Stauff Corp.’s PPC-04-plus is the latest generation in its line of handheld hydraulic-system testers. The compact mobile tester measures pressure, temperature, flow rate, frequency and speed in mobile and industrial hydraulic systems. It features robust construction and an oil-resistant rubber coating to withstand impact, vibration, dust and moisture (protection class up to IP67), and is designed for use in harsh conditions. It is available with either two analog sensor inputs or a CAN interface (PPC-04-plus-CAN) for connecting up to three digital sensors. According to the company, measured values can be read quickly and reliably—even in low light situations—on its multiline, backlit LCD graphic display. Using the USB port and the included software, measurement values can be transferred to the PC, where they can be displayed, analyzed and further processed.
