BUS

At HACH LANGE you will find information regarding the broad range of sensors and controllers for process automation and the seamless integration into Process Control and Asset Management Systems.

Digital communications portfolio

HACH LANGE goes beyond the traditional 0/4-20mA signal to provide the widest range of digital communication capabilities in the world of online sensors and controllers for water and waste water analysis. These sensors help with secure and efficient operation of treatment plants. They can be integrated easily into common Process Control and SCADA systems. 

Process Logic Control (PLC) and Asset Management Systems  
They can be integrated easily into common Process Control, Asset Managemnt, Programmable Logic Control (PLC), and SCADA systems.
