Anton APM 155 Differential Pressure Meter
The Anton APM 155 Differential Pressure Meter is a robust, professional instrument engineered for medium pressure and strength testing applications up to 2 bar (2000 mbar). Designed for use by gas engineers, plumbers, and mechanical technicians, it delivers reliable accuracy, intuitive operation, and modern data handling features that support compliance and professional reporting.
Built to perform in demanding site conditions, the APM 155 combines durable construction with advanced digital technology. Its large, high-resolution colour display ensures excellent visibility, while the simple, menu-driven software allows engineers to move quickly between tests, settings, and stored results with minimal training.
Anton APM 155 Key Applications:
The Anton APM 155 supports a wide range of essential pressure testing tasks, including:
- Let-by, stabilisation, and tightness testing
- Timed pressure tests with configurable start and finish pressures
- Timed strength tests with user-defined duration and pass/fail limits
- Differential and gauge pressure measurement
Each test can be run using elapsed time monitoring or countdown timers, with alerts to notify the user when a test phase is complete. A two-stage exit system helps prevent accidental termination, protecting test integrity and logged data.
Measurement Performance:
The APM 155 offers precise and flexible pressure measurement suitable for multiple standards:
- Measurement range: 0 to 2100 mbar
- Resolution:
- 0.1 mbar up to 999.9 mbar
- 1 mbar above 1000 mbar
- Accuracy: ±2% of reading
- Eight selectable pressure units, including mbar, kPa, PSI, mmHg, and inH₂O
A simple push-button zero function allows fast setup before testing begins, saving valuable time on site.
