AI3180 LabSen 853-H Glass-body pH/Temp. Electrode for Highly Viscous Solutions with High Alkalinity/temperature by Apera

LabSen 853-H pH/temp. electrode is designed for high-accuracy pH measurement of highly viscous liquid samples such as skin care products, coatings, syrups, resin, glue, etc. as well as general water solutions.

The pre-pressurized structure allows the electrolyte to stably flow out even in highly viscous samples, eliminating the chance of a clogged junction.

The robust HA glass membrane minimizes alkaline error in high salinity or strong alkaline solutions and withstand temperature up to 100°C.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera MP500) to enable ATC or manually input temperature to realize temperature compensation.

• Proprietary sensor technology and premium materials from Switzerland
• The robust HA-type glass membrane designed for minimizing alkaline errors and withstand high temperature
• Pre-pressurized reference system for smooth electrolyte flow in viscous liquid samples
• Silver Ion Trap Reference System ensures a stable reference potential and long service life.
• Built-in temperature sensor for automatic temperature compensation
• Lead-free glass body
