I. scope of application
Test instrument for testing the combustion performance of plastics and non-metallic materials.Applicable to the laboratory method for determination of horizontal or vertical combustion performance of samples of plastic and non-metallic materials under 50W flame conditions.(the real object is like the picture on the right)
II. Product features
1. Programmable controller touch screen +PLC control, realizing multi-function of control/detection/calculation/data display.
2. High degree of automation: automatic recording of test time, automatic display test results, automatic timing, automatic ignition, Bunsen lamp will automatically return after the end of the flame, and you can choose whether to turn off the gas.
3. Automatic ignition can be selected during startup.
4. Style clip front, back, up, down advance and retreat can be controlled by touch screen, start, stop, gas, timing, ignition, save, save, lighting and exhaust are all realized by touch screen control, the test can be completed by fingertip touch.
5. Timing button and PLC automatically record the storage and combustion time.
6. Test time system automatically records and generates test results.
