Calorimeter features and working principle

Calorimeter, also known as calorimeter, is used to measure the calorific value of orange bar, coal and petroleum, and is used in thermoelectricity, cement, coal, new energy and other fields.

The working principle adopts the advanced single-chip microcomputer system, the operation is fully automatic, the manual only needs to do the weighing, the loading and the oxygenation, the instrument automatically completes the quantitative water injection, the automatic stirring, the ignition, outputs the printing result, the drainage and so on the calorimeter of the calorimeter In the system, except that water absorbs heat, oxygen bombs, inner cylinders, thermometers, stirrers, etc. absorb heat, and their respective endothermic conditions are not the same. Various factors are more complex and cannot be obtained by simple mathematical calculations. The reference calorimeter with known calorific value such as benzoic acid is used to actually calibrate the calorie to be absorbed when the calorimetric system temperature is increased by 1°C, that is, the heat capacity of the calorimeter is calibrated.

The heat capacity calibration is valid for 3 months, but should be recalibrated immediately when:

1. The calorimeter in normal use has been moved to a greater extent;

2. Replace the larger parts of the calorimeter bomb: such as oxygen bomb caps, connecting rings, etc.;

3, change the calorimeter thermometer;

4. When measuring the calorific value, the actual inner water temperature of the inner cylinder is different from the average inner cylinder temperature of the heat capacity by more than 5°C;

5, after the calorimeter overhaul, and completely change the water; calorimeter network suggested that if the use of calorimeters for a long time no significant changes in the environment, each year according to the use of the seasonal changes, divided into spring, summer, In autumn and winter, each calibration is once.

Automatic calorimeter features Ultra-large capacity water tank, suitable for high-volume continuous 24-hour experiment using advanced single-chip microcomputer system, fully automatic operation, manual only need to do weighing, loading and oxygenation, the instrument automatically completes quantitative water injection, automatic mixing , Ignition, output printouts, drains, etc.

Human-computer interaction interface is friendly, large-screen Chinese characters screen display time and test process, that is, learning to use has the function of converting high and low level heat after the experiment.
