TRHW-7000AB fully automatic lifting isothermal calorimeter Introduction: This instrument is suitable for measuring the calorific value of solid or liquid combustibles such as biomass fuels, waste fuels, coal, petroleum, cement black raw materials, grains, feed, etc. in industries or departments such as electricity, coal, metallurgy, petrochemicals, coalification, environmental protection, cement, papermaking, geological exploration, agriculture and animal husbandry, pharmaceutical research, and teaching. characteristic: 1. The electronic refrigeration process is not affected by changes in ambient temperature, ensuring that the temperature difference between the inner and outer barrels of the instrument meets the requirements and can work continuously for a long time. 2. Automatic lifting and lowering of oxygen bombs, automatic oxygen filling and discharging, automatic detection of oxygen pressure, automatic detection of oxygen bomb airtightness, automatic constant water volume in the inner bucket, automatic adjustment of inner bucket water temperature, and automatic completion of experiments; 3. Fixed volume oxygen bomb, constant volume, automatic recognition of oxygen bomb; 4. Supports two ignition methods: ignition wire and cotton thread 5. Fast testing speed, fast testing cycle ≤ 12 minutes, national standard method ≤ 15 minutes. Thermal capacity stability<0.2% precision<0.1% temperature resolution 0.0001K 6. This product has good performance and reliability even in harsh environments, with a compact structure, beautiful appearance, easy installation and maintenance, low failure rate, small size, extensive use of molds for manufacturing, and high precision. 7. The repeatability and reproducibility of the heat generation test meet the requirements of GB/T213-2008, with a high degree of automation. It automatically utilizes the water volume in the built-in fixed container, controls the temperature difference between the inner and outer buckets of the instrument, and completes the entire test process automatically. 8. Adopting the Windows operating system to achieve multi control on one machine, mutual testing without affecting each other, and high software stability. 9. The data processing function is rich, and all data is authentic and reliable. No software correction is used to change the test results. Users can easily query historical experimental data, current day data, parallel sample data, etc. 10. Adopting the original imported mixing motor from Japan, the mixing is uniform and stable, with reliable performance and strong anti-interference ability. Realize automatic water filling, automatic water temperature adjustment, automatic metering, automatic mixing, automatic ignition, and reduce human error. 11. Outer cylinder constant temperature control method: heating and semiconductor cooling. The outer cylinder water temperature fluctuates by ≤± 0.02 ℃ throughout the day, and the fluctuation during the single sample test period is less than 0.01 ℃. The outer cylinder does not require additional cold water for cooling, and the water systems of the inner and outer barrels are independent of each other. Quantitative method for inner bucket water: Quantitative water cup Technical parameters: Operating temperature range: 0-60 ℃ Precision: ≤ 0.10% Temperature resolution: 0.0001 ℃ Continuous testing sample quantity: unlimited. Accurate testing of first and interval samples Oxygen bomb capacity: 300ml Oxygen bomb pressure resistance: 30MPa Power supply voltage: 220 ± 10% 50Hz Environmental humidity: ≤ 85% Thermal capacity stability: ≤ 0.20% within one year Accuracy: Difference in calorific value from benzoic acid standard ≤ 50J/g (average of 5 times) Ignition method: ignition wire Testing time: Rapid method ≤ 8min, National standard method ≤ 15min Power supply: 220V ± 22V, 50HZ ± 1HZ Power: ≤ 0.8KW Blender: speed 400-600r/min, continuous stirring for 10 minutes generates ≤ 120J of heat
