AB19D1 Glass Rod Electrode
- Long-life sensor: Dual-junction design reduces reference system contamination and extends electrode lifespan.
- Measuring electrode: Thickened, low-impedance hemispherical bulb ensures high structural strength, reduced fragility, and fast response time.
- ORP electrode: High-purity platinum ring provides enhanced signal sensitivity.
- Junction: Porous Teflon external junction surrounds the pH/ORP sensitive glass bulb, offering strong anti-clogging capability.
- Reference system: High-temperature liquid gel electrolyte provides excellent pressure resistance and anti-fouling capability. The internal reference uses long diffusion path + ion trap technology to significantly reduce contamination diffusion and stabilize reference potential. The absence of Ag+ in the reference liquid prevents junction clogging in samples containing sulfides and proteins.
- Process connection: PG13.5 mounting thread with glass rod body; electrode sheath materials can be customized for different media and applications.
