KRW-300D Vicat Softening Point Tester
Product Introduction
The KRW-300D Vicat Softening Point Tester is a professional heat deflection temperature (HDT) and Vicat softening point testing instrument designed for evaluating the thermal deformation characteristics of polymer materials.
Based on the latest international and national testing standards, the KRW-300D is widely used to measure the Vicat softening temperature and heat deflection temperature of plastics, polymers, and other thermoplastic materials.
The instrument adopts digital LCD display technology and digital dial gauge displacement measurement, providing accurate temperature control, reliable operation, and precise deformation measurement. With optional multi-station testing configurations, the KRW-300D is suitable for laboratory research, material development, and industrial quality control.

Performance Features
•   Dual-function thermal testing system
Measures both Vicat softening temperature and heat deflection temperature of polymer materials.
•   High-precision temperature control
Provides accurate heating control with maximum temperature error within ±0.5℃.
•   Digital displacement measurement
Uses a digital dial gauge for precise deformation monitoring.
•   Wide temperature range
Supports testing from room temperature up to 300℃.
•   Multiple test station options
Available with 2, 3, 4, or 6 testing stations according to user requirements.
•   Automatic heating protection
Upper temperature limit setting allows automatic heating stop when the preset temperature is reached.
•   Stable thermal structure
Low thermal expansion sample rack improves measurement accuracy.
•   Reliable cooling system
Supports natural cooling and water cooling according to temperature conditions.

Working Principle
The KRW-300D Vicat Softening Point Tester evaluates polymer thermal performance by measuring deformation behavior under specified temperature and load conditions.
Vicat Softening Point Test:
1. A standardized needle applies a specified load onto the polymer sample.
2. The sample temperature is gradually increased at a controlled heating rate.
3. When the needle penetrates to the specified depth, the corresponding temperature is recorded as the Vicat softening temperature.
Heat Deflection Temperature Test:
1. A test specimen is placed on a support frame.
2. A defined bending load is applied.
3. The temperature is increased at a controlled rate.
4. The temperature at which the specified deformation occurs is recorded as the heat deflection temperature.
The KRW-300D uses digital temperature monitoring and displacement measurement systems to provide accurate and repeatable thermal deformation test results.
