Hanna HI72911D Titanium Body pH Electrode for Boilers
The Hanna Hanna HI72911D Titanium Body pH Electrode for Boilers is a high-performance pH electrode specifically engineered for monitoring pH levels in boiler systems and other high-temperature industrial water applications. Thanks to its titanium body, which also functions as a matching pin, this electrode offers enhanced durability and stable signal transmission even under challenging conditions.
Additionally, its flat-tip design, combined with a PTFE junction and polymer electrolyte, ensures long-lasting performance in chemically aggressive and high-pressure environments.
Key Features
Titanium Body with Matching Pin: Ensures maximum resistance to chemical corrosion while eliminating ground loop errors in high-conductivity environments.
Flat Tip Design: Minimizes fouling and allows for easy cleaning, which is ideal in boiler systems where scale and residue are common.
Built-in Temperature Sensor: Enables automatic temperature compensation, improving measurement accuracy during temperature fluctuations.
Amplified Signal: Offers enhanced stability and resistance to electrical noise from nearby motors and pumps.
DIN Connector: Provides quick and secure integration with compatible pH meters.
