GASFINDER2-MC: MULTI-CHANNEL TDL ANALYZER
THE MOST COST EFFECTIVE MULTI-PATH GAS ANALYZER ON THE MARKET
The Multi Channel Analyzer is a rack mountable, fibre-coupled monitoring system that can make up to eight measurements simultaneously in a variety of safety, environmental, and process monitoring applications.
What It Does
- Provides immediate and unambiguous detection of the target gas in the ambient atmosphere
- Our technology counts every target molecule in the measurement path to give a ppm-m concentration
How It Works
- The analyzer is housed inside a climate controlled and non-hazardous building
- Fibre optic cable carries the laser light from the analyzer to the remotely mounted measurement heads
- The laser passes across the active measurement path
- The laser light is then collected and the signal is carried back to the analyzer via coaxial cable
- The ppm concentration is then transfer to the communication module(s)
Benefits
- No interference with other gases
- No memory effects
- Data collection and interpretation is simple and intuitive
- Built for winter and summer
- Minimal Maintenance
- Sophisticated self-diagnostics
- Can provide an independent sample or reading every second
- Free and unlimited phone and email support
Multi - Channel System Description
Boreal Laser’s patented (US Patent 5,637,872) TDL (Tunable Diode Laser) fibre coupled monitor measures gas concentration over an open path. The monitoring system consists of a rack mounted integrated transmitter/receiver known as the Central Control Unit (CCU), an open path transceiver head or duct probe, and a remote, passive retroreflector array.
The laser signal from the Multi-Channel System is sent through a fibre optic cable to the remote head or duct probe where it is emitted and propagates through the atmosphere to the retroreflector. It then returns to the cell where it is focused on to a photo diode detector. The detector converts it to an electrical signal which travels through a coaxial cable to the electronics in the Multi-Channel System.
A portion of the laser beam is passed through an on board reference cell to provide a continuous calibration check. These two optical signals are converted into electrical waveforms which the computer processes to determine the actual concentration of gas along the optical path. The computed gas concentration is then displayed on the rear panel of the instrument, and can be transmitted to a computer where the data can be collected, stored, and graphically displayed.
For industrial applications a 4-20mA, serial, MODBUS, TCP/IP, and dry-contact relay outputs are also available.
A software program, GasViewOP is available which runs on the computer and can be used to alter some of the parameters on the Multi-Channel System.
