Vacuum Box Sampler
MH3051 vacuum box sampler using negative-pressure intake principle for gas bag VOC sampling and field monitoring.
Vacuum Box Sampler for environmental monitoring projects
MH3051 vacuum box sampler for vacuum-assisted gas bag sampling of fixed pollution source VOC emissions and negative-pressure flue gas sampling scenarios.
MH3051 is a vacuum box sampler using negative-pressure intake. It is intended for fixed pollution source VOC emission sampling and monitoring, research institute sampling analysis and other gas bag sampling occasions, especially negative-pressure flue gas scenarios.
The product supports vacuum box pressure range from -13 kPa to +5 kPa. The sampling interface supports gas bag volume settings, with examples of 1 L and 3 L gas bag timing. It references HJ732-2014 for fixed pollution source waste gas VOC bag sampling.

| Item | Specification / selection note |
|---|---|
| Product direction | Vacuum box sampler for VOC canister sampling support |
| Sampling context | Ambient or source VOC sample collection where canister filling method is required |
| Selection basis | Canister specification, target compounds, sampling flow and field method |
| Connected products | VOC sampler, gas chromatograph and GC-MS laboratory analysis |
Configured around the actual monitoring point
Sampling method, container, flow stability and preservation condition determine the equipment package.
Flue gas, VOC, ambient air or field sampling media
Temperature, moisture, dust, solids, corrosive components or compound type may affect configuration.
Analyzer, detector, sampler, cabinet, pretreatment and data output can be combined as one product package.
Specifications are prepared according to the selected model and actual project requirement.
Details Huisheng reviews before confirming a model
Huisheng reviews the product model together with the measured medium, target range, sampling condition, installation position and required specifications. This keeps the product discussion tied to the real monitoring point.
Canister, adsorption tube, stack gas, particulate or other field sampling methods are matched with the application.
Sampling flow, duration, volume and stability are matched with the required procedure.
Canister, adsorption tube, filter holder, absorption bottle or sample container requirements are matched with the sampling method.
Field sampling setup with pump, line, container, flow control or tripod/enclosure
Sampling record, storage condition and laboratory follow-up requirements are included in the discussion.
Monitoring indicators covered by this product series
The final parameter package depends on the selected model, measuring range, sample condition and data output requirement. For many projects, one instrument is part of a complete monitoring point rather than a stand-alone purchase.
