The Additel 685Ex Digital Pressure Gauge is an intrinsically safe, fully temperature-compensated digital pressure gauge for use in hazardous areas. It uses microprocessor control and silicon pressure sensors to deliver stable, repeatable measurements in field and process applications.
A 3.4-inch colour touchscreen with tempered glass provides menu-based setup and operation. The enclosure is IP67 rated for dust and water protection.
An internal barometric sensor (50 Pa accuracy) enables gauge, absolute, and atmospheric pressure measurement. Optional internal data logging stores over 10 million records, including date, time, pressure, and temperature.
