Precision Vacuum Monitor

– by Lab Society

Vacuum Monitor
The Lab Society Precision Vacuum Monitor (LS-PVM-1) & (LS-PVM-2) allows for real-time analytics and data logging. This means that you will always know if your system is achieving the optimal vacuum pull.

We built the devices that we wanted to use in our own labs, and we created the most practical and functional thermocouple vacuum gauges yet.

We’ve added a few key features that are unavailable in other vacuum monitors to give you the best bang for your buck on the market.
Precision Vacuum Monitor

Compatible with EliteLab.


  • data logging via USB or Bluetooth (depending on model chosen)
  • digital vacuum gauge with visual display
  • portable
  • multiple measuring units
  • graphical and numerical output
  • hands-free operation via a kickstand (LS-PVM-1) or a rod support (LS-PVM-1 & LS-PVM-2)
  • easy, quick troubleshooting of the system
  • protective outer case (only on LS-PVM-1)
  • multiple thermocouple inputs (only on LS-PVM-2) 
  • rugged thermocouple

Unleash the power of systematic data.

The data that our Precision Vacuum Monitor logs can be sent via either Bluetooth or Micro USB to a computer or compatible device. We are firm believers in the power of logging data and measuring performance over time.

Eliminate guesswork.

Through accurate data logs, you can get actionable insights into your lab’s performance, increase your efficiency, and improve your productivity.

Real-time, visual graphing.

The Precision Vacuum Monitor also incorporates a real-time visual graphing feature, which allows you to monitor your system in the absence of a computer or compatible device. The on-screen data display allows you to quickly identify vacuum pressure trends, so you can see if the vapor pressure is too high or if there is a leak in the system.

Highly portable.

The monitor has a long battery life and supports a wide variety of measuring units, including Torr, micron, and inches of mercury. Always thinking about the end result first, we designed this vacuum gauge to be portable and highly functional.

For the LS PVM-1, we even put a magnet on the back of the Bluetooth gauge so you can attach the monitor to magnetic surfaces near the system. This unit’s case also features a kickstand, which allows you to easily prop it up on a table or desk.

Note: We recommend this monitor in conjunction with our packable and non-packable distillation heads (which have an attached condenser) or our detachable condenser.
