​​Pre-pHault & Sentinel Sensor
​​​​What is pre-pHault? ​
It is a diagnostic feature s​howing the health of a mV sensor (pH, OPR or pION) on the transmitter
 ​What is the requirement?
Customer would have to purchase a SENTINEL enabled electrode, only available on SP3 sensor platform.


​The SENTINEL features allows the Model LXT 330 transmitter to provide Pre-pHault diagnostic information about the accuracy of a pH, ORP or pION measurement. The SENTINEL displays a filled triangular gauge that decreases proportionally to the degradation of the reference electrode, a filled gauge indicates a properly functioning measurement while the emptying gauge indicates the remaining life of the electrode. This Pre-pHault diagnostic alerts the user to potential problems and the remaining life before the measurement fails.​
