Hanna HI1048S pH electrode Clogging Prevention System
The Hanna HI1048S pH electrode Clogging Prevention System is a refillable glass-body pH electrode designed for high-performance measurement in challenging samples such as wine, must, and other viscous or colored liquids. Equipped with Hanna’s CPS™ (Clogging Prevention System) and a double junction reference, this probe ensures long-term stability, fast response, and resistance to clogging—common problems in traditional ceramic junction designs. The screw cap connector and 1-meter cable provide secure and flexible integration with compatible meters in both laboratory and field settings.
Key Features
CPS™ Technology – Open Junction Design: Replaces standard ceramic junctions with Hanna’s patented Clogging Prevention System, using ground glass and PTFE to maintain electrolyte flow and prevent fouling in colored or high-solid samples.
Double Junction Reference: Isolates the reference system from the sample, significantly extending electrode life when used in solutions containing proteins, sulfites, or organic solvents.
Refillable with 3.5M KCl: Designed for long-term use, this electrode allows electrolyte replenishment to maintain performance and reduce drift.
Dome-Shaped Glass Tip (8 mm): Ideal for ensuring good contact in semi-solid and viscous samples such as must or concentrated juices.
Robust Glass Body: Offers high chemical resistance and excellent thermal stability within a wide temperature range.
Screw Cap Connector: Provides a tight, reliable connection with compatible Hanna instruments, ensuring stable signal transmission.
Maintenance-Friendly Design: No temperature sensor or amplifier reduces complexity and simplifies routine care.
