AI3168 LabSen 851-H Pre-Pressurized Glass-body pH Electrode for Highly Viscous Samples with Strong Alkali or High Temperature by Apera

LabSen 851-H pH electrode is designed for high-accuracy pH measurement of highly viscous samples with strong base or high temperature.

The pre-pressurized structure allows the electrolyte to stably flow out even in highly viscous samples so as to ensure reliable measurements.

HA Glass Membrane - better accuracy and repeatability in strong alkaline solutions (10 to 14 pH), minimizing alkaline errors.

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.

• PHY glass membrane made for high-temp. and caustic solutions
• Proprietary sensor technology and premium materials from Switzerland
• LabSen HA-type glass membrane designed for strong alkalis (pH 10-14), minimizing alkaline errors
• Pre-pressurized reference system for smooth electrolyte flow
• Silver Ion Trap Reference System ensures a stable reference potential and long service life.
• Lead-free glass body

CS200TC-K=1 Light Duty Online Conductivity Sensor, Platinum, 12mm, TC, K=1.0 by Sensorex

The CS200 and CS200TC conductivity probes are a cost effective solution for measuring conductivity in light industrial and laboratory applications.

Models CS200 and CS200TC feature platinized measuring surfaces that provide accurate and repeatable measurements. Rugged epoxy bodies make the sensors virtually unbreakable. These are an excellent choice to use as standard laboratory conductivity electrodes.

By adding a simple mounting gland fitting, customers may use these in process applications. Mount them in-line, in a pipe "T" fitting, or submerse them into a tank.

Features

• Ideal for laboratory and light duty process applicationsAvailable with or without ATC (temperature sensor)
• Easy to submerge in a tank or mount inline in a pipe
• Cell constant choices of 0.1, 1, or 10
• Compatible with most portable and benchtop meters
