calorimeter

an instrument for measuring quantities of heat, e.g. a BOMB CALORIMETER measures the heat output on burning a sample of material. Calorific values used in energetics are now measured in JOULES rather than CALORIES.

Fitting this distribution with suitable function will give energy resolution value for the interested calorimeter setup.
The dynamics of the calorimeter are limited by the time delay between the input current of TEM and the associated heat pump rate.

The results revealed that the calorimeter gelatinization temperatures and the enthalpy values of the tapioca starch mixtures increased and decreased significantly, respectively, with increasing xanthan gum content.
The cone calorimeter (Stanton Redcroft, UK) tests were performed according to ISO 5660 standard procedures.
The EM calorimeter has high precision both in the amount of energy absorbed and in the location of the deposited energy.
Figure 1 shows a diagram of the previous NIST high-power laser detector calibration system in which a WTM was used as a beamsplitter to provide simultaneous beams to the device under test (DUT) and the primary standard calorimeter. In order to obtain the desired power-splitting ratio of the transmitted to the reflected beams, materials with the appropriate index of refraction at the operating laser wavelength were used.
It was observed however, during repeated calorimetric experiments, followed by frequent chemical composition analyses, that the composition of the residual gas from the calorimeter does not obey the chemical equilibrium at room temperature, but at an unexpectedly high temperature instead (Rugescu, 2005).
The U-factor of each glazing product as mounted in the solar calorimeter surround panel was determined using the Window 4.1 (LBNL 2004) program and the Frame 4.0 (Enermodal 2004) program following the NFRC 100-1991 procedure (NFRC 1991).
Built initially for the company's own use, the TFC-9000 thin-film calorimeter measures heat generated by the curing reaction.
Only a month after its July 10th launch, the Japanese/American Suzaku X-ray observatory (formerly known as Astro-E2) lost the use of its X-ray Spectrometer (XRS), the first high-energy calorimeter to fly in orbit and the mission's flagship instrument.
The method of evaluating fire-retardant material was also changed and the cone calorimeter test was adopted.
