ST-500 Food and Feed Calorimeter
Overview:
The ST-500 food and feed calorimeter is a multifunctional
calorimeter developed using a single-chip microcomputer. It is
mainly used for measuring the calorific value of solid and liquid
combustibles such as coal, petroleum, food, wood, and other
substances. This instrument uses a high-precision microcontroller
calculation program to greatly improve measurement accuracy. It
adopts a liquid crystal display, fully displays in Chinese, is easy
to operate, and can achieve automatic control of the measurement
process. It can automatically add water, drain water, ignite, stir,
calculate, and print the calorific value of the measured substance.
The experimental results are clear at a glance. It is an ideal
laboratory equipment developed for enterprises and universities
engaged in the production and research of flammable substances.
Digestive energy refers to the energy contained in digestible
nutrients in food and feed, which is the difference between the
total energy of animal feed intake and fecal energy. Under normal
circumstances, animal feces mainly include the following substances
that can generate energy:
● Undigested and unabsorbed nutrients
● Digestive tract microorganisms and their metabolites
● Digestive secretions and metabolic products excreted through the
digestive tract
● Total energy of exfoliated cells in the digestive tract mucosa
FEATURES:
● This machine is composed of a high-end microcontroller, with a
simple structure, reliable performance, and strong
anti-interference ability.
● The automatic addition of water, drainage, mixing, ignition,
temperature measurement, calculation, calibration, printing, and
experimental processes have achieved full automation, avoiding
human errors and greatly improving accuracy and precision.
● Automatic cooling calibration for experiments, with relaxed
requirements for environmental temperature, improves experimental
accuracy while ensuring the stability of the instrument during
long-term operation.
● After the experiment, it can automatically convert the high and
low heat generation of printing, which is more in line with general
conventional experiments.
● Full Chinese display, easy to operate.
