The P4 and P5 Portable Gauges are complete, all-in-one gauge displays that operate off an integrated battery, making them the perfect solution for service personnel to check vacuum performance at specific points in a system, ensuring operational efficiency. These convenient handheld devices eliminate the need for a gauge/controller setup or an external power supply, allowing for quick and easy spot measurement checks. Their compact, portable design ensures they are always ready for on-site service calls, maintenance checks, and flexible system diagnostics.

The P4 and P5 measuring systems offer independence from mains power, enabling seamless operation in field environments. Both models are equipped with advanced sensors for precise vacuum measurement. The P4 features a piezoresistive sensor with a pressure range of 2000 to 1 mbar, making it ideal for rough and fine vacuum applications. The P5 is equipped with both a piezoresistive and Pirani sensor, providing a broader range between 1200 to 5 x 10⁻⁵ mbar.

Both gauges include onboard memory for data logging, allowing users to store multiple measurement series directly on the device. This supports effective system analysis and performance tracking. Additionally, the P4 and P5 feature USB-C and Bluetooth® LE connectivity, allowing users to export and visualize data for further analysis.

If you work with vacuum systems, much like those found in research or lab environments, you already know that accuracy isn’t optional – it’s essential. Which is why we’ve extended our range of vacuum measurement tools to include our new Edwards P4 and P5 Handheld Vacuum Gauges. These aren’t just any run-of-the-mill vacuum gauges—they’re dependable, intuitive tools that take the guesswork out of setup, spot checks, and maintenance. We designed them with you in mind, boasting a sleek design, large graphic display, and a 4-way keypad that makes navigating operation and reporting almost effortless. When you’re busy solving complex problems, your tools should help, not hinder.
