The Leybold PIEZOVAC PV201 and THERMOVAC TM201 are portable vacuum gauges from Leybold.
Measuring Range: The PIEZOVAC PV201 utilizes piezoelectric technology and offers an absolute pressure measurement range of 2000 to 1 mbar; the THERMOVAC TM201 combines piezoelectric and Pirani sensors and offers an absolute pressure measurement range of 1200 to 5 × 10⁻⁵ mbar. Both models offer a relative pressure measurement range of -1060 to +1200 mbar.
Advanced sensors with temperature compensation ensure stable and accurate readings, while sophisticated electronics deliver consistent and repeatable results.
An intuitive graphical display and simple control menu provide quick access to real-time data, facilitating rapid decision-making and process adjustments.
Leaks can be identified by tracking the rate of pressure rise, assisting in maintaining system integrity, maintenance, and quality control.
A built-in data logger stores time-stamped measurements, transfers data via USB-C or optional Bluetooth®, and analyzes it using Leybold VacuGraph™ software.
Both products feature a lightweight yet rugged design for use in harsh environments, while maintaining the same compact form factor for portability and ease of use.
