Find Your Optimal Solution
Selecting the right module architecture is the most important decision for your project's success. Compare our two purpose-built solutions to find the perfect fit for your gas path, process conditions, and integration requirements.
In-pipe measurement
Engineered for high-concentration CH₄ measurement in coal-mine gas-drainage pipelines. Eliminate sampling delays and reduce system complexity with direct in-pipe measurement.

Extractive measurement
Upgrade your host analyser with a high-performance TDLAS core. Ideal for applications requiring conditioned sample delivery across four standard gas directions.

Explore Extractive Module →Side-by-Side Comparison
| Decision | Pipeline insertion module | Box-level extractive module |
|---|---|---|
| Measurement position | Optical window inside the process pipeline | Optical measurement inside the host analyser |
| Gas transport | Process gas flows through the insertion window | External pump and conditioning path deliver the sample |
| Main current gas | CH₄ | CH₄, CO₂, CO and NH₃ standard directions |
| Pressure question | Pipeline absolute pressure and compensation validity | Pressure and flow at the module after conditioning |
| Response question | Gas movement through the in-pipe window plus algorithm | Transport lag + cell exchange + analyser response |
| Host responsibility | Display, interlock logic, enclosure, approval and field wiring | Pump, filters, moisture handling, display, alarm and enclosure |
| Do not choose when | Direct insertion is prohibited, unmaintainable or unrepresentative | Sample transport or gas conditioning changes the measurand beyond control |
Expert Engineering Guidance
Check process fitting, insertion clearance, maintenance isolation, representative flow and any hazardous-area responsibility.
Review sampling forms →Record normal, minimum and maximum absolute pressure, plus the expected rate of change.
Build the pressure envelope →State whether the value informs display, trending, alarm, process control or a protective interlock.
