WJR - 200 am oxidation induction time testing machine         
Product introduction:
Oxidation induction time machine is under program control temperature, the material oxidation induction time of professional equipment, is a professional instrument measuring pipe oxidation induction period.Can automatically record pipe, material at a constant speed in nitrogen atmosphere heating style and the reference material, when reached the specified temperature, switch to the same velocity of oxygen atmosphere.After sample at the temperature constant temperature until the show on curve of thermal oxidation reaction.Starting from the oxygen flow into the moment, oxidizing reaction to the time interval, both for the oxidation induction period.Instrument can automatically record the oxidation induction period, temperature, time curve can also be measured between the substance and reference substance temperature difference and temperature.Automatic record description between the sample and reference temperature (delta T) along with the change of temperature or time.Can also detect phase transition, melt, the change of crystalline structure, boiling, distillation, evaporation and dehydrogenation reaction, fracture or decomposition reaction, oxidation and reduction reaction, the destruction of the lattice structure and other chemical reactions.

The instrument features
1, specially designed for measuring the oxidation induction period design plastic, rubber industry, machine integration, reducing the loss of signal, reduce the interference.
2, sample above the instruments, easy to operate.
3, miniaturization, heating furnace, reducing thermal inertia, the samples from room temperature can guarantee to linear temperature, constant temperature control more accurate.
Two road 4, perfect atmosphere control system, the mass flow controller.Measurement process, nitrogen, oxygen, automatic switching.
5, user using standard sample temperature, constant temperature coefficient of correction can be performed, reduce the error.
6, can automatically detect the oxidation induction period data and automatically generated curve.
7, can automatically make a tangent, intersection and can directly get the actual time of the intersection to the nitrogen oxygen switch.
8, instrument can automatically generate oxidation induction period experiment report.
9, large screen LCD, real-time display of the instrument condition and data, two sets of temperature measuring thermocouple, a set of galvanic real-time display temperature (regardless of the heating furnace work or not) another set of galvanic couple sample temperature display work.
10, user gives a calculation formula and calculation method, our factory can provide the corresponding software development products.
11, instrument has the function of remote operation and maintenance, calibration (via the Internet to remote operation instrument).
