Product Description

Product introduction
This Concentration Limits Testing Equipment is applicable to the determination of upper limit and lower limit concentration of combustible mixture formed by chemical substance vapor and air under test temperature and normal pressure. Inert gas can be used as diluent in the test, but substances with stronger oxidizability than air cannot be used.


Standard
ASTM E681 Standard Test Method for Concentration Limits of Flammability of Chemicals (Vapors and Gases).

Main features:
1) This Flammability of Chemicals Testing Equipment is embedded processor, Windows CE operating system
2) 8-inch LCD touch screen, which can display the test status in real time
3) Optional 5L and 12L round glass test containers, with full gas mixing and good compatibility
4) This Concentration Limits Testing Equipment is equipped with explosive pressure relief device (pressure relief door and spring compression device)
5) Integrated heating and cooling design, compact instrument structure
6) Built in air circulation system to ensure the uniformity and stability of box temperature
7) The pressure sensor and thermocouple are combined to detect the sample status. The equipment also automatically monitors and records the test ambient temperature, humidity and atmospheric pressure
8) This Flammability of Chemicals Testing Equipment is equipped with high-precision pressure sensor to accurately control the concentration of gas partial pressure
9) Magnetic stirring, remote start control, automatic ignition control, precise ignition time
10) Automatically clean the container sample and combustion products by extracting internal gas
11) Supplied with a bottle brush, and use fine sand+detergent and clean water to clean the substances adhered to the bottle wall
12) Double layer tempered glass observation window protection door and back pressure relief door with anti fog are adopted, which are safe, reliable and convenient for observation
13) Double interlock protection, when the door is not closed or the temperature does not reach the target temperature, the ignition operation is invalid
14) Configure a video monitoring system to record the test process. After the test, observe and judge the final result through playback
15) The test process is fully automated, supporting parameter setting, data storage, report viewing and other functions
