Awesome

This analyzer is a beast. The layout is super modern , like some certain other companies that are names after fruit... Great readings, tons of features and the touchscreen/graphical display with onsite printing is a big draw for customers. The modern tools really make a big impression on the less technical folks you do work for. And it's super convenient.

Industrial Analyzer

Due to its size it may seem intimidating to pick up and use, but it is rather fairly simple and easy to use. The analyzer provides the user with loads of information and has a bright colorful display with easy to read font.

Rugged

This thing is like a computer, so I was worried about it being fragile. It wasn't. Wohler made the A 550 for the job site. They knew how we'd all end up using it. It's accurate and easy to navigate.

Detailed display

Large touchscreen color display and several measurements being on one screen at the same time allow for detailed analysis of applications. The A550 is a industrial analyzer capable of measuring higher ranges of gases compared to other analyzers. It does have a bulky tablet design however, its capabilities justify it because this will probably be the only device you need to carry around.
