Double-control + automatic proofing building materials non-combustible test furnace
Scope of application
The test furnace is developed according to the technical indicators and requirements specified in the national standard GB/T5464-2010, and is applicable to the specified test method for evaluating the combustion performance of building materials under laboratory conditions.Suitable for testing the combustion performance grade of Class A fire proof materials in GB8624 combustion performance grade of building materials.
Product function characteristics
1. Dual control mode: can be controlled on the touch screen, or on the computer, operation mode can easily switch; a device can be operated at the same time, several computers can be online at the same time, can achieve LAN sharing; (users own computer, printer; upper computer software, router, network cable we will issue with the equipment)
2.With the automatic sample release function, the sample can be automatically put into the furnace after the temperature is stable. The sample basket can automatically rotate 90 degrees after the outlet of the sample, and the sample is replaced.The automatic sample setting process can be suspended at any time, and the small sample basket can automatically return to the initial position;
3.Microcomputer technology and silicon controllable technology are used to adjust the furnace body temperature through powe
4. High degree of automation, show and record the surface temperature of the furnace, sample center and sample during the test, and the test steps will automatically jump out of the operation prompt.
5. The historical curve can be queried to automatically judge the temperature balance.
6. The test process is safe and reliable and convenient for operation.
7. Custom version of the mold forming refractory furnace, good heat insulation performance
8. Using high-quality bar heaters, the furnace temperatures can rise to 900℃.
9. LC+NAbview professional software displays the in-furnace temperature, sample center temperature and sample surface temperature curve in real time, which can realize automatic control, data collection and processing, data preservation and output measurement results.
10. The top is equipped with an observation mirror to facilitate the user to observe the combustion state of the sample in the furnace.
11. Resettlement thermocouple, sample center thermocouple, sample surface thermocouple in the furnace;
12. Thermocouple scanner with 360 degrees rotating and lifting；
13. Stainless steel inverted conical air stabilizer and cylinder guide shield；
14. The e software automatically controls the heating rate and controls the furnace body temperature in stages；
15. In the software, the current regression judgment temperature balance conditions are included
