- Product description
-
Calorimeter is designed to measure the heat of combustion of solid and liquid fuels such as:
- Peat,
- Brown coal,
- Hard coal,
- Brown coal briquette,
- Hard coal briquette,
- Coke,
- Semi-coke,
- Fine coal (also mixed with other substances),
- Oil-derivative fuels and other liquid and semi-liquid ones,
- Biofuels,
- Biomass (in a form of: granulated products, briquettes, chips, pellets),
- Waste materials,
- Different inexplosive, organic and synthetic substances in solid and liquid form.
The measuring method is compliant with Polish Standard. The measurement consists in complete combustion of fuel sample in pressurized oxygen atmosphere. The fuel sample is placed in a special calorimetric bomb immersed in water. In this way the measurement of water temperature increase is carried out. The heat of combustion is calculated automatically and displayed on computer’s monitor. The measuring accuracy of temperature increase is 0,001°.
The control unit of the calorimeter is PC computer. All measuring and check functions are completely automatized. Apart from the heat of combustion, also the calorific value is calculated. The results are displayed on a colour monitor and can be saved on a hard disc and printed in a form of measuring protocols. The device is equipped with software compatible with Windows 98/Me/2000/XP/Vista/W7. The computer set is supplied together with DVD-ROM and colour LCD monitor.
NEW! It is possible to replace standard PC computer with notebook.
The calorimeter is delivered as a complete and ready-for-work device. Both, the calorimeter and the calorimetric bomb have relevant test certificates. Thanks to this calorimeter it is possible to obtain the most accurate results of temperature increase and thus of a calculation of heat of combustion and calorific value.
Computer program and LCD monitor ensure comfortable working conditions. The results of measurements and calculations are saved by the computer and can be printed if need be.
