Digital Flat Tip pH Electrode for Food Surfaces
The HI14140 has a unique open junction design that resists clogging and the probe’s flat tip makes it ideal for pH measurements on food surfaces. This probe features a 3.5 mm connector designed exclusively to be used with Hanna Instruments edge® Tablet Meters.
• Built-in temperature sensor for automatic compensation of measurements.
• Ideal for surface measurements of meat and food samples.
• Open junction design resists clogging.
The HI1414D uses low temperature (LT) glass, flat tip bulb, glass body, and open junction with viscolene gel electrolyte.
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°C.
• 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.
Flat Glass Tip
• A flat tip is recommended to optimize surface contact for measurement on skin, leather, agar plates, paper, and samples that cannot easily be penetrated.
• Additionally, the recessed flat tip is easy to clean and prevents food solids from collecting on the sensor.
• 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 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 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.
