The pHionics pHishgard™ is a device that easily slips over the electrode and provides additional protection from large fish scraping or otherwise damaging the electrode tip with their fins. It works by expanding and contracting at the top via handles, similar to scissors. This allows the pHishgard™ to lock in the groove at the top of the sensor and stay securely in place when force is applied from any direction.
STs Series sensors are constructed from high-quality, durable materials that can be stored for long periods of time. The only weak point is the electrode, which can be damaged or expire during storage in the wrong conditions. These conditions vary depending on the type of electrode, which is why we have different storage instructions for each sensor.
Sensors are the backbone of any water quality monitoring system since they determine accuracy and reliability. Learn more about important characteristics to consider when choosing a sensor for your application.
