Suitable for enterprises, schools, research departments, and military units engaged in the production, research, and use of combustible materials to determine the calorific value of coal, coke, and other combustible materials, as well as the explosive calorific value of gunpowder.

Technical parameters:
■ Measurement accuracy: superior to national standards
■ Operating environment: 5-40 ℃ (temperature change should be ≤ 1 ℃ per measurement) Relative humidity ≤ 80%
■ Temperature resolution: 0.0001 ℃
■ Electricity Source: AC220V ± 15% 50Hz

Performance characteristics:
■ Adopting a compressor refrigeration method, the temperature of the inner and outer cylinders is automatically adjusted to reduce the cooling correction factor, making the measurement results more accurate.
Meet the national standard requirement of 'the inner cylinder is about 1K higher than the outer cylinder at the endpoint'.
■ The microcomputer calorimeter maintains all the functions of the microcomputer system, can run general software simultaneously for other transaction processing, and can automatically calibratecalorimeterThe system's energy equivalent (heat capacity) and measured heat generation. Input data such as sulfur, moisture, hydrogen, etc. to convert and print out data such as cylinder heat generation, high-level heat generation, low-level heat generation, etc.
■ calorimeterThe inner cylinder of the device adopts electric stirring with sheet-like blades, while the outer cylinder adopts submersible electric stirring, making the stirring more uniform and convenient. The instrument adopts a fused cotton thread ignition method.
■ MicrocomputercalorimeterRun on Winsows98 and above operating systems, with Chinese character prompts and human-computer interaction throughout the entire process, ready to learn and use. Follow the prompts to complete the experiment.

■ The unique water circulation system ensures that any external debris will not have any impact on the circulating water pump.
