergonomic "L" shape with distinct high and low sections. The high section houses the control unit, making temperature settings, monitoring, and operations accessible and visible. The lower section contains the freezing tank, optimized for straightforward sample placement and clamping. This design also aligns with impact testing machines, facilitating quick, accurate sample positioning.
High-Quality Refrigeration Components
The CHARPY-QualiCHLTC™ 100 uses fully enclosed compressors and an external rotor condensing fan, renowned for their durability, low noise, and use of eco-friendly refrigerants. These components are designed for reliable, long-term performance, meeting high standards for both operational efficiency and environmental responsibility.
Precision Temperature Control
Equipped with a high-precision temperature control system, the chamber incorporates a platinum resistance sensor and stainless steel probe to ensure stability and accuracy in extreme low-temperature conditions. The system includes a low-noise magnetic induction stirring motor, promoting effective agitation and consistent fluidity within the cooling medium, while a durable stainless steel heater maintains uniform temperature distribution.
Versatile Sample Capacity
The CHARPY-QualiCHLTC™ 100 can accommodate up to 60 standard samples (10 x 10 x 55mm) at once, with additional capacity for smaller samples, including sizes 7.5 x 10 x 55mm, 5 x 10 x 55mm, and 2.5 x 10 x 55mm. Universal casters enable easy mobility, and the sample baskets simplify the handling process. A liquid discharge port further facilitates cooling medium recycling and cleaning. Temperature alarms and insulation timing functions support efficient scheduling for operators.
Robust Safety Features
To ensure secure operation, the CHARPY-QualiCHLTC™ 100 integrates a comprehensive protection system, including overload, leakage, grounding, compressor overload, and medium over-temperature (anti-drying) protections, promoting safe, consistent, and reliable performance.
