"Luminometer" Natural Recordings by Native Speakers
A luminometer is a device used to measure the intensity of light emitted by a sample, typically in bioluminescence assays. It is often used in scientific research and quality control to determine the amount of light produced by a biological or chemical reaction. The luminometer is usually based on a photomultiplier tube (PMT) or a light sensor that converts the light into an electrical signal, which is then measured and displayed as a unified index of light emission.
The Lumineers is an American folk rock band known for their acoustic-based music, introspective lyrics, and raw energy.
