AQUAlogger® 525

Mini Temperature and Depth Logger

The AQUAlogger® 525PT is a compact, self-contained logger that measures and logs temperature and pressure-derived depth data. Designed for autonomous oceanographic and environmental deployments, it provides a practical way to collect long-term field measurements without the complexity of larger wired systems or externally powered instruments.

As the successor to the AQUAlogger® 520, the 525PT introduces expanded memory, flexible logging regimes and improved setup control, supporting reliable temperature and depth monitoring in a simple, deployment-ready package.

 

KEY FEATURES

  • Self-contained temperature and pressure logging
  • Pressure-to-depth conversion
  • Compact wireless design
  • Up to 5 years of battery life
  • User-friendly data upload
  • Flexible Sampling Regimes: Continuous and burst sampling options with rates up to 8 Hz and burst averaging

APPLICATIONS

  • Oceanographic and environmental research
  • Environmental impact assessments
  • Temperature distribution surveys
  • Long-term time series at fixed observatories
