Extech EC505 Replacement pH Electrode & Conductivity Cell Module

The Extech EC505 is a dedicated replacement module designed for the Extech EC500 Waterproof ExStik II pH/Conductivity Meter. This essential spare part restores the full analytical capabilities of your meter, allowing for precise measurement of key water quality parameters.

Engineered for durability, it features a rugged, flat-surface design that is easy to clean, ensuring consistent performance and minimal maintenance in demanding field or lab conditions. The integrated module simultaneously measures conductivity, Total Dissolved Solids (TDS), salinity, pH, and temperature, providing a comprehensive snapshot of your sample's characteristics.

Key Features & Specifications

• Multi-Parameter Measurement: Capable of reading conductivity, TDS, salinity, pH, and temperature from a single probe.
• Robust Flat-Surface Design: The easy-to-clean, rugged construction resists damage and fouling, ideal for frequent use.
• Automatic Temperature Compensation (ATC): Incorporates a built-in Pt-100Ω sensor to ensure highly accurate readings by automatically compensating for temperature variations.
• Specific Compatibility: This module is non-interchangeable and is designed exclusively for use with the ExStik II pH/Conductivity Meter (model EC500). It will not function with standard ExStik pH, chlorine, or ORP meters.
• Complete Protection: Supplied with a protective connector cap to safeguard the sensitive electrical contacts when the module is not in use, extending its operational life.

With compact dimensions and a lightweight build, the EC505 module is a practical and reliable solution for professionals in environmental monitoring, aquaculture, hydroponics, education, and industrial process control who depend on their ExStik II meter for accurate, on-the-spot water analysis.
