GSR2 Biofeedback Machine

A pocket-sized GSR biofeedback meter for stress and relaxation training. The GSR2 measures galvanic skin response — one of the body's most responsive stress signals — and gives instant audio and visual feedback. A practical, affordable tool for meditation, breathwork, and self-awareness practice.

$109.95

The GSR2 measures galvanic skin response (GSR) — minute changes in skin conductivity caused by stress-related sweat gland activity. As tension rises, the device produces a higher pitch tone; as you relax, the tone falls. Resting two fingers over the sensing plates is all that is required. Over repeated sessions you learn to recognize the body's signals and use breathing, meditation, or other relaxation techniques to lower the pitch and bring your nervous system back into balance.

The GSR2 Biofeedback Machine is a home biofeedback device that helps you track stress levels by translating tiny tension-related changes in your skin into an audible tone.

  • Designed to support relaxation training and stress awareness
  • Higher tone indicates stress, lower tone indicates relaxation — audible cues guide your practice
  • Pairs well with deep breathing, guided meditation, or other relaxation methods
  • Cordless and easy to use — rest two fingers on the sensing plates
  • Skin resistance range: 1,000 ohms — 3,000,000 ohms
  • Variable frequency range: 0 to 40,000 Hz
  • Power: 9V battery (included), battery current in use < 2.0 mA
  • 2.5 mm output jack for 8 ohm earphone and output meter
  • 3.5 mm input jack for thermistor and electrodes
  • GSR2 Biofeedback Machine with cordless finger sensors
  • Earphones (provides tonal GSR or temperature feedback via internal speaker or headphones)
  • 9V battery
  • Operator's manual

1-year manufacturer warranty.

How do I use it?

Rest two fingers over the sensing plates and listen to the tone — higher pitch indicates stress, lower indicates relaxation. Practice with deep breathing or meditation to lower the tone.

What does it measure?

Galvanic skin response (GSR) — subtle tension-related changes in skin conductivity that reflect activity in your nervous system.

Does it require batteries?

Yes — a 9V battery is included.

Is it cordless?

Yes — finger sensors are built directly into the unit, no wires required.
