AS200 Molded Case 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 a large surface area and strong anti-clogging capability.
- Reference system: High-temperature solid gel electrolyte provides excellent pressure resistance, anti-fouling capability, and permeability. 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.
- Temperature system: Temperature electrode housed in an independent glass tube ensures accurate and fast temperature measurement.
- Chemical resistance: Thickened and robust PPS (polyphenylene sulfide) material provides excellent corrosion resistance.
- Process connection: 3/4” NPT connections on both ends for versatile installation needs.
