Understanding the Comparator Reticles

Thanks to these inserts, you can check thickness fast—without guesswork or delay.
Onsite Use of the Spray Foam Pocket Comparator
In the field, simplicity and speed matter. That’s why this pocket comparator works so well. It fits in your pocket, and the 6x magnifier helps you see every detail. Because there are no batteries or settings to manage, you can focus on the job. Also, it works well in heat, cold, or humidity.
Why It’s a Smarter Choice Than Digital Gauges
Digital gauges can be helpful, but they aren’t always practical. For example, they often need charging or calibration. They may not hold up to harsh conditions, either. In contrast, the Spray Foam Pocket Comparator is simple, fast, and tough. That means fewer delays and more confidence in your results.
