IPA: /ˈflʊə.rɪˌmiː.tər/
KK: /flʊəˈrɪmətər/
An instrument used to measure the intensity of fluorescent light emitted from a sample when it is exposed to a specific wavelength of light.
The scientist used a fluorimeter to analyze the samples for their fluorescent properties.
Fluorimeter → It is formed from "fluor" (from Latin *fluere*, meaning to flow) and "-meter" (from Greek *metron*, meaning measure). The word refers to an instrument that measures the flow of fluorescence.
Think of 'flowing' light ('fluor') being 'measured' ('-meter') — that's what a fluorimeter does.
