Low Temperature Retraction & Brittle Point Tester
Fully Automated Sub-Zero Testing
High-Efficiency Auto Control
The EKT-100TRB dramatically reduces operator error through its fully automatic and computerized controlling system. It simultaneously holds up to 6 test samples. The critical processes—including specimen elongation and immersion into the -70°C cooling bath—are carried out completely automatically, ensuring precise 1°C/min temperature rising rates.
Real-Time Data & Dual Functionality
Critical data points (time, temperature, and retraction rate) are simultaneously displayed and tracked on the screen during the entire test cycle.
- Automatically calculates TR10, TR30, TR50, and TR70 values.
- Cooling supported by Compressor or Liquid Nitrogen.
- Optional Module: Seamlessly upgradeable to perform Brittle Point testing (ASTM D2137) in the same machine.
Technical Specifications (EKT-100TRB)
