amazing display
Wohler definitely brought their A Game with this new Analyzer. Very huge touchscreen display. The probe connection is hidden even when you snap it together to offer added protection. Very high accuracies as well. great great analyzer.

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.

Well thought out analyzer
This Wohler analyzer is a class unto itself. It may not be for the average HVAC technician, but for those who own it, they will be happy as well as their customers that they made the investment. It is a well thought out analyzer that makes my job so much easier.

Beast of a meter
Yes, it’s expensive. that’s probably what most people notice at first but two things to consider. One: you gotta spend money to make money. Cliche but true, I always think of it as investing in my business and I can tell you when you show up with this space age looking thing, customers respect it. Obviously it needs to be a good meter that takes accurate readings (and it DEFINITELY is) but we shouldn’t discount the wow factor. Stuff is a lot image these days. and Two: It’s actually quite a reasonable price when you look at the sensor configuration. A comparable analyzer from another brand is going to cost you somewhere around here anyway and they are usually more old fashioned than this and lack much of the convenience that comes with the software in this one. This is my long way of saying that if you’re willing to spend the money, you won’t be disappointed with this thing. Highly recommended for those that care about staying on top of the game with their equipment.

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.

top of the line
From what I understand Wohler is one of, if not the, leader’s in the european combustion market and it’s easy to see why when you get ahold of this thing. It performs to the highest standard but you sort of “know” when you turn it on that it’s going to be powerful. The feel of it and the diversity of testing options is intense and it basically does everything you need for complete combustion analysis, including measuring a lot of gasses that you wouldn’t pay attention to in the residential jobs. I think it’s worth the money and I love it for my work, but obviously take your budget into consideration. It’s a big investment but worth it.

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.

Not that complicated
I thought this unit was going to be a bear to use, I've been used to my old unit for years. The A 550, though was not as complex as I feared. I was up and running pretty quickly.
