Introduction
An oxygen bomb calorimeter is an instrument used to measure the heat of combustion of a substance, which is the amount of heat released when the substance is burned completely in oxygen, and it is used for the analysis of fuels, foods, and other combustible materials in the energy, food, and research industries. The oxygen bomb calorimeter consists of a bomb, or a sealed vessel, in which the sample is placed with an ignition wire and filled with oxygen under pressure, a calorimeter vessel with a known amount of water, a stirrer, a thermometer or temperature sensor, and an ignition system; in operation, the sample is weighed and placed in the bomb, the bomb is filled with oxygen and sealed, the bomb is placed in the calorimeter vessel with the water, and the sample is ignited electrically, and the heat released by the combustion is absorbed by the water, and the temperature rise of the water is measured, and the heat of combustion is calculated from the temperature rise and the heat capacity of the calorimeter; the oxygen bomb calorimeter provides an accurate measurement of the heat of combustion, expressed in joules per gram or calories per gram, following standardized methods, such as ASTM D240; the oxygen bomb calorimeter is used for the determination of the calorific value of fuels, such as coal, oil, and gas, for the analysis of the energy content of foods, for the analysis of waste materials, and for many other applications. Oxygen bomb calorimeters are used in the energy industry, in food analysis, in research laboratories, in quality control, and for many other applications. With their measurement of the heat of combustion, oxygen bomb calorimeters are essential for calorific value analysis.

FAQ
Q1: What scenarios is this calorimeter used for?
A: It measures the calorific value of coal, fuels, biomass and waste by combusting a sample in an oxygen-filled bomb under controlled conditions, reporting energy content.
Q2: What standards does it comply with?
A: It follows ASTM D5865 and D240, ISO 1928 and related GB/T standards, with the bomb pressure-tested and temperature calibrated.
Q3: What is the warranty?
A: The calorimeter carries a 12 to 24 month warranty covering the instrument. The bomb requires periodic pressure testing. Damage from misuse or over-pressure is excluded.
Q4: Is it hard to operate?
A: Operation requires trained staff for oxygen handling, bomb assembly and safety. We provide a manual, installation and training.
Q5: What is the lead time?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is calibration required?
A: We recommend verification against traceable standards at regular intervals, typically every 6 to 12 months, and keeping calibration records for audit purposes. The manual describes the procedure, and reference standards are available from us. Accredited third-party calibration can also be arranged on request.
Q7: Are consumables universal?
A: Benzoic acid and ignition wire are standard, while bomb parts are model-specific. Ongoing cost includes wire and oxygen.
Q8: Can it be customized?
A: Yes, several configurations are available. Options include manual or automatic water handling, autosamplers and data software. We can discuss further custom requirements, confirm feasibility and advise any effect on the schedule before the order is confirmed.
Q9: Is installation included?
A: Standard delivery includes the calorimeter and manual. On-site installation and training are typically included or recommended.
Q10: What samples are compatible?
A: It handles combustible solid and liquid samples within the bomb and method. It is not for explosive or reactive samples beyond safe limits, non-combustible materials, or samples producing dangerous acids without proper handling.
