Product Description

TT-WW-pH Waste Water pH Sensor

SKU: TT-WW-pH-2105

The Turtle Tough Waste Water pH sensor is unlike anything the waste water market has ever seen before. This space has been dominated by glorified lab electrodes being passed off as “industrial” units and expectations of performance and serviceability are generally low. The Turtle Tough Waste Water pH Sensor will challenge those expectations with its unique formulation to resist fouling, dehydration and provide a service life well beyond those competitors.

Continuous monitoring of waste water presents many challenges across the mining and manufacturing industries. For many facilities, inconsistent flows mean that sensors can dry out if not installed correctly, causing premature failures and ruining measurements. Additionally, there are often contaminants in waste water that will interfere with accurate measurements such as grease or oils that clog references and other components that will coat the measurement elements of sensors.

Turtle Tough sensors are specifically designed for your individual waste water monitoring requirements. The Extreme dehydration option allows sensors to be left dry for very long periods of time and still respond instantly and dynamically on re-entry to solution. This solution has been a huge windfall for manufacturers with batch processes or variable waste water flows, reducing sensor failure and man hours spent removing and changing sensors. Coat resistant sensor elements and general physical strength allow for strong mechanical cleaning of sensors that have been fouled by inorganic material or surface coatings, further increasing sensor lifetime in the field.

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.
