Overview
The Hach HQD Laboratory Meters are advanced devices designed for water quality experts that utilize digital IntelliCAL probes, which are available for multiple parameters. Measurement data can be stored and transferred to a printer, PC or USB storage device.
IntelliCAL Probes
HQD meters connect with digital IntelliCAL probes and automatically recognize the testing parameter, calibration history and method settings to minimize errors and setup time. The IntelliCAL Red Rod pH electrodes offer exceptional performance and response time across a wide variety of sample types. The LBOD probe utilizes optical technology to provide fast, accurate Dissolved Oxygen (DO) measurements while dramatically reducing maintenance costs.
Additional probes for Conductivity, Total Dissolved Solids (TDS), Ammonia, Ammonium, Fluoride, Nitrate, Sodium, and RedOx (ORP) measurements complete the IntelliCAL portfolio.
Models
HQD Series Meters are Available in Three Models:
- HQ411D - pH/mV/ORP (RedOx)
- HQ430D - Multi-parameter, single probe input
- HQ440D - Multi-parameter, dual probe inputs
Benefits
- Designed for drinking water and wastewater professionals
- Automatic probe and parameter recognition
- Instrument-guided calibration procedures
- Calibration data is stored in the probe
- Probe specific method settings for regulatory compliance and Good Laboratory Practice (GLP)
- Real-time data logging with a USB connection
- Bi-directional communication with PC-based systems with a virtual serial port connection
- Sample ID and Operator ID for data traceability
- Adjustable automatic shut-off
- Durable, robust design to withstand years of use

Supplying Seattle’s Drinking Water: Using Data Buoys to Monitor the Cedar River Municipal Watershed
Providing clean, safe, and reliable drinking water for the 1.6 million people in the greater Seattle area is a top priority for Seattle Public Utilities (SPU). With limited water supplies, SPU dedicates considerable resources to maintain its watersheds and mountain reservoirs. About 70 percent of Seattle Water comes from the Cedar River Municipal Watershed , and the other 30 percent comes from the South Fork Tolt River Watershed .

Data-Driven Advocacy on the Lower Deschutes River
Like many freshwater environments, the Deschutes River in Oregon is under pressure from development, pollution, and climate change. Many rivers, streams and lakes in the Deschutes Basin do not meet Oregon water quality standards –where state water quality monitoring assesses levels of bacteria, pH, dissolved oxygen, temperature, and fine sediment. Hannah Camel is the Water Quality Coordinator for the Deschutes River Alliance (DRA), a non-profit organization that focuses on the health of the lower 100 miles of the Deschutes River–the area most affected by human intervention. As a data-driven organization, the DRA has benefited from the installation of two NexSens X2 data loggers.

Expanding the Port Everglades: Real-Time Monitoring of Water Quality Conditions from Planned Dredging Operation
The Port Everglades in Broward County, Florida, serves large trade vessels and cruiseliners and incoming and outgoing recreational boaters. However, as cargo ships become larger, the port must expand. A dredging project led by the US Army Corps of Engineers will substantially deepen and widen the port's navigation channel to accommodate larger Panamax cargo ships and modern cruise liners. As a result of this project, a large amount of sediment will be displaced into the water column. This suspended sediment may settle outside of the project area, burying benthic organisms like corals, and possibly carrying harmful particulates to other regions. [caption id="attachment_39497" align="aligncenter" width="2560"] A CB-950 and CB-25 deployed on site at Port Everglades.
