  • Acidic Error: Less than 0.05 pH in 1.0 M HCl @ 0.00 pH
  • Reference System Specifications:
  • Type: Triple Junction
  • Reference Half Cell: Ag/AgCl, Saturated KCl
  • Primary Junction: Porous Ceramic, Sulfide resistant crosslinked polymer
  • Secondary Junction: Porous Kynar, Sulfide resistant crosslinked polymer
  • Surface Area: 366,000 mil2 (236 mm2)

Special Features:

Sulfide resistant crosslinked polymer is resistant to heat, solvents and to most chemicals. It also slows the diffusion of sulfide ions and traps them before reaching the reference half cell. Sensor holds an excess of a salt mixture, assuring saturation at all temperatures and extending in situ sensor life. The reference system holds a generous supply of aqueous saturated salt mixture, eliminating effects of intruding contaminants and permits the sensor to be left in dry condition for extended periods of time.

Recommended Applications:

  • Wastewater treatment, chemical processes, pollution control, refinery water, management and treatment, oil drilling, measurements where long service life or operation at remote locations where (no) low maintenance is required.
  • Abrasive slurries, high viscosity stock in food, paper, paper pulp and mining industries.
  • Fluoride containing wastewater, etching solutions, pollution control devices, where long service life or operation at remote locations where (no) low maintenance is required.

Storage and Shelf Life: At room temperature with closed protector cap, 1 year from date of manufacture.

Standard Hook-Up Options: With Preamp - Multiconductor Lead Wires
