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)

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.

OP3 Transceiver

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.

Specifications:
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/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.

Specifications:
Weight: 4.5 kg [9.9 lbs]
Size (Lxdia): 300mm x 160mm. [11.8 x 6.3 inches]
Power not required.
