Description

The Apera Instruments 201DJ-C double-junction combination pH electrode is designed for reliability in challenging liquid environments. This electrode is an excellent choice for monitoring cloudy water solutions, making it highly effective for testing wastewater, swimming pools, and spas. Its specialized construction helps ensure accuracy during environmental monitoring tasks where traditional electrodes might struggle. Built with a double connection point, this electrode prevents clogging and contamination during use. This design feature extends the life of the sensor when working with complex or debris-heavy samples. The durable polycarbonate casing provides a sturdy build for professional and industrial applications. This BNC connection electrode is compatible with various pH meters for consistent liquid analysis. Please note that this model is not intended for use in low ion concentration solutions like distilled or deionised water, nor is it suitable for strong alkaline solutions (pH >12), strong corrosive liquids, or long-term measurements in high temperature solutions exceeding 60 degrees Celsius.

Key Features

Double Junction Design: The specialized double connection point prevents the electrode from being clogged or contaminated, making it ideal for cloudy water solutions.

Versatile Application: Optimized for testing wastewater, swimming pools, spas, and general environmental monitoring tasks.

Wide Measurement Range: Provides reliable pH readings across a full scale of 0-14 pH and a temperature range of 0-80 degrees Celsius.

Durable Construction: Features a robust polycarbonate casing and a ceramic diaphragm for long-lasting performance in liquid analysis.

Standard BNC Connection: Equipped with a BNC connector for easy integration and compatibility with various pH meter systems.

Ag/AgCl Reference: Utilizes a silver/silver chloride reference electrode to maintain measurement stability.
