Apera LabSen 333 POM-Body pH/Temperature Electrode

Apera LabSen 333 POM-Body pH/Temperature Electrode

Product Overview

The Apera LabSen 333 POM-Body pH/Temperature Electrode is a specialized professional electrode designed for accurate pH measurement in challenging samples such as wastewater, emulsions, suspensions, and other complex solutions that can easily clog conventional pH electrode junctions.

Featuring an open junction and polymer electrolyte, the LabSen 333 provides direct contact with the sample while significantly reducing the risk of junction clogging. Its durable POM body offers excellent corrosion resistance, making it suitable for harsh laboratory, industrial, and environmental applications.

The integrated 30KΩ NTC temperature sensor enables simultaneous temperature measurement and Automatic Temperature Compensation (ATC).

Reference System

The LabSen 333 incorporates a Long-Life Reference System consisting of a glass tube, AgCl, and reference silver wire. Its design helps prevent unwanted reactions between AgCl and the electrolyte caused by temperature changes, improving reference stability and extending the electrode’s operational life.

Open Junction & Polymer Electrolyte

The open junction provides direct contact between the reference system and the test sample, helping minimize clogging when measuring samples containing suspended solids, emulsions, or other contaminants. The polymer electrolyte eliminates the need for electrolyte refilling, simplifying maintenance and improving convenience during routine use.

Compatibility

The LabSen 333 is compatible with Apera Instruments meters equipped with BNC and RCA connections, including:

• Apera PH910
• Apera PH950
• Apera PH850
• Apera PC850
• Other compatible Apera instruments with BNC/RCA inputs

Compatibility with meters from other brands may vary because the integrated temperature sensor uses a specific thermistor configuration.

Applications

• Wastewater testing
• Environmental water analysis
• Industrial wastewater monitoring
• Emulsion testing
• Suspension analysis
• Chemical processing
• Industrial process control
