Simple, we at Digital Data Systems (DDS) have been making calorimeters for the last 40 years. We have a wealth of technical knowledge and calorimeter experience second to none. We are continuously improving our systems with the latest technology as it becomes available, allowing the students to work on a cost effective, easy to use, easy to maintain, commercially applicable instrument that is going to be in the market for another 40 years. Universities believe in investing in the future and we at DDS believe in investing in universities for the future.

The objective of using an oxygen bomb calorimeter in a university is to teach students about:

• Thermodynamics
• Calorific Value Measuring
• Combustible Energy
• Heat of Combustion
• Calorimetric Constant

The CAL3K Calorimeter range of products is well suited for university and higher learning institutions. Some of the CAL3K calorimeters have multiple operating modes, so it can be Isothermal or Adiabatic or Dynamic type of oxygen calorimeter. An ability to change between modes in one calorimeter enables the students to assess the different Calorimetry standards and how they possibly influence the result.

The CAL3K Calorimeter is extremely safe to operate, giving the students piece of mind, allowing them to concentrate on their experiments. The bomb vessel has a quick thread locking mechanism which extends the life of the bomb vessel and reduces maintenance/running costs. The bomb vessel is also smaller and lighter in weight, facilitating less operator fatigue and easier to open and close.

The new waterless air cooler for the CAL3K Calorimeter is another reason why these calorimeters are suited for university laboratories. No water is required at all in the operation of the CAL3K system. No water means no leaks and no extra plumbing, making it easier to install and move around if required. The cooling speed of the waterless air cooler is 6-8 minutes. Not as quick as we would have liked it, but sufficient. If it is too slow, you can use two air coolers.

Regardless, if the oxygen calorimeter is in Isothermal or in Adiabatic mode, the ambient temperature and bomb vessel firing temperature are managed by the Ambient Temperature Controller (ATC) unit (CAL3K-A, CAL3K-AP), providing thermal insulation to the bomb. The true magic of the ATC is in it’s design. The ATC is made of lightweight material, allowing the ATC to rapidly respond to the rising bomb temperature when it is fired.

For university laboratories that require two or three quick results in a row, the CAL3K oxygen calorimeter is your answer. It is the only oxygen bomb calorimeter of its kind that does not need the bomb vessels to be at room (ambient) temperature. The calorimeter can fire a bomb vessel two or three times (depending on the ambient temperature) in a row without cooling the bomb vessel in between. This basically means, with a single bomb vessel you can fire three samples in under 14 minutes. Great for a lecture.

A CAL3K calorimeter is a sensible and very accurate (0.00001C) temperature measuring device, ideally suited for universities and their students. For this reason, all of the DDS Oxygen Calorimeters have a real-time data output for post analysis calculations and spread sheet analysis. The bomb vessel and ambient data are available every 6 seconds together with calibration data and other relevant information. The data provided by the CAL3K calorimeter is intended for the student to solve their experiment and to perform their own calculations.

PUBLISHED EXPERIMENTS

The CAL3K lends itself to being used for university experiments because of the machine’s ability to change operating modes. There are equal amounts of experiments out on the Internet that require either Isothermal or Adiabatic type oxygen bomb calorimeters. The CAL3K-A / CAL3K-AP can work in either Isothermal or Adiabatic, or a mixture of both.
