NitraLED calibration standards come in 946 mL bottles and are filtered to remove any optical interference that might be present in other nitrate standards.
NitraLED calibration standards recommended over other nitrate calibration standards to provide the best possible calibration of the EXO NitraLED sensor.
Note: For best performance, YSI recommends calibrating EXO NitraLED at a temperature close to the sample temperature
