Execution standards：

GB/T 3836.18-2017 "Explosive Atmosphere Part 18: Intrinsically Safe Electrical Systems"

GB/T20964-2007 "Dust Sampler"

scope of application：

This instrument is an ideal tool for air detection and sampling in workplaces with harmful, toxic, and explosive gases at all levels of health and epidemic prevention systems, disease prevention and control centers, schools, research institutions, and industrial and mining enterprises. It is particularly suitable for sampling toxic gases and dust underground in coal mines.

Instrument composition：

The sampler consists of an imported vacuum pump, a microcomputer controller, a multifunctional LCD display and charging voltage protection circuit, a lithium battery pack, and a digital flowmeter. The casing of the sampler is made of high-quality ABS plastic material, which has flame retardant, moisture-proof, and anti-static properties.

main features：

1. The working process of the sampler is fully controlled by a microcomputer, which is reliable, easy to operate, and highly intelligent;

2. The sampler adopts a digital flowmeter, which can measure the flow rate in real time. It adopts advanced pulse width speed control, and the flow rate can be continuously and automatically adjusted with good dynamic characteristics;

3. The sampler adopts an imported vacuum film pump, which has small volume, low heat generation during long-term operation, low power consumption, high vacuum degree, low noise, long service life, and reliable operation;

4. The machine uses a mining lithium battery pack with a large capacity (4000mAH), no battery memory effect, long lifespan, and uses a dedicated charger for good charging effect;

5. In the lithium battery pack of the sampler for mining, a short-circuit current limiting protection device is specially designed to ensure that the sampler operates within the intrinsic safety current range, thereby improving the explosion-proof performance of the sampler;

6. Segmented LCD Chinese display, intuitive and convenient, zero power consumption;

7. Blue backlight, suitable for display under various lighting conditions;

8. Has coal safety explosion-proof certification.
