Keller manufactures a wide range of digital pressure indicators from 1.3″ x 0.7″ x 0.4″ OEM displays to 3″ diameter high accuracy gauge. Keller gauges use an absolute or sealed gauge reference which can be manually reset. Keller gauges are wash-down rated (IP-65).

Features include Tare functions, Peak or Min/Max recording mode, and o-ring swivel seal to allow rotation even under pressure. Battery life is typically 1000 hours of continuous operation when not in recording mode.
