pHionics Water Quality Sensors


The pHionics STs Series simplifies your water quality measurements with durable, noise-resistant and easy-to-use sensor/transmitters for temperature, pH, conductivity, dissolved oxyden or ORP (redox)


pHionics pH Sensor

The pHionics STs Series™ pH sensor provides accurate pH and temperature measurements to a datalogger or RTU for continuous water quality monitoring. A large, double junction reference cell provides accurate, stable pH measurements for long periods of time. In addition, isolation, differential amplification, and shielding eliminate background noise without draining the battery of the datalogger or RTU.

pHionics STs DO (Dissolved Oxygen) Sensor

The pHionics STs Series™ Dissolved Oxygen sensor accurately measures dissolved oxygen (0-20 mg/L or percent saturation) and temperature (0-50°C) over long periods of time with little maintenance required. It outputs two noise-resistant 4-20 mA signals compatible with most dataloggers or remote telemetry units. A narrow diameter allows the STs Series to go where other sensors cannot while a durable, chemical-resistant housing ensures many years in-use. The electrode tip (anode) has a large surface area that improves oxygen exchange consistency across the membrane while reducing the frequency of fouling.

pHionics STs ORP (Redox) Sensor 

The pHionics STs Series™ ORP sensor provides reliable ORP (redox) and temperature measurements to a datalogger, RTU, PLC, or SCADA system for continuous water quality monitoring. Accurate and low-maintenance operation is ensured with noise-resistant 4-20 mA analog signals and a large-volume, double-junction electrode. Typical electrode life is 2-4 years and, when needed, a replacement is easily installed thanks to pHionics’ patented pHiConn™ Connector System. In addition, the electronics are isolated to prevent ground loops and proprietary signal conditioning virtually eliminates background noise. Durability is guaranteed with chemical-resistant 316 Stainless Steel (titanium optional) and high-quality double O-ring seals that last many years, even in harsh conditions.

pHionics STs Conductivity Sensor

The pHionics STs Series™ Conductivity is a water quality sensor designed to pair with a datalogger or RTU for real-time data capture. A narrow diameter allows the STs Series to go places others can’t while the chemical-resistant housing ensures the sensor can stay there for many years. Proprietary electrode technology provides stable measurements to reduce calibration frequency.

Choose the Right Sensor for Water Quality Monitoring

Full article available at pHionics


Sensors are the backbone of any water quality monitoring system since they determine accuracy and reliability.  As such, it is best to start with picking the sensor(s) when designing a new system for applications such as pollution control, saltwater ingression studies, aquaculture, process control, etc.

There are many factors to consider when deciding what sensor is right for your application. Obviously, the most important aspects are whether the physical demands of your application are within the limitations of the sensor, but there are many other considerations that come into play. For instance;


Sensor Capabilities

Stability is important to consider because a sensor that requires calibration every week does not work for an application where an operator only visits the site every month.  Some sensors, such as those that measure conductivity, require calibration much less frequently than pH or ORP sensors, simply due to the nature of the sensor. As such, it is important to research electrode design to understand what unique features are beneficial. 


Physical Limitations

The next important considerations to verify that the sensor works for your application are the physical limitations, as outlined above.  Size does matter, at least when installing sensors into pre-existing systems such as wells or boreholes that may prevent the use of sensors larger than a certain diameter.  It also may be cost-prohibitive to use large diameter sensors in new projects such as groundwater monitoring, as drilling a wider hole can exponentially increase costs.


Signal Type

Each type of signal has its pros and cons.  For example, serial communication protocols like SDI-12 and RS-485 allow for multiple sensors to be connected in series, reducing the number of receivers necessary for large numbers of sensors in a small area. In contrast, 4-20 mA sensors require individual I/O ports for each sensor and can only transmit an analog signal that must be scaled by the receiver. Because of these differences, there is no single best signal for all applications, so it is important to understand the pros and cons of each type.


Features

What factors a sensor compensates for, along with the customizability of them, are also important to consider.  For example, conductivity temperature compensation can vary significantly depending on whether a sample is high or low conductivity, typically ranging from 1.8-4% respectively. Using a sensor with variable temperature compensation allows for more precise measurements across a wide range of samples. 

Other features that affect measurement accuracy include isolation and a solution-ground, both of which mitigate background noise.  Due to the sensitivity of water quality sensors, small amounts of electromagnetic interference can lead to inaccurate results.  


Ease-of-Use

Ease-of-use is also important because a sensor is worthless if it is too time-consuming to set up and maintain.  Digital sensors benefit from the ability to store calibration information and perform complex calculations but must have a good user interface to do so while also providing easy installation.  Analog sensors, on the other hand, are generally easier to set up, maintain, and troubleshoot but may not have as many features.
