■ LED detector
Equipped with UV LED and VIS LED. ■ Reduced environmental and maintenance burdens Using LED instead of mercury reduces environmental burdens. ■ Applications Measurements of organic contamination in sewage treatment plant water, factory waste water, rivers, Features � UV LED allows it to have longer service life compared to conventional mercury lamp. Light source life' (V/LED Mercury lamp 20 years or more? 1 year ● Using LED reduces maintenance burdens and running cost. ● Periodically conducts wiper cleaning and zero point calibration automatically those ensure obtaining stable measurement result. 😊 Available for both water sampling method and submersion method with maximum depth rating of 1MPa (100m depth) equivalent. ● Measurement data can be saved in the converter and retrieved in CSV format using a USB memory.
Principle
The device continuously measures organic contaminants in the sampled water using absorptiometry. As optical structure, two optical paths in two wavelengths (UV LED and VIS LED) are used. Emitted LED light to be split into reference light and measurement light by the separator. The measurement light that passes through a sample and the separated reference light to be measured by designated photodiodes for each. This system structure significantly improved the temperature characteristic of UV absorbance.
Examples
Installation site: Sewage treatment plant
purpose of comparison of the UV absorbance measuring performance.
