Special Features:

Crosslinked polymer is resistant to heat, solvents and to most chemicals. Sensor holds an excess of KCl, assuring saturation at all temperatures and extending in situ sensor life. The referencesystem holds a generous supply of aqueous saturated KCl, eliminating effects of intruding contaminants and permits the sensor to be left in dry condition for extended periods of time. Reference junction material and crosslinked polymer is abrasion resistant. The special configuration and low profile of the active sensor surface does not interfere with the process flow and insures long product life.

Recommended Applications:

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: No Preamp - Signal + TC lead wires
