pH Electrode for Continuous Monitoring with DIN Connector – HI1611D

The HI1611D is a glass body, 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 high temperature 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 measurements that require continuous monitoring. The HI1611D is recommended for use with Hanna’s HI8314 pH meter.

SKU:HI1611D

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 HI1611D uses high temperature (HT) glass, spherical bulb, glass body, single ceramic junction and gel electrolyte.

Glass

High Temperature 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℃ while the resistance of HT glass is around 400 megaohms at 25℃. As the HI1611D is used at elevated temperatures the resistance decreases to approach the that of GP glass. The HI1611D is suitable to use with samples that measure from 0 to 80℃.

Flat Tip

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

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.

Open Junction

Single Ceramic Junction

The outer junction of an electrode, also known as a salt bridge, is 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 μL/hour. Other junction types are available with higher flow rates and made with different materials.

DIN connector

DIN Connector

The HI1611D uses a DIN connector. This type of connector is generally proprietary to the meters they are supplied with and may not be interchangeable. The HI1611D is recommended for use with Hanna’s HI8314 pH meter. Other type of connectors include BNC, screw type, T-type, and 3.5mm to name a few.

HI7061L General Purpose Cleaning Solution (500 mL)

61.00 AED
HI7061L is a general purpose cleaning solution that can be used for a variety of applications. Electrodes can become dirty from use and will produce inaccurate results even as they read correctly in a pH buffer. Hanna’s cleaning solutions eliminate impurities and residues that are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly. Hanna suggests cleaning the bulb and junction of your electrode on a regular basis to ensure that the probe is always clean and to prevent any clogging of the junction.
  • Specially formulated for cleaning electrodes
  • Air tight seal to ensure quality
  • Expiration date and lot number

HI70300L Electrode Storage Solution (500 mL)

59.00 AED
HI70300L is a storage solution prepared with reagent grade chemicals that can be used to ensure optimum performance of your pH and ORP electrodes. It is necessary to store a pH electrode in a solution in order to keep the glass membrane of the pH electrode hydrated. Ideally a storage solution should be used; never store an electrode in distilled or deionized water. The Hanna Instruments storage solution is specifically formulated to minimize microbial growth and to prevent any effects of diffusion/osmotic from storing a probe in a solution with the highly concentrated inner reference electrolyte. Storing your pH and/or ORP electrodes in a storage solution will also keep the junction clear. Maintaining the hydrated layer and clear junction will help to ensure a fast and reliable measurement. In the case of cleaning your pH electrode in one of our cleaning solutions, we recommend soaking the electrode in the HI70300L storage solution for at least one hour before taking measurements.
  • Special formulation to minimize microbial growth and osmotic/diffusion effects between the solution and inner reference electrolyte
  • Manufactured specifically for pH and ORP electrodes
  • Clearly marked expiration date and lot number
