This is 3-point pH Electrode, there is a special membrane glass & reference system that provides faster response, stable & reproducible result.

Unbreakable, (Gel filled) This probe has a flat surface and is commonly used in testing surface measurements such as cheese, meats, small liquid samples, paper, soil, skin, cloth, leather and leaves. It features a single/double-junction electrode for general-purpose applications. The junction is sealed for low maintenance use and is easy to clean.

Glass Body (KCl filled) for High temp. (0-130 0C) This is 3-point pH Electrode, there is a special membrane glass & reference system that provides faster response, stable & reproducible result.

Non Aqueous, Glass body Electrode Non-Aqueous pH Electrode, a versatile refillable, PH electrode ideal for measuring the pH of Non aqueous solutions like Oil Emulsions / Organic Solutions. Liquids can serve as solvents to dissolve solutes (i.e., solid, liquid or gaseous) to form solutions. The most common solvent is water. Solvents other than water are called non-aqueous solvents. Some examples of non-aqueous solvents are hexane, alcohol, oil, etc. It is a refillable, Single/double-junction, glass-body, combination pH electrode. The connector is BNC, compatible with any pH meter that has BNC input. The applications include testing of non-aqueous solvents, viscous solutions, and samples containing non-aqueous solvent (e.g., cosmetics, paints, etc.)

Suitable for accurate pH measurement in NMR cells Micro pH electrode is refillable with special thin glass tube sizes, suitable for small & very small volume liquid measurements.Microelectrodes are bio potential electrodes with an ultrafine tapered tip that can be inserted into individual biological cells. The volume of sample must be enough to cover the glass membrane and liquid junction of the pH electrode during measurement. Micro pH electrodes are constructed with thick glass membrane, that is highly resistant to impact and chemicals.
