Automatic Calorimeter

Listing ID #3923658

Description 

It is applicable in the industry such as electrical power, coal, commodity inspection, environmental protection, geological prospecting, metallurgy, papermaking, chemical industry, scientific research, education, etc, and instruction to measure the calorific value of combustible materials such as coal, coke, petroleum, cement black meal.

Features

Using multi-probe real time temperature sensing, it would realize dynamic balance between outer bucket temperature and room temperature. In regard to traditional constant temperature calorimeter, National standard requires that outer bucket temperature should be close to room temperature, and the difference can’t exceed 1.5?. Otherwise test result is invalid, it thus highly affirms that room temperature changes have great influence on the experimental results. In theory , during the test process if the room temperature is higher than outer bucket temperature, outer bucket absorbs heat. If room temperature is lower than the temperature of the outer bucket, outer bucket releases heat. Outer bucket absorbs heat and releases heat , which would make the effect on test result .During the experiment, if room temperature always keep the same as outer bucket temperature, then the experimental results are the best. During test process, the instrument detect and adjust in real time outer bucket, inner bucket ,controlling water tank and room temperature , which is in order to keep room temperature always with outer bucket temperature.

1.CE certificated; exported to European countries.

2.With the special multi-sensors technology, the temperature of inner bucket, outer bucket, ambient, controlling water tank, can be timely monitored. It adopts constant temperature

water circulation system, which will realize two work modes, temperature following and fixed temperature. When it is temperature following mode, water temperature changes with room temperature, which perfectly solves in fixed temperature mode the heat exchange problem of the outer bucket and indoor air during experiment process, eliminating the uppermost factors which would affect the testing results of calorimeter.

3.Adopting unique pump circulation method, which keeps the temperature uniform among the

whole calorimetric system, making sure the accuracy of the testing results.

4. Equipped with the latest oxygen auto oxygen filling facility, and auto elevating system.

All the processes in the experiment are automatic, there is no need to fill oxygen, relief air, high degree of automation, simple and convenient operation.

5. Adopting imported heat insulation material, it effectively isolates from the influence of external environment, anti-interference ability is better.

6. Probe-type electronic measuring cup is used to measure the inner bucket water, repetition error is less than 0.5g, so the water quantity is more accurate and the testing time is shorter.

7. Ignition fuse has the function of automatic discriminating, which accurately judges the poor state of ignition fuse.

8. The special auto stop and auto draining joints are equipped to change the water. When the drainpipe is connected, the instrument discharge water; when the drainpipe is taken off, the water will stop effusing.

9. Using the advanced USB technology, one computer can control 1-4 calorimeter buckets or other instruments, thus to make up synthesized testing instrument.

10. Water path is equipped with standard joint, which would reduce equipment failures.

11. It can link electronic scale and share data in long distance through network.
