The LabSen® 371 pH electrode from Apera Instruments is engineered for precise pH measurement on smooth surfaces such as skin, textiles, leather, paper, and fabrics. Designed with Swiss sensor technology, this flat-glass pH electrode ensures fast, stable readings while being highly resistant to contamination and damage.

Key Features:

✔ Special Flat Glass Membrane – Designed for moist, solid, and semi-solid surfaces, featuring a PTFE compound structure that prevents clogging and ensures reliable, accurate readings.
✔ Multi-Porous PTFE Junction – The multi-porous Teflon material resists contamination, enhancing electrode longevity and measurement stability.
✔ Long-Life Reference System – Composed of a glass tube, AgCl, and a reference silver wire, this sealed system prevents electrolyte degradation and extends the electrode's lifespan.
✔ Blue Gel Electrolyte – Non-flowing design eliminates air bubbles, providing consistent, accurate measurements.
✔ Corrosion-Resistant POM Housing – The polyoxymethylene (POM) sheath protects against impact damage and corrosion, ensuring long-term durability.
✔ Swiss Sensor Technology – Guarantees high accuracy and reliability for pH surface testing.
✔ Broad Compatibility – Features a BNC connector, making it compatible with all pH meters that use BNC connectors, including:
???? Apera Instruments PH850, PC850, PH8500, PC8500, PH700, PH910, PC910, PH950, PC950, PH800, PC800, PH820, and PC820.

Compatibility:

???? Temperature Compensation: Requires a separate temperature sensor (e.g., Apera Instruments MP500) for automatic temperature compensation, or temperature must be entered manually.

Warranty:

???? 6-Month Manufacturer's Warranty ensuring reliable performance for surface pH measurements.
