Description

Dual junctions provide fast response and long life in paper pulp testing

• Perfect for paper pulp testing, mine assay labs, smelters—anywhere junction clogging may be a problem
• Inner chamber houses reference element with gelled KCl and AgCl; the outer chamber contains KCl only
• Eliminates heavy metal ions that react with sulfide ions in samples such as black and green liquors
• No insoluble sulfide precipitates to block electrode junction and cause premature failure
• Polypropylene body
• Fisher Scientific universal glass membrane for rapid, reproducible response
• Glass tip is recessed in end

Fast and accurate

• Accuracy, ±0.05pH at 25°C (77°F) Efficiency, >95% Sodium Ion error, <±0.05pH at 25°C (77°F) Response time, 30 seconds Zero potential, 7.0 ±0.3pH
• Membrane resistance, <100megohms at 25°C (77°F)

• Ideal for routine process monitoring in paper pulp plants, mine assay labs, smelters
• Fits any application where the presence of S⁼ in samples causes problems of slow response and junction failure
