Performance Features

1. Electronic refrigeration technology, unaffected by changes in ambient temperature, ensures the temperature difference between the inner and outer buckets meets requirements, allowing continuous long-term operation.

2. Automatic oxygen bomb lifting, automatic oxygen filling pressure detection, automatic oxygen bomb airtightness detection, automatic inner bucket water volume setting, automatic inner bucket water temperature adjustment, and automatic experiment completion; supports both ignition wire and cotton thread ignition methods; inner bucket circulating water system, easier disassembly and assembly with a new stainless steel oxygen bomb and metal inner bucket for rapid direct volume setting, supplemented by a stable new inner bucket stirring method, faster heat transfer of the oxygen bomb, effectively shortening test time, continuous testing with single sample test time <18min; (Rapid method) Equipped with a semiconductor temperature-controlled constant temperature water tank, offering more precise water temperature control, lower overall power consumption, and lower noise compared to conventional compressor-cooled water tanks.

3. Fast testing speed, test cycle: rapid method ≤8min, national standard method ≤17min.

Heat capacity stability <0.2%, precision <0.1%, temperature resolution 0.0001K.

4. This product delivers excellent performance and reliability even in harsh environments, with a compact structure, aesthetically pleasing design, easy installation and maintenance, low failure rate, small size, extensive use of mold manufacturing, and high precision.

5. Repeatability and reproducibility of calorific value testing comply with GB/T213-2008 requirements; high degree of automation, automatic use of built-in constant volume inner bucket water volume, automatic control of temperature difference between inner and outer buckets, automatic completion of the entire test process.

6. Utilizes Windows operating system, enabling one machine to control multiple units with independent testing processes, ensuring high software stability.

7. Rich data processing functions, allowing users to easily query historical test data, daily data, parallel sample data, etc.

8. Uses original imported stirring motors, ensuring uniform and stable stirring, reliable performance, and strong anti-interference capability. Achieves automatic water filling, automatic water temperature adjustment, automatic quantification, automatic stirring, and automatic ignition, reducing human error.
