Notes:

For alkaline conditions between pH 7 ~ 13 use a probe that has the –HT option.
For conditions above pH 13 contact Intech.

The pH model type probes are ideal for use with our LPI-pH pH transmitter, or with our pH-HR pH data logger (for the best possible accuracy with the LPI-pH or pH-HR, we recommend using a pH probe that includes an RTD Pt100 sensor).
