Product Information
The TUSA SCA-150U Imprex Pressure Gauge is a heavy-duty, Imperial-reading analog pressure gauge built for divers who pair a wrist-type dive computer, such as the IQ-650, IQ-750 or IQ-900, with a separate air pressure readout. It displays continuous air pressure and temperature in a low-profile rubberized boot and reads 5000 psi/400 bar, with a 4350 psi/300 bar maximum working range.
Who it is for
This gauge suits divers who run a wrist-mounted dive computer for depth and dive-time data but still want a dedicated, easy-to-glance pressure gauge on a hose, including night divers and anyone diving in low-visibility conditions. The luminescent dial glows brightly enough to be read in the dark and contains no radioactive materials.
