What exactly is a bomb calorimeter
Bomb calorimeters are used to precisely calculate the energy shift that occurs during a reaction. The original Berthelot calorimeter was developed into the contemporary Bomb calorimeter. The combined bomb calorimeter of today is constructed of corrosion-resistant steel.
An apparatus known as a bomb calorimeter is used to measure the heat of reaction at a constant volume and the measured heat, also known as the change of internal energy (E). Chemistry allows for the measurement of a reaction's heat changes at a fixed pressure or volume.
How a Bomb Calorimeter Works
The combustion heat of samples that can burn with oxygen is measured using a specific kind of constant-volume calorimeter called a bomb calorimeter. Four crucial components are

SPD-V010 Handheld Roll Gap Checker


Overview



The handheld roll gap checker is specially used to measure the length between spherical surface, arc surface and plane (or spherical surface). It is specially suitable for the opening adjustment of the roll gap of the metallurgical continuous casters in various specifications, because the roll gap checker has the advantages of high resolution, accurate measurement, stable data and easy to use. Because the opening accuracy of the roll gap checker will directly affect the quality of the casting block, this roll gap checker is an indispensable testing equipment in the continuous casting equipment, which can fully meet the needs of on-site installation testing and use process verification. When the hand-held roll gap meter smoothly passes through the gap between the guide rolls of the continuous casting machine, the upper measuring contact of the hand-held roll gap checker contacts the inner arc roll and the lower measuring contact touches the outer arc roll. The handheld roll gap checker is used in perpendicular to the roll diameter direction, during the pushing process, when the hand-held roll gap meter is in the tangent plane of the upper and lower rolls, the measured value is the smallest at this time, and this value is the roll gap measurement value. The design of the hand-held roll gap gauge ensures that the upper and lower contacts of the roll gap checker can smoothly pass the measured roll along a straight line during measurement.

During the measurement process, the roll gap measuring instrument automatically compares the measured values, and displays the minimum measured value on the instrument display interface, which is the current measured roll gap value.
