Digital Display Differential Scanning calorimeter DSC Oxygen Induction Time OIT

 

1. Application:

The differential scanning calorimeter is a new type of thermal analysis instrument with the three major characteristics of intelligence, miniaturization, and unit combination. It is widely used in material melting, solidification, decomposition, compounding, reductive oxidation, crystallization, phase diagram production, and the development of catalysts. It is the main analysis method in organic, inorganic, polymer, mineral, petrochemical, textile, pharmaceutical and other aspects. , Has a convenient computer data processing system. With various analysis software, such as epitaxial starting point temperature, enthalpy variable, glass transition temperature, enthalpy change ratio, oxidation induction period, and various calculation methods of kinetic parameters, and apply various software skills, arbitrarily zoom in or zoom out Functions, making the overall interface friendly and easy to operate

1.2. The differential scanning calorimeter is composed of the host, small heating furnace, microvolt amplifier, A/D converter, data acquisition system, cooling system, gas flow control system, temperature measurement using thermocouple method, real-time sample collection in the program temperature Changes under control (endothermic or exothermic), temperature control adopts platinum resistance method, the host window is displayed on the LCD, and the current working condition can be displayed in real time without turning on the computer; the panel button can carry out the temperature "heating, constant temperature, stop" The temperature can be tracked by pressing the "heat up" button during the second temperature rise; the gas flow can be switched and closed by pressing the button "nitrogen, oxygen, and gas off"; the computer adopts USB communication (desktop computer, laptop computer), It is composed of printer and other parts, and each part is connected by special connectors, which is convenient for installation and maintenance.
