Light air pollution such as ambient light as well as light given off from various other probes can trigger disturbance and imprecise analyses. The website or the probe need to as a result be convered. Transmission probes With transmission probes, the light emitter and sensing unit are put opposite each various other on pulsatile tissue such as a number or ear.
Reflectance probes With reflectance probes, the light emitter and also sensing unit are placed side-by-side on a level body surface.
