Overview
The Hach Intellical CDC401 is a digital, graphite, 4-pole conductivity cell with a temperature sensor. This Rugged CDC401 version is built with a stainless steel body, ensuring sufficient weight to the probe for easy outside handling, the sensing part is protected by a shroud, and the connection is ensured by strong and visible yellow cable onto which you can clip depth markers (optional accessories), making the CDC401 rugged models specially designed for field use.
Applications
The Hach CDC401 is available with a 5, 10, 15, or 30-meter cable. The CDC401 Rugged is ideal for measuring electrical conductivity, salinity, resistivity, or total dissolved solids (TDS) in all types of external environments such as rivers, surface and ground waters, ponds, lakes, sea, wastewater plants, source waters, drinking water reservoirs for water quality, environmental and treatment process purposes.

Have You Heard? AI Buoys Revolutionizing Marine Mammal Monitoring in Whangārei Harbor, New Zealand
In one history, Whangārei Harbor, nestled in the lush hills of New Zealand’s North Island, gets its name from the Māori, “waiting for the breastbone of the whale.” It seems fitting, then, that it’s now home to state-of-the-art acoustic monitoring buoys listening for marine mammals around the clock. 
 
In September 2024, a team from Auckland-based underwater acoustics firm Cetaware Ltd installed NexSens buoys in Northport, a major commercial port at the entrance to the Whangārei Harbor. 
 
The first buoys to be installed by Cetaware in a permanent setting running 24/7, they use real-time artificial intelligence (AI) models to passively sense Delphinidae–from common dolphins to orcas.

Human interaction has negatively impacted the hundreds of streams that run through Southern California. Man-made river and stream diversions, channeling, and damming have changed the physical and chemical characteristics of these waterways. In addition to physical impairments, climate change is increasingly impacting the ecosystems of streams. 
 
To evaluate and mitigate these negative impacts, local groups are monitoring the riparian habitats of these streams and are conducting water surveys that document rainbow trout populations and evaluate water quality .

Freshwater covers less than 1% of the Earth’s surface but has an outsized impact on global ecosystems, supporting more than 10% of all known species, reports the World Wildlife Fund . Freshwater environments such as rivers and wetlands provide significant scientific, economic, and cultural value. But pressure from climate change, biodiversity loss, and a lack of prioritization in environmental policies mean freshwater habitats are recognized as one of the most threatened in the world–something scientists have dubbed an “invisible tragedy. ”
