Fisherbrand™ accumet™ Gel-Filled Paper Pulp Double-Junction pH Combination Electrodes: Mercury-Free 
Dual junctions provide fast response and long life in paper pulp testing
Supplier: Fisherbrand™ 13620299A
Catalog No. 13-620-299A
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
- 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
