ASTM D4419 Low Temperature Differential Scanning Calorimeter

KN-4419 Low Temperature Differential Scanning Calorimeter

Overview

    KN-4419 Low Temperature Differential Scanning Calorimeter conforms to ASTM D4419 Standard Test Method for Measurement of Transition Temperatures of Petroleum Waxes by Differential Scanning Calorimetry (DSC). DSC in a convenient and rapid method for determining the temperature limits within which a wax undergoes during transitions. The highest temperature transition is a solid-liquid transition associated with complete melting; it can guide the choice of wax storage and application temperatures. The solid-solid temperature transition is related to the properties of the solid, that is, hardness and blocking temperature.

Instrument purpose
       Measure the physical and chemical changes related to heat, such as glass transition temperature, melting point, melting temperature, crystallization and crystallization heat, phase transition reaction heat, thermal stability of products, curing / cross linking, oxidation induction period, etc.  

Features

1. The new fully enclosed metal furnace design structure greatly improves the resolution and resolution as well as better baseline stability. 

2. Adopt professional alloy sensor, more corrosion resistance, oxidation resistance, high sensor sensitivity.

3. Perfect two-way atmosphere control system, precise control of purge gas flow, automatic switching of software settings, data directly recorded in the database.

4. With Cortex-M3 core arm controller, the operation speed is faster and the temperature control is more accurate.

5. USB two-way communication is adopted, which is more convenient to operate and supports the function of self recovery connection.

6. The 7-inch 24 bit color full-color LCD touch screen is used to display the status and data of the instrument in real time.

7. The instrument is equipped with standard materials, and users can calibrate each temperature section by themselves, so as to reduce the error of the instrument.

8. Intelligent software design, automatic drawing of the whole process of the instrument, software can realize various data processing, such as calculation of enthalpy, glass transition temperature, oxidation induction period, melting point and crystallization of substances, etc.
