ZR-D07A Asphalt Fume Sampling Tube
Product Introduction
ZR-D07A Asphalt Fume Sampling Tube is a professional sampling accessory designed for the collection and measurement of asphalt fumes from fixed pollution sources. It is mainly used in environmental monitoring, occupational health, industrial safety inspection, scientific research, and laboratory analysis.
The sampling tube adopts the gravimetric measurement method specified in HJ/T 45-1999 "Determination of Asphalt Fume in Exhaust Gas from Stationary Sources – Gravimetric Method". During sampling, asphalt fumes are collected by a pre-weighed glass fiber filter cartridge. After removing moisture, the asphalt fume concentration is calculated based on the mass increase of the filter cartridge before and after sampling.
With a safe low-voltage heating design, stainless steel structure, and convenient cooling system, the ZR-D07A provides reliable sampling performance for fixed pollution source emission monitoring.

Performance Features
• Designed according to HJ/T 45-1999 standard
The sampling tube meets the technical requirements of the national standard method for asphalt fume determination from fixed pollution sources.
• Safe DC12V heating power supply
The heating and constant-temperature system uses a DC12V safety power supply, providing electrical isolation from mains power and improving operator safety.
• Stable temperature control performance
The heating system maintains suitable sampling conditions to ensure efficient collection of asphalt fumes.
• Ice cooling system design
The cooling system adopts an ice cooling method, which is simple to operate and convenient for field sampling.
• Stainless steel construction
The metal components are made of corrosion-resistant stainless steel, ensuring durability and suitability for industrial environments.
• Lightweight and portable design
The compact structure makes it easy to transport and operate during on-site environmental monitoring.

Working Principle
The ZR-D07A Asphalt Fume Sampling Tube works based on the gravimetric sampling method.
During sampling, exhaust gas containing asphalt fumes enters the sampling tube. Asphalt particles and condensed fume components are collected by a pre-weighed glass fiber filter cartridge. After sampling, the filter cartridge is dried to remove moisture and weighed again.
The difference between the filter cartridge mass before and after sampling represents the collected asphalt fume mass. Combined with the sampled gas volume, the asphalt fume concentration in the emission source can be calculated.
