UV Nitrate Sensor Calibration Standard 5mg NitraLED 500ml YSI 608072

The UV Nitrate Sensor NitraLED Calibration Standard has 5mg/L NO3-N and comes in a 946ml bottle. The calibration standard is filtered to remove any optical interference that can be present in other nitrate standards. The NitraLED calibration standard is recommended over any typical nitrate calibration standards as it provides optimal calibration of the EXO NitraLED UV Nitrate Sensor. To ensure the best performance, it is suggested that the EXO NitraLED Sensor is calibrated at a temperature that is close to the sample temperature.
