Pacific Sentry LLC was founded in 2005 through a spinoff of Photonic BioSystems, Inc. in collaboration with Pacific Technologies. Highly specialized in the ammonia detection field, this company produces the most ammonia-sensitive sensors on the market, capable of detecting traces of ammonia down in the 0.005 ppm (parts per million) range. These sensors are functional for gas/air and in-water/aquatic environments.

Pacific Sentry is dedicated to providing high-quality, extremely sensitive ammonia sensors for commercial and non-commercial use. This ammonia detection technology can be utilized in a wide range of applications; from the medical industry to the agriculture industry, from aquatics to gaseous. With the ability to quickly and efficiently customize their sensors, Pacific Sentry provides ammonia sensing and monitoring solutions for nearly any application. With their technological success in ammonia detection and patent granted rights, Pacific Sentry is ensured to be a mainstay entity in the ammonia detection industry for many years to come.

Pacific Sentry actively seeks strategic relationships with companies and individuals that result in mutually rewarding benefits. These relationships take the form of IP licensing agreements, corporate partnerships, joint ventures, and corporate/private funding investments. The synergistic effect created when working with a strategic partner is highly valued at Pacific Sentry. Developing relationships (and business arrangements) that further the technological advancement and commercialization efforts of their technologies are a cornerstone of the company's business model.

Pacific Sentry makes every effort to properly and promptly address and define all business opportunities with outside parties.
