pH Electrode Double-Junction Apera Instruments 201DJ-C with BNC

Description

Product Overview

The Apera 201DJ-C double-junction pH electrode is engineered for precision and durability in demanding analytical environments. Its robust PC housing protects the sensitive glass membrane while providing a lightweight form factor that is easy to handle during routine measurements. The double-junction design creates a physical barrier that prevents clogging from particulate matter, making it especially suitable for turbid or slurry samples where single-junction electrodes often fail. The electrode is pre-filled with a stable gel KCl electrolyte, eliminating the need for periodic refilling and reducing maintenance downtime. A standard BNC connector ensures reliable signal transmission to most laboratory meters and data acquisition systems, while the included 3 ft cable offers flexibility without compromising signal integrity. Detailed specifications include a compact size of 6.3 x 0.5 x 0.5 inches, a weight of 3.84 ounces, and a model number AI3115, reflecting Apera’s commitment to high‑quality instrumentation.

Usage

This electrode excels in a wide range of applications, from quality control labs monitoring beverage acidity to field technicians testing water sources in environmental surveys. Its clog‑resistant double‑junction architecture allows accurate pH readings in cloudy or particulate‑laden liquids such as fermentation broths, wastewater, and mineral processing streams. The durable construction withstands routine cleaning procedures, including gentle rinsing with distilled water, without compromising the integrity of the glass membrane. Users can connect the electrode directly to standard pH meters equipped with BNC inputs, making it compatible with both handheld devices and benchtop analyzers. The 3 ft cable provides sufficient reach for samples housed in large tanks or reactors, reducing the need for additional extension leads that could introduce signal noise. Whether deployed in a controlled laboratory setting or a rugged field environment, the 201DJ-C delivers consistent performance, helping professionals maintain compliance with regulatory standards and achieve reliable data for decision‑making.

FAQ

What is a double‑junction pH electrode and why is it beneficial?

A double‑junction electrode contains two separate junctions between the internal reference solution and the sample. This configuration creates an additional barrier that blocks particles and contaminants from reaching the sensitive glass membrane, which greatly reduces the risk of clogging and extends the electrode’s usable life, especially in dirty or cloudy liquids.

Do I need to refill the electrolyte solution?

No. The 201DJ-C comes pre‑filled with a stable gel‑filled KCl electrolyte that is sealed within the electrode. This design eliminates the need for periodic refilling, saving time and preventing potential errors associated with manual electrolyte replacement.

Is the BNC connector compatible with my existing pH meter?

The BNC connector used on this electrode follows the standard 50 Ω configuration common to most laboratory pH meters and data acquisition systems. As long as your instrument accepts a BNC input, you can connect the electrode directly without additional adapters.

Can this electrode be used for field measurements?

Yes. The robust PC housing, clog‑resistant double‑junction design, and 3 ft cable make the 201DJ-C well‑suited for on‑site testing of water, soil leachate, and industrial process streams where portability and reliability are essential.

What warranty or support does Apera provide?

Apera Instruments offers a six‑month fulfillment guarantee for the 201DJ-C. During this period, customers receive technical assistance, troubleshooting help, and access to replacement parts if the electrode experiences any issues related to manufacturing defects.
