DT-4 Building Materials Combustion Heat Value Tester

Product Information

The combustion heat value tester for building materials and products meets the technical indicators and requirements specified in the national standard GB/T14402-2007 "Combustion Performance of Building Materials and Products - Determination of Combustion Heat Value", and is suitable for determining the combustion heat value of building materials and products. The instrument mainly calculates the combustion heat value of the sample by measuring the increase in water temperature after the sample burns in the oxygen bomb. The operation is simple, the test process is fully automatic, and the data is displayed intuitively

Product Features:

1. Adopting a modular 16 bit AD temperature acquisition circuit ensures temperature measurement accuracy of one ten thousandth bit.

2. The high-precision PT1000 temperature sensor is used, and the temperature measurement module adopts ultra-low temperature drift characteristic electronic components to ensure the stability of the test results.

3. Equipped with a 7-inch true color frog LCD screen, the displayed information is very rich, intuitive, and clear. Implemented simpler and more flexible operations; The direct human-computer interaction method is more convenient to use.

4. It has powerful data processing capabilities and scalability, achieving perfect expression of the instrument. Querying and printing historical data has become simple and easy, providing compatible possibilities for future device networking and data sharing.

5. Real time temperature cooling correction, with relaxed requirements for environmental temperature.

6. The testing process of water injection, drainage, mixing, ignition, temperature collection, calculation, calibration, and printing is fully automated, avoiding human errors on February 15th and greatly improving accuracy and precision.
