The RCP230N, designed by Infitech, is a hand-held portable vacuum gauge for non-fixed or short-term use. It measures vacuum levels from atmospheric pressure to 1.0E-2Pa. It features a large-capacity lithium battery that allows it to operate continuously for over 40 hours on a single charge. Automatic sleep and shutdown functions help extend the battery life, making it suitable for mobile inspection, field operations, and equipment maintenance.
