LabSen® 833 combined pH/temp. electrode for strongly acidic solutions and hydrofluoric acid (HF)

The LabSen® 833 by Apera Instruments is a high-precision pH electrode with an integrated temperature sensor, specially designed for measuring strongly acidic solutions (≥3 pH), including hydrofluoric acid (HF) solutions up to 1g/L. Built with patented Swiss sensor technology, it offers high accuracy, durability, and resistance to HF corrosion.


Key Features:

Swiss Patented Technology – Ensures superior accuracy and long-term reliability.
LabSen HF Glass Diaphragm – Resistant to hydrogen fluoride corrosion (1g/L) and 10x more impact-resistant than standard electrodes.
Silver Ion Trap Reference System – Prevents silver sulfide contamination, extending electrode life.
Non-Flowing Blue Gel Electrolyte – Eliminates air bubbles for stable, precise measurements.
Integrated Temperature Sensor – Enables automatic temperature compensation for reliable readings.
BNC & RCA Connectors – Compatible with Apera Instruments pH meters (e.g., PH850, PC850, PH8500, PC8500, PH700, PH910, PC910, PH950, PC950, PH800, PC800, PH820, PC820).
Highly Durable – Ideal for laboratory and industrial applications requiring highly acidic pH analysis.


Compatibility:

  BNC Connector – Works with all pH meters using BNC connections.
✔  RCA (Cinch) Temperature Sensor – May not be compatible with all non-Apera meters.


Warranty:

✔ 6-Month Manufacturer's Warranty for reliability and peace of mind.
