Edwards Vacuum Unveils Advanced P4 and P5 Bluetooth® LE Handheld Measuring Gauges

GLOBAL | 3 April 2025 | 3 min

Edwards Vacuum has announced the launch of its latest innovation in vacuum measurement technology: the P4 and P5 Bluetooth® LE Handheld Measuring Systems.

These cutting-edge gauges are designed to deliver precise and reliable performance across a variety of applications, meeting the demanding needs of modern industrial and R&D environments.

Key Features and Benefits

Wide Measurement Range: Capable of measuring absolute pressures from 2000 to 5x10^-5 mbar and relative pressures from -1060 to +1200 mbar.
High Precision: Advanced piezoresistive and heat conducting Pirani sensors provide accurate and reproducible measurements.
User-Friendly Interface: Large graphic display with intuitive menu navigation for easy operation.
Data Logging: Integrated data logger with USB-C and optional Bluetooth® LE for seamless data transfer and analysis.
Durable Construction: Built with high-quality materials including stainless steel and ceramic for long-lasting performance.
Versatile Connectivity: USB-C interface and optional Bluetooth® LE for flexible data management.

Innovative Measurement Principles

The Edwards P4 utilizes a piezoresistive sensor for high-pressure measurements, detecting changes in electrical resistance as pressure is applied, providing highly accurate readings for absolute pressures up to 2000 mbar.

The Edwards P5 combines a piezoresistive sensor for high-pressure measurements with a heat conducting Pirani sensor for low-pressure measurements.
The Pirani sensor measures the thermal conductivity of the gas, allowing for precise measurements down to 5x10^-5 mbar.

Typical Applications

Vacuum System Monitoring

The continual monitoring of vacuum chambers and systems, for optimal tightness and performance.

Industrial Processes

Ideal for monitoring processes in manufacturing and research environments.

Quality Assurance

Essential for documenting and comparing pump down characteristics for audits, quality control and field service.

Leak Detection

Effective for identifying and addressing leaks in vacuum systems.

Our new P4 and P5 Series represent the pinnacle of vacuum measurement technology. With their wide measurement range, high precision, and user-friendly interface, these gauges are designed to meet the rigorous demands of modern industrial environments. The integration of Bluetooth® LE and USB-C connectivity ensures seamless data management, making these gauges an invaluable tool for our customers.
