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.
Relevant standard GB/T14402-2007 "Combustion performance of
building materials and products - Determination of calorific value
of combustion"

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.
