American Marine Pinpoint Nitrate Probe
PINPOINT® Nitrate Replacement Probe is designed especially with your purpose in mind. It features long, continuous duty expectancy, fast response and, most importantly, is non-toxic to your system.
Maintenance: Clean the probe tip frequently (every 3 ~ 4 weeks) using a soft toothbrush. Push the probe tip down into the wet bristles and rotate the probe 3 ~ 4 times. This will clean the inner surfaces of the probe as well as the sensing glass and reference junctions. Most probes will last 12?18 months (continuous duty). They should be replaced once they cannot be calibrated. Check calibration monthly to verify your readings and refer to your owners manual for directions and specification on each monitor/controller.
