Retro 1CC for 100m

      Retroreflector 500m

Measurement Principle:

Boreal Laser’s GasFinder2F (US Patent 5,637,872) Open-Path Monitor measures gas concentration over an open path and consists of an integrated transmitter/receiver unit and a remote, passive retro-reflector array. The remote retro-reflector is targeted by the operator using a two axis instrument mount and an on-board visible aiming laser.

The transceiver houses the laser diode source, drive electronics, detector module and microcomputer subsystems. The transceiver unit is contained in a weatherproof enclosure and has connectors for power input and data I/O.

Patented features:

 

Provide laser gas detector leadership in price, performance, and ease of use.

·          “No phase adjustment” detection technology:

      Enables open paths from 1m to 1000m without requiring any phase adjustments or calibration.

·          Built-in, permanent calibration reference cell:

GasFinders are delivered calibrated and they are self-calibrating .

A schematic representation of the GasFinder system is shown below.

The laser light emitted from the transceiver unit propagates through the atmosphere to the retro-reflector and returns to the instrument. A internal mirror focuses the optical signal onto a photodiode detector. Simultaneously, a portion of the laser beam is passed through an onboard reference cell to provide a continuous calibration update. These two optical signals are converted into electrical waveforms which the micro-controller processes to determine the actual concentration of gas along the optical path. The computed gas concentration is then displayed on the back panel of the instrument as well as being transmitted to the customer’s central computer where the data may be collected, stored, and displayed.
