Discover the Power of Tri-Color: The New Standard in Containment Testing

Did you know laser visualization of airflow isn’t new? The revolutionary concept was pioneered by Dr. Rong Fung Huang (黃榮芳), PhD, from the National Taiwan University of Science and Technology in Taipei. Back in 1991, his dramatic results with lasers led to a breakthrough hood design, later granted U.S. Patent No. 7,318,77. This innovative design utilized an air curtain to convert traditional 3D airflow to a 2D plane, significantly reducing turbulence. Dr. Huang's continued use of laser visualization has resulted in several groundbreaking hood patents, crediting the technique for his pioneering insights.

In 2007, Dr. Huang introduced me to this transformative technique. I used it to develop the Collegedale G3 hood and became a firm believer in the power of lasers. However, the equipment was costly, difficult to set up and required eye protection, making it suitable only for research and R&D labs.

What if we could bring this technology into the field? With Dr. Huang's help, I developed a handheld line laser by converting a green laser pointer with a beam splitter. This was a step forward, but still too complex for practical, everyday use. It took me years of practice to be able to demonstrate the things I wanted others to see.

The pandemic gave me time to work on my passion projects, including making laser visualization accessible to all fume hood users. Thus, the Tri-Color project was born. With the help of my four partners, we aimed to simplify the process so much that even a fifth grader could use it. This led to the creation of today's Tri-Color.

Tri-Color is a highly visual tool that requires little to no training to verify if your hood is containing. It’s simple, easy, fast, and economical, making it the perfect solution for all fume hood users.
