Boreal - Extractive Measurement (EMX) Cell Assembly
Analyze an Extractive Sample: Ideal for difficult for challenging applications. Use in Hazardous Area Applications: (A) Ex ib IIC T5 Tamb less than 70°C Gb (C1 Div1, G: A, B, C, D) . No Calibration + No Intervention: Due to the GasFinder`s Internal Reference Cell. Remote Measurement Head: Paired with one of our GasFinder3 Instruments. When combined with one of the GasFinder3 Analyzers, it creates a direct and non-contact extractive measurement for quantitative or feedback control applications.

Use in Hazardous Area Applications
(A) Ex ib IIC T5 Tamb <70°C Gb (C1 Div1, G: A, B, C, D)
Laser Light is the Sensing Element
Class 1 Eye Safe: Near Infrared (NIR) laser light
This Counts the Target Gas Molecules
As they pass through the Active Measurement Path
Quantifiable Volumetric Result
Confirmation of both gas type and concentration
No Interference + No False Alarms
This only detects the specific target gas of interest
Form the Active Measurement Path
With the Open Path (OPX) Head + Retro-Reflector
Easily Obtain + Maintain Alignment
Align with one hand without needing hand tools
Superior Tolerance to Vibration
Vibration helps to integrate and quiet the analysis
High Laser Power + Tight Collimation
Optimized for use in short/long path applications
Understanding the Components
To best understand if this Measurement Head is ideal for your application, it vital to understand what is included.

The Extractive Measurement (EMX) Cell Assembly has the following configurable options:
- Process Pressure: There is a spectroscopic limitation on pressure to 100 kpag (15 psig).
- Process Temperature: There is a spectroscopic limitation on temperature to 150C (300F).
- Other Process Conditions: In general, the gas following through the Extractive Measurement (EMX) Cell should be both clean and dry as to not foul the windows.
- Material of Construction: The Wetted Process material can either be Stainless Steel of Hastelloy.
- Path Length Options: The 1″ NPT Wetted Process Pipe is available in lengths of: 1m, 0.5m or No Pipe included.
