Gas Analyzers

What are Gas Analyzers?

Gas AnalyzerReal-time gas analysis enhances efficiency, safety, throughput, product quality, and ensures environmental compliance. Gas analysis can utilize various technologies such as tunable diode laser spectroscopy, zirconia oxygen analysis, infrared gas analysis, stack gas analysis, dust monitoring, process gas chromatography, continuous emissions monitoring systems (CEMS), hydrogen purity analysis, and gas density systems. Selecting the correct technology is critical to measurement accuracy, reliability, and durability.

Yokogawa's years of application expertise enable our customers to save time, money, and resources by collaboratively selecting the optimal gas analyzer solution.

Edition 1
Overview:

The EPA rule, 40 CFR 63 Subparts CC and UUU, is forcing refineries to monitor flares. Fortunately, modern analyzer technology makes it possible to meet the requirements, generate the necessary reports, and stay in compliance.
Here’s how to select the right analyzer to meet these demands.

AV8C Channel reset code
(KB-000-0410)
You can use code 58 to reset a single AV8C channel.  First scroll the display to the channel you would like to cycle, then enter code 58. 
Here's a link to download the AV8G Manual. 
The part number you see on the channel card circuit board is not the part number for the channel card. It is the part number for the circuit board before any parts are installed.  There are 2 versions on the channel card.  If you look at ...
The AV550 automatically turns off the power to the channel card when it is removed. You have to either cycle power to the whole unit, or use the channel card power.  To get to the channel card power menu hit the Setup Key (wrench). See below:&n...

Overview:

Yokogawa’s new TDLS8000 houses all of the industry’s leading features in one robust device. The platform design is for in situ measurements which negate the need for sample extraction and conditioning. The non-contacting sensor allows for a variety of process types including corrosive, abrasive and condensing. The first generation platform has been proven in many others for the measurements of O2, CO, CH4, NH3, H2O and many more NIR absorbing gases. This second generation platform has improved reliability and ease of installation and maintenance while still meeting or exceeding designed application demands.
