Sensorex knows you would rather be relaxing by the pool than worrying about maintaining your pH and ORP sensors. That’s why we developed the Pool Plus line of sensors. No more guessing if your sensors are working. With the Pool Plus electrode you’ll know when it’s time to replace your sensor. The salt crystal reference provides enhanced performance and provides a clear visual indication when the sensor’s reference fill is spent.

The Sensorex TCSP toroidal (inductive) conductivity sensors feature a wide measurement range and dependable toroidal technology over the range 0-2000 ms/cm. Resistant to corrosion, coatings and fouling common to contacting conductivity sensors, the TCSP3020 is designed for a trouble-free and long service life. PEEK (unfilled, polyetheretherketone) is the standard material of construction and has a wide solvent tolerance and temperature stability to 200 degrees C. The TCSP Models feature 3/4″ MNPT for submersion installation.

The GT/GG/GC sensors are great for testing samples with high temperatures such as industrial wastewater. A double salt ring reference design ensures constant refence concentration for increased stability over time.

Applications such as pulp and paper or dye manufacturing and industrial wastewater treatment may expose pH probes to harsh conditions and chemicals. A differential pH probe utilizes a special measurement technique, which extends the working lifetime of the sensor in challenging applications. Replacing the sensor reference ( salt bridge ) and buffered electrolyte solution can extend working lifetime, which saves timely, costly replacements. Our SD7420CD features differential sensor technology with a direct 4-20mA output, so it can be integrated into control systems without the use of a transmitter or controller. Utilizes differential measurement technology for extended sensor lifetime No transmitter or controller required Easy and infrequent maintenance Constructed of chemically-resist
