Fully‑Automatic Calorimeter for Fuel‑Oil Combustion Calorific Value

Touch‑Screen Fully‑Automatic Calorimeter for Fuel‑Oil Combustion Calorific Value

This calorimeter for fuel‑oil combustion calorific value complies with GB/T 384, the national standard for testing the calorific value of petroleum products. It is used to determine the calorific value of various fuel oils, including petroleum, light oil, heavy oil, diesel oil, coal tar, asphalt, alcohol, chemical‑process oil, paraffin oil, castor oil, orimulsion, pyrolysis tyre oil, vegetable oil, furnace fuel oil, naphtha, alcohol‑based fuels, methanol fuels and other combustible solid or viscous liquid substances. It is also suitable for new‑energy, electric‑power, coal, metallurgy, petrochemical, quality‑inspection, environmental‑protection, cement, papermaking, geological‑prospecting, scientific‑research institutes and other industrial sectors, for measuring the calorific value of combustibles such as biomass new‑energy materials, building thermal‑insulation materials, coal and petroleum.

Functional Features

1. Adopts American‑style embedded technology, with a 7‑inch large‑size full‑color touch‑screen operated by integral mounting structure to ensure firm installation of the touch screen.

2. CRT display material is adopted for enhanced durability of the touch screen. Multi‑layer composite‑film covering guarantees low color distortion, anti‑reflective performance and high definition. It delivers sensitive induction and accurate positioning with high wear‑resistance for effective touch‑operating zones. Chinese‑character display enables direct operation without an external computer.

3. Automatic water‑filling, no manual water‑temperature adjustment required. Simply load the oxygen bomb and place it into the bucket, then the instrument automatically completes the whole test procedure. Rational human‑oriented structure, reliable performance and low failure rate.

4. Chinese menu‑driven operation interface, intuitive, easy‑to‑learn and user‑friendly with stable and reliable performance. Photoelectric isolation is implemented between inner and outer cylinders for strong anti‑interference capacity. Novel foaming thermal‑insulation technology prevents test results from being affected by ambient temperature fluctuations during experiments.

5. Calorific‑capacity repeatability uncertainty: ≤0.2%; precision: ＜0.1%; temperature resolution: 0.0001 K.

6. Excellent performance and operational reliability even under harsh working conditions.

7. Compact and aesthetic configuration, easy installation and maintenance with low failure rate. Built‑in fault‑diagnosis function facilitates operation, together with built‑in ignition‑success / ignition‑failure prompt.

8. Compact footprint, extensively manufactured by moulding process for high machining precision.

9. Superior repeatability and reproducibility of calorific‑value measurement, excellent thermal stability and other performance.
