HJ/T 47-1999 "Technical Conditions for Smoke Samplers"

2、 Product Introduction

This sampling tube can filter, heat up, and rapidly condense and dehydrate pollution source exhaust gases, reducing the impact of moisture and particulate matter on flue gas detection results; Small in size, light in weight, easy to operate, and widely used, especially suitable for portable sampling and analysis of flue gas under high humidity.

3、 Performance characteristics

◆Adopting a miniature high thermal conductivity condensing device with a built-in steam water separator, it has fast cooling speed and high condensing efficiency.

◆The heating tube heats up quickly, evenly, and efficiently, with a low surface temperature of the gun body and no burning sensation.

◆The front end is a PTFE sampling tube and the inner surface of the condensing device is sprayed with PTFE coating, which has a small gas adsorption effect and is less likely to leave water droplets.

◆The peristaltic pump automatically drains water, which is convenient and practical.

◆Using double-layer semiconductor refrigeration chips for cooling, the cooling temperature difference is large, and it is not affected by vibration or turbulence, making it stable and reliable.

◆Vacuum titanium plating treatment on the surface of 304 stainless steel can effectively prevent corrosion of the gun body in high temperature and high humidity environments.

◆Configure extendable sampling tubes to meet more sampling needs.

◆The replaceable membrane filter effectively reduces the pollution of particulate matter in the flue gas to the flue gas analyzer.

◆Built in cooling fan, heat sink, and semiconductor refrigeration chip can prevent foreign objects from falling into and damaging the fan.

◆Adopting low-voltage 12V DC power supply to eliminate safety hazards.

◆Ultra low power consumption, dual-use for both AC and DC.

◆Small size, light weight, easy to carry, convenient platform for sampling smoke.
