Standards
ASTM E2019:Standard Test Method for Minimum Ignition Temperature of Dust Layers
IEC 61241-2-3:Electrical Apparatus for Use in Explosive Dust Atmospheres - Part 2-3: Test Methods - Determination of Minimum Ignition Temperature of Dust Layers
ISO/IEC 80079-20-2:Explosive Atmospheres - Part 20-2: Equipment Protection Levels (EPL) - Classification of Equipment for Dust Atmospheres
GB/T 16428:Test Method for Explosion Limits of Dust Clouds
Features
1. It has built - in commonly used international test standards, allowing for testing according to standard parameters or custom - setting.
2. During testing, only the ignition energy value needs to be input, and the instrument automatically selects the optimal combination of capacitance and voltage.
3. The high - voltage charging module automatically disconnects, improving operational safety.
4. The powder dispersion device is reasonably designed to ensure uniform dispersion of powder samples.
5. The instrument is flexible to use, with easy adjustment of the electrode spacing, spraying pressure, and delay time.
6. It automatically records the number of times the electrode ignites and reminds users to replace the electrodes in a timely manner to prevent electrode wear from affecting the test results.
7. The Hartmann tube is equipped with a lifting and rotating mechanism, which is convenient for cleaning and saves experimental time.
8. Remote ignition ensures the safety of experimenters.
9. User - level management enables the management and control of accounts at different levels.
10. The USB interface is plug - and - play, facilitating data management.
11. With professional industrial design, it is simple and elegant.
12. It has a user - friendly human - machine interaction, making it easy to learn, understand, and operate.
13. It is equipped with a 7 - inch color liquid - crystal touch screen that dynamically displays the experimental progress.
