NitraLED Kit with UV Nitrate Sensor

NitraLED kit for EXO2 / EXO3 probes, includes UV nitrate sensor, alignment ring and cleaning brush. Utilizing state-of-the-art UV LED technology, the NitraLED™ kit includes an optical nitrate sensor designed for long-term, low-drift monitoring. Built-in corrections for Natural Organic Matter (NOM) and turbidity minimize interference in freshwater environments. Its compact form factor allows seamless integration with any EXO sonde. It must be installed on an EXO sonde to operate.
