The Turtle Tough pH Sensor for Solvent Extraction is one of our proudest achievements. With few viable alternatives in the market place the development of this product was entirely customer driven. After many incarnations this product has emerged as a genuine triumph and now has a long history of success. Solvent extraction and recovery are generally associated with three distinct problems: Strong acids, organic solvents and dissolved gases. Organic solvents are of particular concern, as they attack the housings and connections of sensors and cause interference and damage to reference junctions. For years we have worked closely with a range of manufacturers who use solvent extraction as a core part of their process; from Nickel and Uranium processing to Pharmaceutical manufacturers, to develop a sensor that would go on to save them countless dollars in sensor costs and increase their process yields through better accuracy. The TT-SX-pH Sensor is the only sensor they have been able to use in their tanks, where our competitors couldn’t supply a sensor that lasted more than a couple of days. Solvent resistant bodies and sealants, combined with our triple junction reference systems allow the sensors to stay operational for more than 10 times longer than our best competitor. 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 data, analyser 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.
