PH8500-HT pH Meter for High Temp. Liquid

Apera Instruments, AI5566, PH8500-HT Portable pH Meter for High Temperature Liquid and Caustic SolutionsFeatures:Equipped with Swiss LabSen 861 pH Electrode for high-temp liquid and caustic solutionsGLP standard data management, 500 data sets of storage, manual/auto storage, USB data outputLarge backlit LCD DisplayIntelligent Functions: Self-Diagnosis of out-of-range value and electrode invalidationAuto calibrationElectrode slope displayAuto power-offEasy parameter settingRugged Structure Design: IP57 waterproof rating; Soft silicone case gives you a firm and comfortable gripPowered by AA batteriesLabSen 861Powered by sensor technologies and key materials from Switzerland, LabSen 861 pH Electrode, which is built with LabSen's most robust PHY glass membrane and anti-clogging PTFE junction along with a Silver-ion-trap reference system, making reliable pH measurement of high-temperature liquid and caustic solutions easier than ever. he special PHY membrane is highly resistant to chemical corrosions, maximizing the reliability and service life of the electrode in complex and high-temp. solution testing. The PTFE ring junction prevents junction clogs from complex chemicals.Silver-ion-trap reference systemThe combination of a Long-life reference system and a silver ion trap. The silver ion trap will absorb all the exuded Ag+, ensuring that there's no Ag+ in the reference electrolyte, and avoiding junction clogs caused by samples containing sulfides, proteins or TRIS buffer solutions.
