GasFinder2-MC: Multi-Channel TDL Analyzer

Measurement Heads/Probes

  • Open Path Head


    The OP3 transceiver head is our largest open path transceiver which is mounted on a precision two-axis X-Y mount and housed in an enclosure (stainless steel or plastic) for weatherproofing if required. The OP3 has an integral telescopic sight and visible laser connection to aid alignment over longer paths up to 750m.


    Weight: 5 kg [11 lbs]

    Size(LxWxH): 350 x 100 x 200mm

    [13.8 x 3.9 x 7.9 inches]

    Power not required.

  • Stack and Duct Probe


    The Stack/Duct probe enables in-situ gas measurements with a transceiver module mounted on one side of a duct and a reflector module mounted on the other side. Laser light directed from the transceiver across the duct to the reflector and back measures the average concentration of target gas in the duct. The transceiver is supplied with adjustment screws and a visible laser connector to make alignment easy and secure. The probe does not require local electrical power. Compressed air supply is recommended to keep optical surfaces clean. Typically no heating or cooling is required.


    Weight: 4.5 kg [9.9 lbs]

    Size (Lxdia): 300mm x 160mm. [11.8 x 6.3 inches]

    Power not required.

  • Extractive Gas Cell (EGC)


    The Extractive Gas Cell (EGC) allows for real-time flow through measurements to be accurately quantified. The EGC is configured with a transmitter and receiver mounted on either side of the active measurement area. The inlet and outlet connections are faceted with standard compression fittings to allow for ease of compatibility. The diameter and length of the measurement path is able to be customized to meet the specific requirements of your application. The EGC has no moving parts and does not require any power. If hearing heating is required then the optional heating and insulating package is available.


  • Insertible Probe



    The In-Situ Probe utilizes the transceiver head configuration to keep all of the active measurement components out of the active measurement area. This is ideal for stack and duct monitoring applications where there is only one flange connection available.
