Academic labs and small teams rarely have budgets for $10k+ testing software—but that doesn’t mean you need to sacrifice functionality. There are affordable options that work for 80% of research scenarios, plus hacks to stretch their capabilities.

Free/opensource gems:

· Python + PyQt: Build custom interfaces with Python’s libraries (Pyserial for sensors, Matplotlib for graphs). It’s free, flexible, and great for small setups (1–16 channels).

· OpenVIsion: A lightweight alternative to LabVIEW, with basic data logging and device control. Good for students or simple tests.

· Dewesoft X Lite: Free for up to 4 channels—perfect for teaching labs or single-probe tests.

Budget paid options ($500–$3k):

· Omega OMB-DAQ-55: Bundles software with a 16-channel data logger. Handles pressure, temperature, and voltage—covers most research needs.

· National Instruments LabVIEW Community Edition: Free for non-commercial use, with a huge library of plugins for sensors and probes.

Hacks to boost functionality:

· Use Excel macros to import raw data from cheap software, then auto-generate graphs.

· Sync free software with hardware triggers (e.g., a $20 Arduino sending start/stop signals) to mimic expensive multi-device setups.

What to skip:
Avoid “all-in-one” software with features you don’t need (e.g., 3D modeling for a lab that only measures static pressure). A basic package with logging and simple graphs is often enough.
