Nitrate sensor usage
The nitrate sensor's electrode uses a PermaFil (non-
refillable), ion-selective electrode. The reference
chamber is gel filled and sealed; therefore, no reference
filling solution is required.
The sensor is pre-calibrated at the factory. No need for
calibrating during the first 12 months from receiving.
After 1 year and if the sensor has been well maintained
we recommend doing recalibration. For information on
where to purchase calibration solution as well as
required calibration software please reference the ion
selective product pages at www.neulog.com. If there are
any questions please contact us at .
