pH probe calibration
Clean and calibrate the pH probe at least every 30-50 days and at the end of each cultivation cycle. The pH probe is the most sensitive part of the NIDO ONE V2, and proper maintenance is essential for stable readings over time. Deposits of salts and contaminants on the bulb junction can cause erroneous readings and blockage of the pH probe, therefore routine maintenance is necessary.
Never store, rinse or immerse the pH probe in osmotic/distilled water. Osmotic water will alter the solution chemistry of the probe, causing it to break down.
It is recommended that pH calibration is carried out prior to first use to ensure that pH readings are accurate.
1. Disconnect the IN and OUT hoses.
2. Remove the pH probe by loosening the pressprobe.
3. Soak the pH probe in pH probe cleaning fluid for 1-2 hours until the glass bulb is covered.
4. Clean the pH probe with the supplied brush, avoiding touching the glass bulb with your fingers.
5. Wash the pH probe under running water and dry the outside with a clean cloth.
6. Insert the pH probe as far as it will go and tighten the press-probe.
7. Calibrate the pH probe in the Settings > pH > Calibrate in menu, following the instructions in the NidoPro app.
8. If the calibration fails, immerse the probe in KCI for 24/48 hours.
9. Repeat the pH probe calibration, if the instrument does not allow calibration, replace the probe.
10. Connect the IN and OUT hoses.
