Non-Combustibility Test Apparatus

TESTech Instrument (Suzhou) Technologies is one of the leading manufacturers and suppliers of non-combustibility test apparatus in China. Welcome to wholesale premium test equipment at competitive price from our factory. If you have any enquiry about quotation, please feel free to email us.

The non-combustibility tester uses a vertical tube furnace to determine the non-combustibility of building materials and to judge whether a material is non-combustible.

The apparatus can fully meet both GB/T 5464 and ISO 1182 international standards at the same time.

The equipment keeps the furnace temperature at 750 +/- 5 degrees C for more than 60 minutes in order to achieve accurate test results.

• Heating furnace: Phi95 mm x Phi75 mm x 150 mm.
• Resistance strip: 3 mm x 0.2 m, nickel 80% and chromium 20%.
• Air flow hood: Phi75 mm x 500 mm.
• Thermocouple: insulated nickel-chromium / nickel-aluminum sheathed type, Phi1.5 mm / Phi0.3 mm.
• Power controller: TP25A.
• Temperature meter: 0 to 1000 degrees C +/- 5%, with temperature measurement accuracy of +/- 0.5%.
• High automation level, safe and reliable testing process, and convenient operation.
• The specimen device is automatically raised and lowered by a motor for safe and reliable operation.
• A high-quality strip heater is used. The furnace temperature can rise to 900 degrees C, and the furnace temperature drift is less than or equal to 2 degrees C within 10 minutes.

• The programmable logic controller (PLC) automates the heating process through modern electronic components, greatly extending furnace service life.
• Thyristor voltage regulation is used, and the PLC output signal controls the heating voltage from 0 to 110 VAC to eliminate the effect of voltage fluctuation on temperature.
• The PLC works with a solid-state relay to realize PID heating control, ensuring the temperature rises uniformly to 750 +/- 1 degrees C, and the time from room temperature to 750 degrees C is less than or equal to 45 minutes.
• Maximum relative average temperature deviation: less than or equal to 10 degrees C within 10 minutes.
• Three built-in programs are provided: new furnace heating, calibration heating, and normal test heating.
• An embedded integrated 7-inch touch screen enables control parameter setting and display, experimental data acquisition and storage, screen monitoring, real-time temperature curve display, and historical curve and data query.
• The system has audible alarm and alarm event display functions.
• Test reports and test curves can be printed freely without an additional printer.
