HI1286 provides pH testing capabilities to any user at an affordable price. The polyetherimide (PEI) body protects against accidental breakage, while the spherical glass is ideal for aqueous samples due to its large surface area. Suitable for samples from 0 to 80°C, this electrode is well suited for routine applications.

PEI Polyetherimide Body

The body of the HI1286 is made of polyetherimide (PEI) resin. The PEI body is suitable for a wide range of applications and performs well in field measurements due to its durability. The shield around the spherical glass reduces breakage caused by accidental impact or dropping of the electrode. PEI plastic is a high-quality plastic with chemical resistance to many corrosive chemicals.

PTFE Polytetrafluoroethylene Junction

Porous polytetrafluoroethylene (PTFE) is a hydrophobic material with varying porosity. This type of junction is commonly used on electrodes with polymer electrolytes. Due to its chemical advantages, PTFE is widely used in industrial applications.

Double Junction Electrode

A double junction electrode has an inner compartment around the reference wire. Silver ions are present in the electrolyte of the inner 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 measurements in applications where silver ions in the sample are undesirable or may form silver precipitates at the junction.

BNC Connection

The HI1286 uses a BNC connection. This type of connector is universal, as it can be used on any pH meter with a female BNC probe input. Other types of connectors include DIN, screw-type, T-type, and 3.5 mm, etc. These types of connectors tend to be proprietary to specific types of meters and are not interchangeable.
