Economy PEI Plastic Body pH Electrode - HI1286

SKU: HI1286

Ships within 1-2 Business Days

The HI1286 brings the ability to test pH to any user at an affordable price. The polyetherimide (PEI) body protects against accidental breakage while the spherical glass tip is perfect for aqueous samples due to the large surface area. Suitable for samples from 0 to 80°C (32 to 176°F), this electrode is perfect for any general use application.

  • PEI body offers increased durability
  • PTFE junction protects against clogging
  • Universal BNC connector makes this the perfect replacement electrode

PEI Body

The body of the HI1286 is composed of polyetherimide (PEI) resin. The PEI body is suitable for a wide range of applications and excels in field measurements due to its durability. The shielding around the spherical glass tip minimizes breakage due to accidental bumping or dropping of the electrode. The PEI plastic is a high quality plastic that is chemically resistant to many aggressive chemicals.

PTFE Junction

Porous polytetrafluoroethylene (PTFE) is a hydrophobic material that is available with different porosities. This type of junction is often used on electrodes with polymer electrolytes. Because of its chemical advantages, PTFE is widely used in industrial applications.

Double Junction Reference

A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or silver precipitates on the junction are likely to form.

BNC Connector

The HI1286 uses a BNC connector. This type of connector is universal in that it can be used on any pH meter that has the female BNC probe input. Other type of connectors include DIN, screw type, T-type, and 3.5mm to name a few. These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable.
