New electrodes from Hanna Instruments have been added.

Introduction
Hanna Instruments HI-11310 electrode from Wolflabs. The HI11310 is a glass body refillable double junction pH electrode with a built-in temperature sensor for temperature compensated measurements in a single probe design. This probe connects to the meter with a 3.5 mm connector. The 3.5 mm connector is proprietary to meters that use digital electrodes.

Features and benefits
- The built-in microchip stores sensor type, serial number and calibration information including date, time, offset, slope, probe condition and buffers used.
- The spherical shaped tip design allows for a wide area of contact with the sample.
- A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. 
- The glass electrode body is suitable for a wide range of applications due to its chemical resistance. 
- HI11310 features a built-in thermistor temperature sensor that is in the tip of the indicating pH electrode. A thermistor temperature sensor provides for a high accuracy temperature reading and should be as close as possible to the indicating pH electrode in order to compensate for the effect that temperature has on the membrane potential. 

Introduction
Hanna Instruments HI-1230B electrode from Wolflabs. The HI-1230B is a PEI body, double junction pH electrode with a BNC connector. This electrode has a single ceramic junction in the outer reference cell and the spherical pH sensing portion is made with general purpose glass and is protected by an extension of the durable PEI body.

Features and benefits
- General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25°C and is suited for measuring pH of samples that are at ambient temperatures. The HI-1230B is suitable to use with samples that measure from 0 to 70°C.
- The spherical bulb is for general purpose use. Other tip shapes include conic for penetration and flat tip for surface measurements.
- The body of the HI-1230B is composed of polyetherimide (PEI) resin. The PEI body is suitable for a wide range of applications and excels in field measurements due to its durability. The shielding around the spherical glass tip minimizes breakage due to accidental bumping or dropping of the electrode. The PEI plastic is a high quality plastic that is chemically resistant to many aggressive chemicals.
- A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or silver precipitates on the junction are likely to form.
- The HI-1230B uses a BNC connector. This type of connector is universal in that it can be used on any pH meter that has the female BNC probe input. 

Introduction
Hanna Instruments HI-12300 electrode from Wolflabs. The HI-12300 is a smart pH electrode for use with the HI-2020 Edge hybrid meter.

Features and benefits
- This electrode features a built-in microchip that stores sensor type, ID, and calibration information that is automatically retrieved by Edge once the electrode is plugged in.
- Stored pH calibration information includes: calibrated buffers, date, time, offset and slope characteristics of the electrode.
- The HI-12300 features an easy to plug in 3.5mm connector and is recommended for use in field applications.

Introduction
Hanna Instruments FC200B electrode from Wolflabs. 

Features and benefits
- The FC200B electrode is recommended for use with dairy products such as milk, yogurt and soft cheese in addition to other semi-solid food stuffs.
- The main body of the electrode is covered in white Kynar (a type of PTFE) which is both easy to clean and food safe.
- This electrode is ideal for semi solid food applications, milk, yogurt, dairy products.
- 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.
