HI1413S/50 is a glass body, single reference junction, pH electrode made of low temperature glass and screw connector. This electrode features a unique open junction design with a silver chloride (AgCl)-free viscosity (hard gel) electrolyte layer between the sample to be measured and the internal reference cell. The open junction design prevents clogging, and the flat shape of the probe makes it ideal for pH measurement on surfaces such as skin, leather, agar plates, and paper.

Low Temperature Glass Formulation

Low temperature glass membranes have lower impedance and are suitable for samples with lower temperatures and lower conductivity. We select quality components for glass membrane sensors to ensure accurate and quality measurements. Since many foods are stored at low temperatures, the HI1413S/50 is suitable for samples at temperatures from 0 to 50°C.

Flat Glass Tip

The flat profile allows direct measurement of the sample surface and is recommended for optimizing surface contact for measurements on skin, leather, agar plates, paper, and samples that are difficult to penetrate.

Glass Body

The glass body is ideal for laboratory use. The glass resists many harsh chemicals and is easy to clean. The glass body also allows heat to be transferred quickly to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The faster the electrode reaches equilibrium, the more stable the reference potential.

Open Junction Reference

The open junction design consists of a solid gel interface (viscosity agent) between the sample and the internal Ag/AgCl reference. This interface not only prevents silver from entering the sample, but also makes it less prone to clogging, resulting in fast response and stable readings.

DIN Connector

The HI14143/50 uses a quick-connect DIN connector. This type of connector is made for Hanna meters that accept quick-connect DIN connectors. The HI14143/50 is recommended for the HI99181 pH meter. Other types of connectors include BNC, screw type, T type, and 3.5mm, etc.
