Buyer's Guide

Why choose this model?

The Model 90 CA is the most cost-effective product we offer for measuring static contact angle. With lightweight construction and a small footprint, the Model 90 CA is easy to set up and transport. The user-friendly DROPimage CA software makes contact angle measurements fast and simple.

Suggested alternatives

If you need to measure surface energy but still want the Model 90 bench, consider the Model 90 Pro. For a more durable bench construction with easier repositioning and options to upgrade the instrument with accessories and more advanced capabilities, consider the Model 190. If you need to study wetting and perform dynamic contact angle measurements, consider an instrument with DROPimage Advanced, such as the Model 250.

All ramé-hart systems are supplied as fully functional turn-key systems, with a PC, pre-installed and configured software, and the components and tools needed to set up and operate the instrument. Compatible accessories and software upgrades can be added later as your needs grow.
