The vacuum fine regulation and monitoring are required by particular tests as for example the Binder recovery by rotary evaporation conforming to EN 12697-3 (see \#rotary-evaporator--for-binder-recovery\#). This unit satisfy this requirement. For more details concerning the most common applications, see the Buyers guide in the Additional information.
The metal case house the high precision vacuum regulator valve and the digital display unit.

Range of regulation: 0 to 760 mm/hg
Resolution of digital display: 0.001 bar
Overall dimensions: 250x250x280 (h) mm
Weight approx.: 7 kg
