pH Electrode with Built-In Temperature Sensor and DIN Connector

SKU : e955369c28a9

The HI1610D is a glass body, refillable, single junction pH electrode with a DIN connector. This electrode has a single ceramic junction in the outer reference cell and the pH sensing portion is made with general purpose glass.  This pre-amplified electrode features a built-in temperature sensor for temperature compensated measurements in a single probe design. This design consideration is ideal for laboratory and general purpose use. The HI1610D is recommended for use with Hanna’s HI8314 pH meter.

Deskripsi

 

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 HI1610D uses general-purpose (GP) glass, spherical bulb, glass body, single ceramic junction and is refillable with 3.5M KCl + AgCl.

General Purpose Glass Formulation

The measurement of pH at very high temperatures is detrimental to the sensitive glass bulb and will shorten the life of it. A pH electrode with general-purpose (GP) glass will have a resistance of 100 megaohms at 25°C while the resistance of LT glass is around 50 megaohms at 25°C. As the temperature of the glass decreases in the sample, the resistance of the LT glass will approach that of GP glass. If using GP glass, the resistance would increase above the optimum range, resulting in increased impedance and ultimately affecting the measurement. The HI1610D is suitable to use with samples that measure from 0 to 70°C.

Spherical Bulb

The spherical bulb is for general purpose use. Other tip shapes include conic for penetration and flat tip for surface measurements.

Glass Body

The glass body is ideal for laboratory use. The glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature-dependent. The faster the electrode reaches equilibrium, the steadier the reference potential.

Single Ceramic Junction

The outer junction of an electrode, also known as a salt bridge, is a necessary component of the electrical circuit. The movement of ions must flow through the junction for a steady reading. The outer reference has a single ceramic frit. The ceramic is a porous material that is easily fused with the glass body and has a similar expansion coefficient. A single ceramic junction has a flow rate of 15-20 ?L/hour. Other junction types are available with higher flow rates and made with different materials.

Refillable

The HI1610D is a refillable probe. Since it is a single junction pH electrode the fill solution is the HI7071 3.5M KCl + AgCl. If using a refillable pH electrode, the fill cap should be removed prior to calibration and measurement. Removing the cap creates positive head pressure in the reference cell allowing for a higher flow rate of electrolyte through the outer junction. A higher flow rate will result in a faster and more stable reading.

DIN Connector

The HI1610D uses a DIN connector. This type of connector is generally proprietary to the meters they are supplied with and may not be interchangeable. The HI1610D is recommended for use with Hanna’s HI8314 pH meter. Other types of connectors include BNC, screw type, T-type, and 3.5mm to name a few.
