Digital pH/temperature flat tip electrode for surface measurement - HI14140

$398.43


Prices include GST. Not all items are in stock. Call 03 9769 0666 to confirm.

The HI14140 has a unique open junction design that resists clogging and the probe’s flat tip makes it ideal for pH measurements of skin, paper, food and various surfaces. This probe features a 3.5 mm connector designed exclusively to be used with Hanna Instruments “edge” series pH meters

  • Flat Tip for Surface Measurements
  • Built-In Temperature Sensor
  • 3.5 mm Connector

Description

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 HI14140 uses low temperature (LT) glass, flat tip bulb, glass body, and open junction with viscolene gel electrolyte.

Built-In Microchip HI14140

Built-In Microchip

The built-in microchip stores sensor type, serial number and calibration information including date, time, offset, slope, probe condition and buffers used. This information is automatically retrieved by edge® once the electrode is plugged in. The ability to transfer information allows for hot swapping of probes without having to recalibrate. All pH measurements are performed within the electrode and transferred digitally to the meter.

Low Temperature Glass Formulation

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. The HI14140 is suitable to use with samples that measure from 0 to 50℃.

flat tip

Flat Tip

A flat tip is recommended to optimize surface contact for measurement on food products and samples that cannot easily be penetrate. Additionally, the recessed flat tip is easy to clean and prevents food solids from collecting on the sensor.

 

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

Open Junction Reference

Suspended solids and proteins found in food products will clog a conventional ceramic reference junction. This clogging will impede the measurement circuit between the indicating electrode and the internal reference resulting in slower response time, erratic readings, and frequent electrode replacement. 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 food measurements.

 

digital electrode 3.5 mm connector

 

Digital 3.5 mm Connector

Plugging an electrode in has never been simpler; no alignments or broken pins, simply connect the 3.5 mm plug and begin. Digital electrodes are automatically recognized.
