Product Description

TT-Na-pH Brine pH Sensor

SKU: TT-Na-pH-2110

Digital Smart Sensor Technology (DSST)

This sensor is available with our digital smart sensor technology. This plug and play sensor has a quick connect fitting, eliminating the need for hard wiring to the analyser. On-board sensor memory allows the storage of calibration dataanalyser configurations and sensor service history. This allows the sensor to be conveniently maintained and calibrated off-site or in the laboratory and pre-programmed with calibration data and analyser configurations.  This stored information automatically uploads to the analyser upon connection and eliminates the need for any interaction with the analyser, greatly simplifying the change-out of sensors. A service log stored on the sensors is ideal for maintenance and quality assurance records.

Application Specifications

Recommended Applications

Specifically designed for use in Brine.  Any process application where high levels of brine may be present. Saturated sodium resistant pH glass ensures accurate readings, stability and longevity in brines. Any measurement where aggressive chemical cleaning is needed to remove fouling or low-maintenance operation is required with minimal cleaning and re-calibration.
