Well-known calorimeters are key testing equipment in the fields of energy, chemical industry, scientific research, etc. The core function is to accurately measure the heat changes in the process of material combustion and reaction, and provide data support for experimental analysis and production control. The following are the mainstream types and representative equipment:
1. Oxygen bomb calorimeter
This is one of the most widely used calorimeters, represented by German IKA and American PARR. Its core principle is to fully burn the sample in high-pressure oxygen through an oxygen bomb, and absorb heat with the help of a water bath to accurately calculate the calorific value. This type of equipment has high precision and is suitable for solid and liquid sample detection. It is often used in the determination of calorific value of coal and fuel oil. It can meet the national standard testing requirements and is standard in energy testing laboratories.
2. Adiabatic calorimeter
Representative brands include Shanghai Changji and Changsha Sande. It ensures the constant temperature of the measurement environment by isolating external temperature interference and reduces the impact of temperature fluctuations on the results. The equipment is highly automated and easy to operate, suitable for scenes with strict accuracy requirements, such as explosives and new energy materials. It is widely used in military and scientific research fields and has strong detection stability.
3. Microcomputer automatic calorimeter
Domestic brands such as Beijing Zhuoxin and Nanjing Broadcom have outstanding advantages and integrate into the microcomputer control system to automate the whole process of ignition, temperature measurement and calculation. It can not only display data in real time, but also automatically generate reports, greatly reduce manual operation errors, adapt to batch sample testing, and have extremely high efficiency in raw material testing and batch inspection of quality inspection agencies in chemical enterprises, taking into account accuracy and convenience.
4. Cryogenic calorimeter
Represented by TA instruments from the United States and Shimadzu products from Japan, it is specially designed for low temperature environmental heat detection, which can accurately capture the weak heat changes at low temperatures. This type of equipment is mostly used for low temperature performance research of materials and low temperature reaction monitoring of biopharmaceuticals. It can provide fine data for scientific research and is indispensable in the field of cutting-edge scientific research.

When selecting a well-known calorimeter, it is necessary to combine the testing requirements: if it focuses on conventional energy detection, oxygen bomb or microcomputer automatic calorimeters are more suitable; if it involves low temperature or high-precision scientific research, low temperature calorimeters and adiabatic calorimeters are preferred, and attention should be paid to the detection accuracy, stability and brand after-sales guarantee of the equipment.
