Overview
The RI-C5800 determines gross calorific value of coal, coke, oil, biomass, SRF, food and cement raw meal by the oxygen-bomb combustion method. Water quantity is metered automatically by a calibrated volumetric cup, the bomb is filled and lifted automatically, and a built-in refrigeration loop keeps the jacket at target temperature between runs.
A corrosion-resistant triple-thread oxygen bomb accepts biomass and high-ash samples, and the heat capacity drift stays within 0.20 % over a full year — the figure that decides whether your trade-lab results hold up in arbitration.
Key Features
Fully automatic water dosing
Volumetric-cup metering keeps inner-bucket water exactly constant run-to-run — the precondition for repeatable calorific values.
Corrosion-resistant oxygen bomb
Triple-thread bomb with anti-corrosion coating handles biomass, waste-derived fuels and chlorine-bearing samples without pitting.
Audit-ready software
Operator login levels, tamper-proof records, automatic raw-data backup and upload — ready for fuel-management and LIMS integration.
Single or dual control
Choose one or two thermostats on one controller. Dual-control doubles throughput for commercial labs with peak loads.

Standards: what each number covers
Buyers compare instruments by standard number, then have to look up the title and the relationship. This table does that for you. “Declared” means the method is named for this model; “equivalent” means the method is compatible in principle and must be verified against your own procedure; “referenced” means the standard supplies qualification or test conditions rather than the measurement itself. Final method compatibility depends on the configured instrument and your written test procedure.

Frequently Asked Questions
What is the difference between isothermal and adiabatic bomb calorimeters?
An isothermal (static-jacket) calorimeter holds the water jacket at a near-constant temperature and corrects for the heat exchanged between bomb and jacket during the burn, using a pre-determined cooling constant. An adiabatic calorimeter actively heats the jacket so it tracks the bomb temperature, so there is no jacket-to-bomb heat leak to correct. Isothermal designs are simpler to maintain and easier to verify with a reference material; adiabatic designs need a jacket-control loop and a well-characterised adiabaticity. Under ISO 1928 or ASTM D5865, either design can be used — what matters is that the effective heat capacity, the jacket correction and the thermometer resolution are established and controlled in your own laboratory.
Do I need ISO 1928 and ASTM D5865 at the same time?
Only if you report to buyers who name different standards. Both define gross calorific value from a bomb-combustion measurement; the differences that matter in practice are the reference temperature, the treatment of the acid and fuse corrections, and the calculation basis for net calorific value. Decide which standard governs your reporting, then confirm the instrument configuration and the certification of the reference material against it — do not assume that a result obtained under one is automatically accepted under the other.
Why do two calorimeters give different calorific values for the same sample?
Most disagreements come from four places, not from the instrument: (1) sample preparation — moisture uptake or incomplete mixing of the analysis sample; (2) the heat-capacity determination, including whether it was done at the same temperature band as the test; (3) the fuse-wire and acid corrections, especially when the combustion is incomplete; and (4) the thermometer calibration traceability. A useful arbitration procedure is: run the same reference material on both units on the same day, then compare against the certified value before comparing samples with each other.
Which standards are declared for the RI-C5800, and are they equivalent or directly declared?
RI-C5800 is listed with: ISO 1928:2009 (declared compliance); ASTM D5865-13 (declared compliance); GB/T 213-2008 (declared compliance); CEN/TS 14918 (declared compliance); BS EN 15400 (declared compliance); JJG 672-2018 (declared compliance). The standards table below shows what each number covers. Final method compatibility depends on the configured instrument and the customer's written test procedure.
