Performance Features ：
■ It adopts an automatic variable frequency refrigeration method, automatically adjusts the temperature of the inner and outer cylinders, reduces the cooling correction coefficient, and makes the measurement results more accurate. It adopts a unique refrigeration temperature control system, making the temperature rise and fall during the experiment zero. It ensures the stability and accuracy of the experimental results. The unique semiconductor refrigeration type water circulation system can determine the cooling capacity based on the previous heat generation, balance the circulation water system, keep the water temperature relatively constant, and reduce the environmental impact It has perfectly solved the common problem that the water temperature in the outer bucket of the calorimeter exceeded the room temperature by 1.5℃ after 4 to 5 consecutive experiments in the past, which led to the inability to conduct continuous experiments (the national standard requires that the temperature of the outer bucket and the room temperature should not exceed 1.5℃ during the experiment), making the experimental results more accurate and truly bringing out the advantages of the fully automatic calorimeter.
■ The water temperature of the refrigeration water tank was adjusted to the set temperature in advance and stirred evenly, which shortened the preparation time before the ignition of the oxygen bomb and improved the test speed. Stainless steel vacuum inner cylinder. The stirring system adopts the original imported motor from Germany. Heat capacity stability < 0.2%, precision < 0.1%, temperature resolution 0.0001K. This product maintains excellent performance and precision even when operating in harsh environments. Compact structure, beautiful appearance, easy installation and maintenance, and low failure rate. Compact in size, it is manufactured extensively with molds and features high precision. It features a high degree of automation, automatically utilizes the water volume in the built-in fixed container bucket, automatically controls the temperature difference between the inner and outer buckets of the instrument, and automatically completes the entire testing process. A new automatic temperature compensation function has been added to ensure the instrument can work for a long time and reduce the frequency of instrument recalibration. New intelligent frequency conversion technology has been added to save electricity intelligently. The automatic ignition wire discrimination function accurately determines the poor condition of the ignition wire. A new biofuel testing function has been added, solving the problem of easy splashing during biofuel testing. The data processing function is rich, allowing users to conveniently query historical test data, current day data, parallel sample data, etc.
■ It complies with the provisions of the national standard GB/T213-2008, which states that "at the endpoint, the inner cylinder is about 1K higher than the outer cylinder."
■ The high-precision microcomputer fully automatic calorimeter retains all the functions of the microcomputer system. It can run general software to handle other affairs. Meanwhile, when the calorimeter measurement system is started, it can automatically mark the energy equivalent (heat capacity) of the calorimeter system and measure the calorific value. Input data such as sulfur, moisture, and hydrogen, and you can convert and print out data such as the calorific value of the cartridge, high calorific value, and low calorific value.
■ The inner cylinder of the calorimeter device adopts electric stirring with flaky blades, and the outer cylinder adopts submersible electric stirring, making the stirring more uniform and convenient. The instrument adopts a fusible cotton thread ignition method and supports two ignition methods: ignition wire and cotton thread. The microcomputer calorimeter operates on Windows 7 or above operating systems. The entire process features Chinese character prompts and human-computer interaction, making it easy to learn and use. Just follow the prompts to complete the test. Standard configuration
It is equipped with one computer, one printer, one oxygenator, one pressure reducer, one oxygen bomb, one bottle of potassium benzoate, five stainless steel crucibles or quartz crucibles, three sets of oxygen bomb sealing gaskets, and two rolls of ignition wire.
