Product Review: KNICK Stratos Pro
If you want versatility, then consider a multi-parameter device. It can measure several process variables or provide an installation base for the same type of device, giving your maintenance crew a break. Some even have more than one input, although maybe you’re fine with skipping the extra channels.
Today, we have a new company on Visaya! It’s nice to have more brands here, right? The gang from KNICK gets its groove on with liquid analysis and has brought the Stratos Pro to Visaya. Let’s discuss the features and how you can fit this device into your application.
Grab your sunglasses (it’s sunny today), have a read, and draw your conclusions!

Whatcha got there?
Let’s discuss the most relevant part of the device, the design! Without a good design, your process can’t run correctly, right? Yes, I’m kidding, but you know I like to discuss the design. 😉
The Stratos Pro resembles its competitors in both shape and size, 148 x 148 x 117 millimeters and around 1.2 kilograms, so nothing special there. The display is a bit smaller than usual, but it comes with a feature that helps make up for that. We’ll talk about that in a sec.
It also has a local keypad to set up the device without a handheld, which I always appreciate. The keypad itself has a good design, with arrows and a multi-function button in the middle, then a button on each side for measurement values and more information. It also has connections for setting up two digital sensors, two current outputs, and one analog input. Not bad at all!
What can it do?
The Stratos Pro can measure several process variables such as pH/oxidation-reduction potential (ORP), conductivity, and oxygen. Depending on the industry segment you work in, you may need approvals, enclosure protection, and so on. For hazardous areas, you can apply this device up to Zone 1 with no issues. The IP67 enclosure is UV-resistant as well. Sounds nice, huh?
You can get seamless integration if you have analog, HART, FOUNDATION Fieldbus, or PROFIBUS PA. If you want Ethernet, move up to the next level of devices, because you won’t find it here. The provided protocols will cover most applications, but KNICK should consider expanding to stay competitive.
Why should I care?
I gotta tell ya, I’ve had trouble finding reasons for you to care about several devices in past reviews. However, the Stratos Pro has good features to consider for your next project.
The number of input options and process variables alone make it worth talking about, but it’s simple to set up too. It has intuitive navigation through the menu, saving you time when you need to check data or set up a new function.
Like other options on the market, you can have digital or analog sensors. The Stratos Pro uses the open technology called Memosens, so you can buy your sensor(s) from plenty of vendors rather than being stuck with one.
It even has a few fancy features, nice on a basic device. The wireless service port means you don’t need to open the transmitter to set up. Great feature! Too bad I couldn’t find much information on it. If you know more about it, drop me a comment and let me know.
Last but not least, the display has a color-coded user interface, where the screen changes color according to the condition of the device. For example, in standard measuring mode it stays white, but an alarm or error message makes it go red. You have six colors, so this feature will get your attention in the field – and maybe during the holidays as well.
The KNICK Stratos Pro offers some impressive bells and whistles for a lower-tier device. You might do well to scale this one out for your process, so plug in your numbers and see!
