Product Detail
Vacuum bag sampler provides fast sampling with zero cross-contamination. The sampler allows sample bags to be filled directly by using negative pressure. It can be used to collect volatile organic compounds (VOCs) and other gaseous samples from fixed pollution sources and ambient air.
We have two models:
ZR-3520 Vacuum bag sampler(for fixed pollution sources and ambient air)
ZR-3730 Vacuum bag sampler(for fixed pollution sources only)
Applications
> Industrial VOCs
> Indoor air quality
> Effluent gas samples
> Stack sampling
> Ventilation studies
> Hazardous Material (HazMat) testing
Standards
HJ 604-2017 Ambient air - Determination of total hydrocarbons, total methane and non-methane hydrocarbons - Direct injection / gas chromatography
HJ 732-2014 Emission from stationary sources-Sampling of volatile organic compounds-Bags method
HJ 38-2017 Stationary source emission―Determination of total hydrocarbons,methane and nonmethane hydrocarbons―Gas chromatography
GB 13223-2011 Emission standard of air pollutants for thermal power plants
Features
> One button operation. Cleaning and replacement automatically, no need to plug or unplug the bag.
> Built-in battery≥12H.
> Protects sample pump from contamination
• Sample does not pass through the pump
• Sample contacts only inert tubing and bag. Ensure that the collected samples are free from contamination and adsorption.
> Rugged heavy-duty, airtight construction.
