Bullseye Precision Vacuum Gauge Piezo

Bullseye Precision Vacuum Gauge Piezo


The Bullseye Precision Gauge Piezo-775i provides accurate and reliable vacuum reading in the rough vacuum range of 1 to 775 Torr and has 11 additional measurement units.



Standard With Bluetooth
Clear selection

The Piezo-775i utilizes patented visual graphing capabilities that include a pump-down graph, autoscaling, and a bar graph.

The Bluetooth version can also transmit vacuum information to cell phones or tablets. There is also a cloud program, compatible with the Bluetooth version, which allows the user to view vacuum processes and record data.

The Piezo-775i is an excellent gauge for rotary evaporation, schlenk line monitoring, botanical oil processing, falling films, altitude simulations, and vacuum process monitoring.

The unit is CE, CSA, UL, and RoHS certified. The gauge has a powerful magnet and kickstand for support and hands-free operation.

The long battery life and different measuring units allow the user to monitor vacuum continuously. The gauge is calibrated to an NIST standard ensuring reliable measurements every use.

The included sensor is hermetically sealed and isolated and made from stainless steel to ensure lifespan and durability.
