Plate IX · Bench readouts

Raw values from calibrated instruments.

Independent measurements — HRV accuracy (Polar H10 + Kubios HRV), red-light irradiance, infrared sauna EMF, dissolved-hydrogen ppb — with raw values, units, uncertainty, and capture timestamps.

§ Awaiting bench shots

Hands-on testing is in progress. As measurements ship, they appear here automatically — each row links to the brand review and shows the instrument used, the metric, the value with units, and a capture timestamp.
