Both the Bluelab pH Probe and Bluelab Conductivity/Temperature Probe require
submersion in the liquid for a measurement to occur.
•
Do not pour concentrated nutrient solution or pH adjuster directly onto probes when in
the reservoir, as very strong acid may damage the probes or your alarms (if set) may
trigger.
Fit the (optional) pH probe holder to the stem of the pH probe
using a gentle twisting motion.
Place the pH probe into the reservoir and push the suction cup
onto the side of the reservoir but far enough down so the pH
probe tip is in the solution. The holder prevents damage to the
pH probe from banging onto the side of the reservoir with
movement of the solution.
Place the conductivity/temperature probe into the reservoir
selected.
