Pacific Sentry LLC was founded in 2005 through a spinoff of Photonic BioSystems, Inc. in collaboration with Pacific Technologies.  Through the spinoff, Pacific Sentry effectively absorbed over 20 years of ammonia sensing R&D, know-how, trade secrets, and patent rights.  The company is now dedicated to providing high-quality, extremely sensitive ammonia sensors for commercial and non-commercial use.

The key competitive advantages underpinning the sensor technology include: cost-efficiency, sensitivity to ammonia, and robustness. With the ability to sense ammonia in a gas or liquid phase, detect trace amounts in the 0.005 ppm range, and manufacture at low cost, these sensors can be – and are – utilized in a wide variety of applications. By having a deep understanding of ammonia – in both gas and liquid phases – and expertise in ammonia-sensing technologies, Pacific Sentry can quickly and efficiently customize their sensors to provide ammonia sensing and monitoring solutions for nearly any application.

Through the technological successes achieved from their various ammonia sensor designs, formulations, and patent granted rights, Pacific Sentry is ensured to be a mainstay entity in the ammonia detection industry for many years to come.
