Where It Fits

Quantify Leaks Anywhere

Available in C1D2 and ATEX Zone 2 configurations, the high-volume sampling system is built for field gas collection points where emissions measurement must be accurate, repeatable, and compliant with site safety standards.
Pipeline Leaks and Valve Checks

Capture fugitive releases or controlled venting to quantify methane emissions and confirm repair success.

Compressor Rod Packing Vents

Measure leakage rates and evaluate seal integrity under normal operating loads.

Tank Thief Hatches and Relief Devices

Sample emissions from storage and transfer operations for material balance and reporting.

How it Works

Use an optical gas imaging camera (OGI) or another device to find the leak.

2

Setup
Connect probe/sample line, leak check, zero verification.

3

Start Sampling
Use desired fan setting and start sampling leak rates, with real-time data visualization.

The Results

Powerful, Transparent Reporting

All sampling data is stored in a secure, queryable SQL database that gives users instant access to records, run histories, and audit trails. Default report templates summarize sample runs, flow totals, and QA/QC checks, while advanced users can build fully customized reports to match internal or regulatory requirements.

The result: fast, defensible documentation—ready for analysis, compliance, or stakeholder review.
