HQC-1 HQC-2 HQC-3 HQC-4 automatic microcomputer differential heat meter Introduction
An instrument that measures the temperature difference between a substance and a reference as a function of temperature under programmed temperature control.
HQC-1 HQC-2 HQC-3 HQC-4 fully automatic microcomputer differential heat meter is widely used in the research of basic science fields such as chemistry, physics, geology, biology and chemical industry, metallurgy, geology, electrical engineering, ceramics, textiles , Food, medicine, agriculture, forestry, fire protection and other industries, manufacturing enterprises, scientific research units and colleges.
HQC-1 HQC-2 HQC-3 HQC-4 fully automatic microcomputer differential heat meter is used to study the phase change, decomposition, combination, dehydration, adsorption, analysis, dissolution, solidification, sublimation, evaporation and other phenomena of substances and to identify substances Analysis, component analysis, thermal parameter determination and kinetic parameter determination, etc.
Feature
The furnace body can be lifted and controlled automatically, and the positioning is accurate, which improves the repeatability of the measurement.
The atmosphere control system uses a mass flow controller, and two channels of stable and stable gas can be changed during the experiment, with high accuracy, good repeatability, and fast response (an atmosphere control system that can resist various corrosive gases can be customized).
The entire measurement process is completed automatically, automatic drawing, and DTA routine data processing can be completed using software functions; special data processing (DTA peak area, enthalpy calculation, kinetic parameter calculation, data comparison, multiple algorithms to calculate activation energy, glass transition temperature, Comparative method to measure specific heat, etc.).
During the sample collection process, the system can take screenshots at any time and automatically change the range according to the output signal size.
Users can use their own standard samples such as indium, tin, and lead to calibrate the accuracy of the instrument's temperature and energy.
Large-screen liquid crystal display, real-time display of the instrument status and data, two sets of temperature measuring thermocouples, one set of real-time display furnace temperature (regardless of whether the furnace is working or not), and another set of thermocouples display the sample temperature during work.
The user gives the calculation formula or calculation method, and our factory can provide the corresponding software to develop the product.
Independently developed constant temperature controller; constant temperature gas chromatography, mass spectrometry connector; constant temperature zone; can fully guarantee the secondary detection of tar and various reaction gases.
