Product information "JUMO tecLine pH electrode with salt reserve (UW glass, PTFE ring diaphragm, S8 screw head Pg13.5, 120mm)"
Thanks to the salt reservoir, this version is particularly suitable for applications with low-ion media or higher flow rates, where an extended electrode service life is beneficial.
JUMO tecLine pH electrode with salt reservoir, UW glass, PTFE ring diaphragm, S8 Pg13.5 screw head, 120 mm (Type code: 201020/51-18-04-22-120/837; Part No.: 321035)
This JUMO tecLine pH electrode is a good choice when a reliable and durable solution for pH measurement in aqueous media is required. With its salt reservoir design, this version is especially suitable for applications where the electrode is used under more demanding conditions and where maximum service life is required. Users looking for more than a standard pH electrode will benefit from a design focused on stable and long-term operation.
Advantages and special features
A key advantage of this electrode lies in the combination of UW glass, PTFE ring diaphragm, and salt reservoir. The UW glass supports reliable pH measurement, while the PTFE ring diaphragm provides a robust solution for more demanding measurement conditions. The salt reservoir is particularly beneficial in applications where higher requirements are placed on electrode lifetime. This makes the design especially attractive for users who value a robust and long-lasting electrode for regular measurement tasks.
Technical information
With the S8 Pg13.5 screw head and a 120 mm insertion length, the electrode is suitable for many common installation situations. The glass shaft design makes it a classic solution for precise pH measurements in appropriate applications. Its well-balanced construction allows easy integration into existing measurement setups.
Why choose this electrode?
Because it is particularly suitable when a pH electrode is not only required to measure reliably but also to maintain long-term stability and durability in continuous operation. The salt reservoir makes this electrode especially attractive for conditions where extended service life is important. Combined with the PTFE ring diaphragm, it results in a robust and high-quality solution for users requiring dependable routine measurements.
Applications
The electrode is used for pH measurement in aqueous media. It is suitable wherever precise pH monitoring is required and where a salt reservoir provides additional benefit. This makes it a strong choice for applications where reliability, service life, and clean integration into the measurement point are important.
