Digital Pressure Calibrators & Gauges

While the industries that use digital pressure test gauges have evolved, the need for durable, insightful, and highly functional equipment remains strong. We’ve built our digital pressure test gauges with environmental accuracy and performance flexibility in mind. Whether you’re dealing with hotter or colder ambient temperatures in your line of work, our digital pressure test gauges are entirely temperature compensated—from 14° Fahrenheit to 122° Fahrenheit (-10°C to 50°C). High-pressure measurements to low inches of water measurements are equally covered, as well as vacuum and positive pressure. Additel also offers panel mounting equipment, so you can position your pressure gauge exactly where it’s needed. Shop our models below for a solution that meets your needs!
