Touch screen type
Specially tested for oxidation induction of polymer materials, customer one click operation, software fully automatic operation, instrument in compliance with GB/T19466.3-2004 ISO11357-3:1999 Part 6 Oxidation Induction
Determination of oxidation induction time (isothermal OIT) and oxidation induction temperature (dynamic OIT).
FEATURES
1. Industrial grade widescreen touch structure with rich display information, including set temperature, sample temperature, oxygen flow rate, nitrogen flow rate, differential thermal signal, various switch states, and zero flow rate.
2. USB communication interface, strong universality, reliable and uninterrupted signal, supports self recovery connection function.
3. The furnace structure is compact, and the heating and cooling rate can be adjusted arbitrarily.
4. Improved installation process, all adopt mechanical fixation method, completely avoiding the contamination of differential thermal signals by colloids inside the furnace body.
5. Dual temperature probes ensure high repeatability of sample temperature measurement. A temperature probe is installed on the furnace wall for PID control of the temperature of the entire furnace body, but due to the thermal inertia of the temperature,
The temperature transmitted to the sample has a certain deviation, and the deviation is different in spring, summer, autumn, and winter. Therefore, using a single temperature probe for temperature measurement and control, whether it is differential heat signal or temperature signal, the error is not the same
They are all relatively large; This instrument is equipped with an additional temperature probe at the bottom of the sample to measure the true temperature of the sample, and uses our dedicated temperature control technology to control the furnace wall temperature to ensure the sample is in good condition
The product temperature has reached the set temperature.
6. The digital gas quality flowmeter automatically switches between two gas flow rates, with fast switching speed and short stability time.
7. Standard samples are provided as standard, making it convenient for customers to calibrate the constant temperature coefficient.
8. The software adapts to various resolutions of computer screens and automatically adjusts the display mode of each curve according to the size of the computer screen. Supports laptops, desktops, WIN XP, WIN7, WIN8,
WIN 10 for all operating systems.
9. Support user self programming programs to achieve full automation of measurement steps. The software provides dozens of instructions, and users can flexibly combine each instruction according to their own measurement steps and save them. Complex exercises
Simplify it into one click operation.
