Description
The Model TCOH with the UV254 Sensor utilizes state of the art UV 254nm optical absorbance technology to measure organics in water.
Many dissolved organic substances have spectral characteristics capable of absorbing UV light at the wavelength of 254 nm. A UV source produces UV light radiation that passes through the optical path. The receiver analyzes the UV pulses at two different wave lengths, a measurement wavelength (254 nm) and a reference wavelength which is not influenced by the presence of organic compounds. This results in accurate, repeatable measurements which can be read as a scalable mA value.
