PH/Conductivity Analyzer


The SC200 Universal Controller is the most versatile controller on the market. It allows the use of digital and analog sensors, either alone or in combination, to provide compatibility with the broadest range of sensors. It replaces the Hach SC100 digital and GLI53 analog controllers with advanced features for easier operator use. The SC200 controller can be configured to operate two digital sensor inputs, two analog sensor inputs, or a combination of one digital and one analog input. Customers may add communication modules for a variety of protocols including Modbus 232/485, Profibus DPV1, and Hart.

3400 Digital Contacting Conductivity Sensors

These enhanced performance 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 Pt 1000 RTD temperature element built into its tip for exceptionally fast response to changes in temperature with ±0.1ºC accuracy.

Digital Differential pH Sensors

Hach pHD sc Process pH Sensors with Integrated Digital Electronics for Plug and Play Capability with Hach's Digital SC Controllers.

The inline process pH sensors feature exceptional performance due to the Differential Electrode Measurement Technique. This field-proven technique uses three electrodes instead of the two electrodes used in conventional pH sensors, resulting in unsurpassed measurement accuracy, greater reliability, and less downtime and maintenance.
