The Cole-Parmer Double-Junction pH Electrode is a robust, general-purpose solution for accurate pH measurement in a variety of chemical and industrial environments. Its double-junction design helps protect the AgCl reference cell from contamination by reactive substances such as heavy metals, sulfides, and organics. With a 12 mm body diameter, 100-ohm platinum Rtd for automatic temperature compensation (Atc), and a 25-ft cable with plug/BNC connectors, this electrode is well-suited for both laboratory and field applications. It performs reliably up to pH 13 and under pressures up to 150 psi at 25°C.
Product Features
- Double-junction design prevents contamination of the reference cell
- 12 mm diameter—ideal for standard lab setups and industrial processes
- 100 Ohm platinum Rtd provides automatic temperature compensation (ATC)
- Measures up to pH 13 for wide application compatibility
- Operates under pressures up to 150 psi at 25°C
- 25-ft cable with plug and Bnc connector for versatile integration
Note: 100Ω Rtd Atc elements are platinum and conform to DIN curve 43760. Atc connectors are miniature audio plugs. Connectors for the 1 kΩ Rtd and the 3 kΩ Balco Atc elements are spade lugs. Connector for 100 kΩ thermistor Atc element is not specified.
Benefits
- Reliable for use in complex or contaminated samples containing sulfides, organics, or heavy metals
- Atc functionality ensures accurate results in varying temperature conditions
- Extended 25-ft cable allows for flexible placement in hard-to-reach or remote locations
- Durable and pressure-resistant—built for challenging environments
- Easy integration with BNC-compatible meters and instruments
