Product description
The DVR 2pro is a fully electronic, versatile vacuum gauge for measurements from atmospheric pressure down to 1 mbar. All wetted parts are made from chemically resistant materials suitable for demanding laboratory environments. The instrument combines a large graphical analog display with digital values to show trends and allow accurate readings. The pro version features a rear 9 V battery compartment for easy replacement and a wider range of connection fittings for flexible laboratory use. Items supplied include the vacuum gauge with integrated sensor, 9 V alkaline battery, support rod, connection parts and manual.
