ATi Q46P/R pH and ORP Monitors

Continuous water quality monitoring of pH/ORP
 
 
The Q46P pH/ORP monitor provides the combination of durability, accuracy, and versatility required for virtually any pH monitoring or control application.
 
The Q46P pH monitors can be paired with our Q25 differential sensors. For this type of sensor, the silver/silver chloride reference element has been replaced by a pH sensitive glass electrode identical to the measuring electrode. This second glass electrode is housed in a chamber filled with pH 7 buffer which provides a stable reference. A high surface area reference junction electrically connects this reference system to the pH measuring element. The result is that pH is measured by the voltage difference between the two pH sensitive glass elements.
