Remote Point (RPX) Probe Assembly

For the GasFinder3-DC (DUAL CHANNEL)


The GasFinder3-DC and the associated Measurement Heads are a field deployable Open-Path Tunable Diode Laser (OP-TDL) based gas analyzer system that is primarily used for:

  • Leak Detection – provides immediate and unambiguous detection of fugitive gas releases in industrial safety applications
  • Ambient Monitoring – Continuously monitors gas concentrations over open area and/or point sources for environmental monitoring applications

This technology is also most commonly referred to as Open Path Gas Detection (OPGD) or Line of Sight (LOS).

This particular technology is ideal for detecting or monitoring for a number of different Toxic, Combustible, Hazardous, or Greenhouse Gases.

Core System Components

GasFinder3-DC: is the analyzer or also known as a CCU or Controller. The GasFinder3-DC houses the laser and electronics.

Measurement Head(s): attachment used to form the Active Measurement Path and provides the direct sample for the GasFinder3-DC to analyze. There are three core Measurement Heads available for the GasFinder3-DC – Open Path (OPX) Head, Remote Point (RPX) Probe, and the Stack/Duct (SDX) Probe.

Accessories: additional components used to provide additional functionality or increase ease of use for the end-user.


Use Applications:

Early warning for the release of the toxic Hydrogen Fluoride is critical. The wide area coverage, one second response time, and very low detection limits make Open Path Laser Gas Detection ideal.
