Hanna Instruments FC213D pH Electrode for Yogurt Analysis

The FC213D pH electrode with internal temperature sensor is specifically designed for yogurt analysis and for use with the old style HI-99164 pH meter (please check your model before purchasing).

This electrode is for the old style HI-99164. Please check your model before purchasing. (New models will need the FC2133).

The old model looks like this:

Key Features

• Glass body
• Built-in temperature sensor
• Conical glass tip

Glass body

• The glass body of the FC213D allows standards and samples to reach thermal equilibrium quickly whilst also providing chemical resistance.

Viscolene electrolyte

• The viscolene electrolyte offers a hard gel interface between the inner electrode components and the sample being measured. The electrolyte is silver-free for use in yogurt and is maintenance free too.

Conical tip shape

• The design allows for penetration into semi-solids and emulsions for the direct measurement of pH in yogurt products.

Open junction reference

• Clogging of the reference junction is a common challenge faced by yogurt producers as the milk solids and proteins can easily build up on the electrode. The open junction design of the FC213D resists clogging and continues to provide accurate, stable readings.

Built-in temperature sensor

• A thermistor temperature sensor is in the tip of the indicating pH bulb. A temperature sensor should be as close as possible to the indicating pH bulb in order to compensate for variations in temperature.

Low temperature glass

• The FC213D electrode uses Low Temperature (LT) glass for the sensing bulb. The LT glass tip is a lower resistance glass formulation. As the temperature of the sensing glass decreases, the resistance of the LT glass will increase approaching that of standard glass at ambient temperatures. The FC213D is suitable to use with samples that measure from 0 to 50°C.
