Hanna Instruments HI1286 Economy PEI Plastic Body pH Electrode

Durable General-Purpose pH Electrode • PTFE Junction • Double Junction Design • Universal BNC Connector

The Hanna Instruments HI1286 is a reliable, budget-friendly general-purpose pH electrode engineered for everyday testing in laboratories, fieldwork, and hydroponic nutrient solutions. Designed with a rugged polyetherimide (PEI) plastic body, this electrode offers excellent resistance to breakage and chemical exposure—making it an ideal choice for users who need dependable pH measurements without premium cost.

Featuring a spherical glass tip for strong signal stability in aqueous samples, a PTFE junction to resist clogging, and a double junction reference to protect sample integrity, the HI1286 delivers consistent performance across a wide range of general applications.

Why Choose the HI1286 pH Electrode?

✔ Durable PEI Body for Field & Lab Use

The PEI plastic body is tough, lightweight, and chemically resistant. It shields the glass bulb from accidental bumps and drops—ideal for routine testing and mobile use.

✔ Spherical Glass Tip for Aqueous Samples

A 7.5 mm spherical glass bulb provides a large surface area, improving measurement stability and repeatability in water-based solutions.

✔ PTFE Junction Resists Clogging

The hydrophobic PTFE junction helps prevent blockage from particulates and proteins, maintaining steady electrolyte flow and extending electrode life—especially useful in nutrient solutions and industrial environments.

✔ Double Junction Reference for Cleaner Measurements

The double junction design isolates silver ions within the internal reference chamber, reducing contamination of the sample and minimizing junction fouling. This makes the electrode suitable for samples where silver contamination is undesirable.

✔ Universal BNC Connector

Equipped with a standard BNC connector, the HI1286 is compatible with most pH meters that accept BNC probes—making it an easy replacement or upgrade without proprietary fittings.
