Product information "JUMO tecLine PRO pH electrode (process electrode, UW glass, annular gap diaphragm, screw head Pg13.5, salt reserve)"

Anyone looking for a pH electrode for process applications and placing value on UW glass, annular gap diaphragm, screw head Pg13.5, salt reservoir, and an especially robust design will make a solid choice with this JUMO tecLine PRO variant.

JUMO tecLine PRO pH electrode as process electrode with UW glass, annular gap diaphragm, screw head Pg13.5 and salt reservoir

This JUMO pH electrode is designed for demanding pH measurements in process applications. It is particularly suitable for areas where high mechanical and chemical resistance is required. As a process electrode with UW glass, open annular gap diaphragm, screw head Pg13.5, and salt reservoir, this version is designed for robust operating conditions and is significantly more durable than sensitive standard sensors.

Advantages and Features

A key advantage of this version is its robust construction. According to your description, the electrode features a stable PVDF body, which effectively eliminates the risk of breakage of the sensor. In industrial applications, this is an important factor when the measuring point must not only provide reliable pH values but also withstand mechanical stress in everyday operation.

At the same time, the electrolyte of this combination electrode ensures stable measurement signals even in critical sulfite-containing media. This makes the electrode particularly suitable for applications where other designs may reach their limits more quickly.

Why choose this electrode?

This version is especially suitable when a robust process electrode is required for demanding media and industrial environments. The UW glass is designed for process applications, while the open annular gap diaphragm provides advantages in applications requiring a durable and process-compatible design.

The additional salt reservoir can extend service life and is beneficial when long-term stability at the measuring point is required. This makes the electrode particularly attractive for users seeking a reliable and durable solution for pH measurement.

The connection side is also designed for professional use. The screw head Pg13.5 enables compatible integration into suitable measurement systems. According to your description, a Pt1000 temperature sensor is also integrated. This is especially useful when temperature must be measured directly at the process point, for example for temperature compensation or additional process monitoring.

Typical Applications

  • Chemical industry
  • Wastewater treatment
  • Wastewater treatment plants
  • Pulp and paper industry

Wherever a durable process electrode with stable measurement performance and a robust design is required, this version is particularly suitable. It can demonstrate its strengths especially in demanding industrial environments.
