CO% Range Gas Analyzer: GPro 500
Tunable Diode Laser for CO% Measurement
The GPro 500 carbon monoxide percent gas analyzer is a unique tunable diode laser spectrometer designed for measurement of CO in a gas stream at high temperatures. It uses a folded-path laser beam design for simple installation and CO% measurement.
Top Performance in CO% Measurement
A CO% analyzer for challenging applications, the GPro 500 provides reliable measurement in FCC units, PTA, steam reforming, and hydrogen production.
Low Maintenance and Operating Costs
This CO% gas analyzer is designed to operate at high temperatures, in situ without a conditioning system, reducing the total cost of ownership.
The GPro 500 is an alignment-free TDL gas analyzer, meaning that the typical challenges of TDL installation and alignment are significantly reduced.
TDLCO Gas Analyzer Frequently Asked Questions
Why use a TDL sensor for measuring carbon monoxide?
TDLs have many advantages over other carbon monoxide measurement technologies. Firstly, they are installed in situ in the process pipe or vessel so are exposed directly to the gas and therefore measure immediately. Some other analyzers measure a sample of gas that has been extracted and conditioned, which takes time and increases risk. Secondly, TDLs are immune to the presence of other gases in the process and will only measure CO. Thirdly, they are extremely reliable and require practically zero maintenance.
How can a CO TDL reduce costs?
Unlike other gas measurement technologies, TDLs have a very low maintenance requirement. Once installed, they will run reliably for many months without needing any maintenance. When used in combustion processes they can ensure the fuel/air mixture is exactly right and can reduce fuel costs by thousands of dollars. For more information check our Payback Calculator.
Are TDLCO sensors easy to install?
Sometimes. Once the insertion point has been selected it’s a matter of fitting one or two flanges and a temperature and pressure sensor. Most TDLs are of a cross-stack design, meaning that they’re comprised of two parts (laser source and receiver) that sit opposite each other in the pipe or vessel. The two units have to be very carefully aligned which can be problematic. The GPro 500 has both parts installed in the same unit. The laser source is reflected by a three-sided mirror and is directed back to the receiver. Therefore, no alignment is required. Watch our video on easy installation.
In which applications can TDLs be used?
TDLs have a wide range of applications, including process control in direct chlorination and oxy-chlorination; safety monitoring in VCM waste gas recovery; and combustion optimization in package boilers, thermal oxidizers, fired heaters, FCC units, etc. For more information check our Application eBooklet
