2839-2842电导率探头详细英文介绍
2839-2842 NPT Conductivity-Resistivity Electrodes
The 2839-2842 Conductivity/ Resistivity Electrodes are available in four cell constants from 0.01 to 10.0 cm-1, and are suitable for a wide variety of applications from high purity water quality monitoring to weak acids and bases. 316SS electrode surface finishes are controlled in a precision bead blasting operation to ensure measurement accuracy and repeatability.
The PEEK™ insulator and process connections are injection over-molded to minimize variance between electrodes. Double threaded connections in either 3/4 in. NPT or ISO 7/1-R 3/4 enable quick and easy installation in submersible or in-line configurations. Transmitter integral mounting kit and junction boxes are available as accessories.
