Product Overview:
The Eutech ECFC7252101B is a general-purpose plastic-body combination pH electrode designed specifically for routine measurement applications. This electrode is engineered for convenience and durability, making it suitable for a wide variety of general laboratory and field uses. The design incorporates a sealed, gel-filled reference cell, ensuring minimal maintenance is required. The inclusion of a recessed glass pH bulb provides added protection against physical damage.
Construction and Durability:
This electrode is constructed using specialty engineering plastic for the shaft material, which provides high impact resistance. This housing is robust enough to withstand the rigours of rugged use and can operate at pressures up to 3 bar and temperatures up to 80 °C. The plastic body improves overall electrode durability.
The electrode uses X-1 membrane glass. This type of glass is best suited for low temperature applications, nonaqueous solutions, and pH measurements that stay below pH 12. The shape of the pH membrane is spherical
Reference System and Junction:
The ECFC7252101B utilises a single junction reference system. Single junction electrodes are generally ideal for standard, general-purpose applications.
The reference type is Silver/Silver Chloride (Ag/AgCl) sealed. Sealed, gel-filled reference electrodes are chosen for convenience as they require virtually no maintenance.
The liquid junction type employed is the Porous High-Density Polyethylene (HDPE) Pin. Plastic body combination electrodes typically come standard with this type of junction. The Porous HDPE Pin junction offers low electrolyte flow, enhancing the overall durability of the electrode.
Key Applications:
The design and specifications of the ECFC7252101B make it highly versatile for several application types, including:
• General Use: Ideal for aqueous pH measurements, quality control checks, general laboratory environments, and monitoring aquarium water.
• Portable/Field Use: Excellent for use with portable pH meters, suitable for field measurements, and school educational settings.
• Continuous Flow: Suitable for swimming pool pH control applications where continuous flow conditions are present.
