Introduction

HACH/GLI Contacting Conductivity Sensor, Low Conductivity (k=0.05), with ½" PVDF Compression Fitting

Ultimate accuracy from ultra-pure to high conductivity applications.

Contacting conductivity sensor with a nominal cell constant k = 0.05 cm-1, ½-inch NPT PVDF compression fitting, 6 m analogue cable, and titanium electrode.

Measuring range 0 - 100 µS/cm, 0.002 - 20 MΩ.

Benefits

High Performance Design

These sensors are manufactured to exacting tolerances using high quality, rugged materials for demanding applications including ultra-pure water, clean-in-place (CIP), and boiler/condensate monitoring. Each sensor is tested to determine its unique, absolute four-digit cell constant. Also, each sensor has a PT1000 RTD temperature element built into its tip for exceptionally fast response to changes in temperature with ±0.1 ºC accuracy.

Versatile mounting styles

Compression Fitting Sensors feature titanium electrodes and a compression fitting for universal installation with up to 102 mm insertion depth. The ½-inch or ¾-inch male NPT compression fitting are offered in PVDF or 316 stainless steel. A longer version of this sensor is available for use with a 316 stainless steel ball valve hardware assembly to insert/retract the sensor form the process without stopping the flow. The longer version can also be used for insertion through a compression fitting. Maximum insertion depth is 178 mm.

Resistivity and Conductivity Measurement Capability

These enhanced performance sensors measure from 0.057 µS/cm or 18.2 MΩ (theoretically pure water) up to 200,000 µS/cm.

Full-Featured “Plug and Play” with Digital Hach SC Controllers

There are no complicated wiring or set up procedures with any Hach SC controller. Just plug in any combination of Hach digital sensors and it's ready to use—it’s “plug and play.”
