Harvia LongRun Pro - Precision Temperature Sensor Cable

4.6

Best reliable extension for sauna owners needing longer sensor reach.

This essential cable solves the connectivity hurdles of larger sauna layouts by supporting reliable, long-distance sensor runs. While it requires a separate sensor purchase and is strictly non-returnable, it is the only way to ensure your heater’s thermostat remains precise across an extended installation.

Who it's for

  • Sauna owners prioritizing consistent heat and safety
  • Users seeking long-term durability in harsh sauna environments
  • Installers wanting seamless integration with existing Harvia systems

Who should skip it

  • Budget-conscious shoppers looking for affordable third-party alternatives
  • Owners of non-Harvia sauna equipment seeking universal compatibility
