The HI1413B/50 is a glass-body, single-reference junction, pH electrode made with low temperature glass and a BNC connector. The electrodes design resists clogging while the probe's flat tip is ideal for pH measurements on flat surfaces such as skin, leather, and paper.

Open Junction

Flat Tip

Viscolene Gel Electrolyte

Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.

The HI1413B uses low temperature (LT) glass, flat tip bulb, glass body, and open junction with viscolene gel electrolyte.

Glass

Low Temperature Glass Formulation

The glass tip uses a special LT glass formulation with a lower resistance of approximately 50 megaohms compared to general purpose (GP) with a resistance of about 100 megaohms. This is beneficial since many food products are stored at low temperatures. As the temperature of the glass decreases in the sample, the resistance of the LT glass will increase approaching that of GP glass at ambient temperatures. If using GP glass, the resistance would increase above the optimum resistance for the high impedance input of a pH meter.The HI1413B is suitable to use with samples that measure from 0 to 50°C.

Flat Tip

Flat Glass Tip

A flat tip profile allows direct surface measurement of a sample and optimizes surface contact for measurement on skin, leather, agar plates, paper, and samples that cannot easily be penetrated..

glass Body 

Glass Body

The glass body is as staple of pH electrode design and ideal for laboratory use. The glass is resistant to many harsh chemicals, is easy to clean, and transfers heat readily for fast thermal equilibrium between the sample and the sensor. The mV generated by the reference cell is temperature-dependent. The faster the electrode reaches equilibrium, the steadier the reference potential..

 

Open Junction

Open Junction Reference

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

bnc connector

 BNC Connector

The HI1413B/50 uses a BNC connector. This type of connector is universal and can be used on any pH meter that has the female BNC probe input..
