Measurement made easy
Perfect for use in standard to highly corrosive solutions

Greatly reduces coating and other fouling problems
Inductive measurement technique yields a solution conductivity
measurement virtually unaffected by solution contaminants

Multi-range capability
Measures from 400 µS/cm to 2,000 mS/cm

Versatile mounting
Hardware for submersion, 1½ in in-line and low- and high-pressure ball valve insertion

Automatic temperature compensator with fast thermal response

Small size with large center bore
Enables 1½ in mounting, yet center bore is 50 % larger than comparatively sized sensors

PEEK encapsulation
Assures chemical resistance and durability

High pressure and temperature ratings
Up to 200 °C (392 °F), 2,070 kPag (300 psig), depending on mounting
