Digital differential pressure gauge 990

The differential pressure gauges 990 Display are for air and non-aggressive gases and will be used to measure differential pressure, overpressure and vacuum. They offer one adjustable pressure range and two output signals, which can be selected in the menu. The type 990M has a manual zero offset calibration, the type 990A has an automatic zero offset calibration. Monitoring of air and non-aggressive gases.
