The KR-718 differential scanning calorimeter is high-precision thermal analysis equipment built for capturing heat flow variations of materials during programmed temperature shifts. By measuring heat difference between test specimen and inert reference crucible, the instrument automatically generates DSC curves to detect thermal characteristic parameters including melting point, glass transition temperature, crystallization enthalpy, oxidation induction time and curing peak.

This complete DSC series covers multiple temperature ranges from ultra-low -150℃ up to high 1050℃, equipped with air cooling, semiconductor cooling and liquid nitrogen cooling options. It fully complies with ISO 11357, ASTM E793, ASTM D3895 and other global thermal testing standards, widely deployed in polymer factories, pharmaceutical labs, paint manufacturers, new energy material R&D centers and CNAS certified third-party inspection institutions for material formulation screening and finished product thermal stability certification.

Core Product Advantages

1. High-Stability Thermal Furnace & Imported Heat Flux Sensor
   Adopts newly optimized multi-layer thermal insulation furnace body with even internal temperature distribution, effectively suppressing baseline drift. Imported high-sensitivity E-type thermocouple sensor delivers resolution up to 0.001mW, ensuring excellent curve repeatability even for subtle thermal reactions such as weak glass transition of thin polymer films. Shielded signal circuit eliminates electromagnetic interference from factory workshop environments.

   2.Full-Automatic Multi-Stage Temperature Programming System

   Supports independent setting of heating, constant-temperature holding and cooling segments, with adjustable heating speed from 0.1~100℃/min and maximum isothermal holding time up to 24 hours. The 7-inch 24-bit color touchscreen integrates all parameter settings, real-time curve display and one-click calibration functions, supporting Chinese/English bilingual switching for global operation teams.

   3.Dual-Atmosphere Automatic Gas Switching Module

   Dual independent gas pipelines for nitrogen and oxygen with stepless flow regulation ranging 0~300mL/min. The system automatically switches protective and oxidizing atmospheres during testing without manual pipeline disassembly, ideal for oxidation induction period (OIT) testing of plastic raw materials. Built-in flow real-time monitoring triggers audible alarm when gas supply is abnormal to avoid invalid test data.
   4.Multiple Cooling Configurations For All Test Scenarios

• Air-cooled version: Cost-effective for normal temperature ~600℃ routine plastic testing
• Semiconductor refrigeration model: Covers -40℃ low temperature for low-glass-transition polymer research
• Liquid nitrogen cooling unit: Reaches -150℃ ultra-low temperature for elastomer and cryogenic material analysis

• Bidirectional USB PC Data Interconnection & Powerful Analysis Software

  5.Stable USB data link realizes real-time synchronous curve transmission between host and computer. The matching dedicated analysis software supports simultaneous loading and comparative overlay of multiple test curves, auto-calculates key thermal indicators and exports editable PDF/Excel inspection reports. Standard indium and tin reference samples are supplied for regular temperature calibration to guarantee long-term testing accuracy.

  6.Complete Safety & Easy Maintenance Design

  All high-temperature components are wrapped with thick insulation to prevent operator scalding. Standard aluminum and ceramic crucibles are provided for different sample types, with easy top-opening furnace structure for fast sample replacement. Modular gas flow meter and furnace assembly simplify spare part replacement and daily cleaning to reduce downtime.
