Excellent Quality Building Material Combustion Calorific Value Tester
Introduction to building material combustion calorific value tester:
BXT-JL building material combustion calorific value tester, also known as building material product combustion calorific value tester, building material combustion calorific value calorimeter, is to place a specific quality building material pattern in the test environment under standard conditions to test the type of combustion heat value. Under standard conditions, the test is based on the test temperature and the heating value of the model is calculated taking into account all heat losses and latent heat of vaporization.

Microcomputer automatic control
Compact structure, beautiful appearance, easy installation and maintenance, and low failure rate.
It is small in size and is manufactured in a large number of molds with high precision.
The repeatability and reproducibility of the heat test of building materials is better than the requirements of GB/T14402-2007.
High degree of automation, automatic use of the amount of water in the built-in container
Optional refrigeration system: adopts compressor cooling mode, automatically adjusts the temperature of the inner and outer cylinders, reduces the cooling correction coefficient, and makes the measurement results more accurate. The temperature of the experimental process is raised to zero by using a unique refrigeration temperature control system. The stability and accuracy of the experimental results are guaranteed. The unique semiconductor refrigeration water circulation system can determine the cooling capacity according to the previous heat generation, balance the circulating water system, keep the water temperature relatively constant, reduce the environmental impact, and perfectly solve the problem of the past calorimeter after 4~5 experiments. The water temperature in the barrel exceeds 1.5 °C at room temperature, which leads to a common problem that cannot be continuously tested (the national standard requires that the temperature of the barrel and the room temperature should not exceed 1.5 °C during the experiment), which makes the experimental results more accurate and truly exerts the advantage of full self-control.
TIPS: JL-1A building material combustion calorific value tester and JL-1B building material combustion calorific value tester function difference is that JL-1B building material combustion calorific value tester has constant temperature cooling function to ensure the water temperature in the test space is not Affected by the test, ensuring the accuracy of multiple tests.
