Product Number: D3422B3.99
Ultimate accuracy from ultra-pure to high conductivity applications.
Contacting conductivity sensor with a nominal cell constant k = 0.5 cm-1, ¾-inch NPT PVDF compression fitting, 7 m digital cable, and titanium electrode.
Measuring range 0 - 1000 µS/cm, 0.001 - 20 MΩ.
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.
These enhanced performance sensors measure from 0.057 µS/cm or 18.2 MΩ (theoretically pure water) up to 200,000 µS/cm.
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.
Non-Metallic General Purpose Sensors
Have graphite electrodes and ¾-inch male NPT threaded PPS bodies. Mount into a standard ¾-inch pipe tee, 1-½-inch Hach union hardware (for cell constant k=10 sensor only), or fasten onto the end of the pipe.
High Pressure and High Temperature Sensors
Are designed for monitoring boiler water and condensate in return lines. They have 316 stainless steel electrodes and threaded bodies (¾-inch male NPT). They can be fastened into a boiler wall using a ¾-inch weldolet or mounted into a process line using a standard ¾-inch stainless pipe tee.
Sanitary Clean-in-Place (CIP) Style Sensors
Have 316 stainless steel electrodes and an integral 1-½-inch or 2-inch flange. These sensors can be installed using standard sanitary mounting hardware.
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.”
