Solve the problem of contaminated junctions with this polymer-filled electrode with Ag/AgCl reference isolated by a Xerolyte® solid electrolyte sample interface. Contamination, mainly by fats and proteins, causes sluggish,unstable readings and a slope loss. Designed for use with heavily contaminated solutions; emulsions and suspensions; effluent waters; and media containing protein. Using an open port, instead of the conventional ceramic junction between the sample and the reference electrolyte, substantially reduces the risk of clogging. Non-refillable. Requires BNC/S7 adapter cable which is sold separately.
