THERMOVAC TM 101 & PIEZOVAC PV 101 - Handheld digital gauges
The all-in-one gauges
Combining a high-quality sensor with a modern processor technology in a compact and handy design.
The integrated screen allows for spot checking without the need for a separate local display. Even operation while completely under vacuum conditions is possible so you could monitor how well your vacuum packing machine is performing.
Thanks to their battery mode, alongside optional 15VDC mains power adaptor, the devices can be attached and operated at any pressure measuring point, and directly display or store up to 2,000 values for later evaluations and visualizations via the optional VACUGRAPH software.
You can also purchase a dedicated carry case for when it is integrated into a wider work-kit.

PIEZOVAC PV 101
Piezo-resistive silicon sensor
The PIEZOVAC PV 101 operates with an internal piezo-resistive silicon sensor able to measure from 1200 to 0.1 mbar.
Under the influence of pressure a thin diaphragm is bent, and on it‘s back a resistor-bridge is applied. The bending forces the measurement-bridge to come out of tune, which is a measure for the applied pressure.
The PIEZOVAC PV 101 has been specially developed for food sector deployments. Thanks to its detachable flange connection the size of the sensor is significantly reduced.
The exclusive use of its piezo sensor increases the battery’s service life so that the device is continuously ready for operation. With a measuring rate of minimum 50 ms, you are informed rapidly on the current pressure.
THERMOVAC TM 101
Piezo resistive pressure sensor combined with Pirani sensor
The THERMOVAC TM 101 combines a piezo-resistive pressure sensor for the upper and a Pirani sensor for the lower pressure range, the measurements made by this portable gauge are independent of the type of gas above pressures of 15 mbar (11.25 Torr).
It is capable of measuring pressures within the pressure range of 1200 to 5x 10-4 mbar (900 to 3.75 x 10-4 Torr).
This portable gauge can operate optionally as a data logger saving the pressure data during the measurement making it perfect for service personnel to check performance and log it as part of their process.
VacuGraph software
Measuring software for vacuum systems
Together with our vacuum gauges, the advanced VacuGraph™ software serves as the ultimate tool to visualize, analyze and save measurements on your PC in an efficient and easy way.
VacuGraph is self-explanatory and suited for all of our instruments with either USB, USB-C, RS232, RS485 or Bluetooth interface.
- The full version requires one license per PC.
- The lite version is free of charge.
What you get is:
- Saving of measurements.
- Graphical display and evaluation of measurements.
- Measurement data exportable as CSV files.
- Simultaneous communication with a random number of active gauges.
- Convenient leakage calculation: simply select pressure range with the cursor, enter chamber volume and the leakage rate is automatically calculated.
- Comfortable setting of all parameters of our measurement gauges (e.g. units, output characteristics, gas type correction factors, switch and switchover points etc.)
- Curve illustration and graph headings are easily changeable e.g. for quality assurance records.
- Firmware Update Assistant: benefit immediately from newly developed features and update gauge firmware simply yourself.
- Operating systems: Windows XP/Vista/7/8/10/11, Linux, MacOS.
VacuGraph accessory set
Optional VacuGraph accessory set
VacuGraph is a windows software for measuring data storage and PC analysis
The accessory set is a practical suitcase that includes software, USB interface cable and adapters.
This case provides protection for all parts and holds them in one place. The intelligent software allows online recording of measurements as well as the read-out of the PV 101 or TM 101 data memory. Measurements can be plotted as a diagram and exported as text files for further analysis.
Advantages:
- Easy to read LCD screen with long battery life via 9v battery
- Integrated flange for easy spot checking of systems
- Pressure measurement from 1200 to 5 x 10-4 mbar
- Gas correction factors stored directly on the unit, adjustable directly on the unit, or via dedicated software
- Ability to store multiple data points and export to PC
- Carry case provides a safe way to transport gauge and accessories from site to site
