Modular design for easy maintenance, greatly reducing on-site downtime
These modular pressure controllers combine cutting-edge control/measurement technology, modular design, and user-friendly features. The Additel 773 controller series is optimized for low pressure work by utilizing Additel’s proven low-pressure pump technology in combination with control capabilities that revolutionized the industry as seen in the well-known handheld model ADT760. For users who require automated production, test, and calibration, Additel has the workload covered with these pressure controllers. The ADT773 can be quickly outfitted with two controlling modules and one reference barometric module to cover a wide pressure range.
