bids are invited for ph electrode model 615. make : ic controls. - ph electrode model 615. make : ic controls. high purity water electrode contructed from cpvc material body fits inside a 615 ss flow cell housing comes with 1.8 meter (6ft.) double shielded cable 0 ph to 14 ph. maximum pressure 690kpa (100 psi), maximum temperature 100c. (212 f). the ph electrode is completely shielded in the stainless steel flow body. reference is plastic with porus plastic annular junction surrounding the ph glass ensuring stable ionic connection. sample entering directly at the ph tip ensures fast response and no drift from ph shifts induced by kci salt dissociation as concentration changes with sample flow. small ph tip design also passes entrained air and co2 bubbles. recommended for new installations below 1 s/cm, option-21,-24 and -26. below 15 s/cm, option -21, -24 and-25 , high purity water ph analyse - high purity water ph analyser of ic control make no.655. total quantity : 1
