pH SENSOR Rosemount Analytical, Liquid Div. www.raihome.com Rosemount Analytical TUpH sensors incorporate the patented TUpH reference junction technology and helical pathway combined with AccuGlass to perform exceptionally well in harsh, dirty, high-solid applications with minimal maintenance. TUpH sensors include SILCORE technology triple-seal contaminant barrier that prevents moisture and material impurities from migrating to the pH electrode’s metal lead wire, resulting in increased sensor life. The tech- nology also protects against sensor failure due to vibration by transferring damaging energy away from the glass-to- metal seal. Circle 153 on reader information card
