ECO Calorimeter

A small, desktop apparatus, in a warm buttercup yellow. It performs the temperature analysis of a sample. The operator, balance, vessel and PC interface together. It is insulated against ambient temperature changes via an "air barrier" and polystyrene. The ambient temperature is measured. It "fires" the sample by heating the firing wire inside the vessel.

The ECO has been designed for the low volume market and is most suitable for customers running less than 8 CV samples per day.

The Vessel

The CAL2K-4 Vessel is the first of its kind and is the heart of the CAL2K System.

Its sophisticated design allows the temperature to be measured to five decimal places in degrees Celsius. The vessel is an intelligent (SMART) vessel with a microprocessor built into its base. The vessel is capable of : firing counts, identification, memory and reconditioning data.

The vessel is the combustion chamber. It is made of stainless steel and tested up to a pressure of 300 atmospheres (4200psi).

The Filling Station

The Filling Station is designed to fill the vessel with oxygen to 3Mpa.

The filling rate is controlled so as not to disrupt the sample in the crucible. The Filling Station is extremely easy to operate and requires minimal adjustments and maintenance.

Animal Feed Research

Food calories are measured in KJ/g, the same as combustible calories. However, the process is different, although the outcome is the same : KJ/g or heat, or calories. Animal feed stock relies on the animal digestion (conversion). A calorimeter burns the lot and measures the released heat. Then a calorimeter can't be used to measure feed stock?

Coal & Coke Analysis

The coal industry is the traditional application of calorimeters because coal has a variety of properties, apart from being black. If the coal is used for steam generation then the calorific value is of paramount importance. The calorific value, short CV, is a measure of how much heat can be extracted from it.

View Application
Explosives Analysis

Only explosives which can be ignited by heat from the calorimeter's firing circuit can be tested in the oxygen calorimeter. Then very minute/small quantities are used for analysis. The calorific value of an explosive is not very high, but the burning speed is.

View Application
Fuel Analysis

As a general rule, volatile fuels are measured very seldom because they are very consistent. However, if the fuel absorbs water, then frequent analysis is called for. Volatile fuel such as alcohol must be prevented from evaporating during the handling process that is from weighing to ignition of the sample.

Food & Nutrition Analysis

Here is an example of food calories from As the article says : "The method of using a combustion calorimeter to measure food calories is not frequently used today. However, after some considerations it can, and is, used today for checking the production quality of food." Let's look at the details.

Oil Analysis

Oils are a non-volatile substance. In general they are not measured frequently because they are very consistent and uniform. Other oil properties are more important than the calorific value, such as taste or viscosity. If an oil is measured in an oxygen calorimeter, then the procedure would be the same as a solid substance.

Waste Product Analysis

Heating energy is being dumped on our municipal landfill sites. Our landfill sites are being clogged by plastic waste, which battle to bio-degrade over time. Alternative options for managing plastic waste has been identified as mechanical recycling, cement kilns, power station and energy recovery by incineration. Having plastic on landfill sties should be the last option.

CAL3K-U Oxygen Bomb Calorimeter System | DDS Calorimeters


The oxygen bomb vessel is smaller than the conventional vessels, which results in a smaller heat capacity. Special attention has been given to a thermally balanced vessel desgin which has been achieved using computer aided design (CAD) and computer simulation of heat transfer characteristics.
