Matter Lab Pressure Gauges

matterlab_pressure_gauges provides Python drivers for pressure gauges used in Matter Lab automation workflows.

The package currently includes:

• Gauge: abstract base class for pressure gauge interfaces
• InficonPCGGauge: serial driver for Inficon PCG gauges

Installation

Use the matterlab conda environment and install the package in editable mode during development:

pip install -e .[dev]

The package depends on matterlab_serial_device for serial communication.

Quick Start

from matterlab_pressure_gauges import InficonPCGGauge

gauge = InficonPCGGauge(com_port="COM4", address=1)
print(gauge.pressure, gauge.unit)
print(gauge.error)
print(gauge.product_name)

Testing

Simulation tests are the default and are the only tests intended for CI enforcement.

One-click local sim run:

python examples/test_sim.py

Direct pytest run:

pytest

Real hardware tests are present for manual validation but are skipped unless explicitly enabled.

Run real tests with explicit hardware parameters:

pytest tests/test_inficon_gauge_real.py --run-real --com-port COM4 --address 1

You can also provide the settings through environment variables:

set PRESSURE_GAUGE_COM_PORT=COM4
set PRESSURE_GAUGE_ADDRESS=1
pytest tests/test_inficon_gauge_real.py --run-real

Examples

Additional examples live in examples/README.md:

• examples/test_sim.py for the sim suite
• examples/real_devices.py for readable hardware usage examples

Development Notes

• Source code lives under src/
• Pytest uses src as the import root
• Hardware-backed tests are marked with @pytest.mark.real
• Generated coverage, build, and cache artifacts are ignored
