How to Use:
Using a rod to measure nutrient conductivity involves heating the sensor head of the probe in the solution, and then measuring and reading the conductivity value on the stem indicator.
1. Heat the sensor head and put the probe in the nutrient solution for 1?2 minutes to reach the temperature of the nutrient solution.
2. Measure the conductivity, briefly remove the rod from the solution, and then put it back for 1?2 seconds.
3. Read the conductivity value, remove the rod from the
