Overview
The Hach DR1900 portable spectrophotometer excels in the field because of the lightweight and compact design. The DR1900 is built for rugged conditions, and it’s flexible, --accepting the widest range of vial sizes.
Built with field use in mind, the DR1900 has a large, clear screen and a simple user interface that makes testing easier than ever in even the most demanding conditions.
Advanced Testing
Easy to hold, and operate, the compact DR1900 is a valuable tool for your field technicians. Underneath the rugged exterior, the DR1900 has the largest number,-- over 220-- of the most commonly tested preprogrammed methods already built in. You can also use the easy-to-use interface to create your own methods.
Tests are performed with a wavelength range of 340 to 800 nm which make this a field instrument you can use to find results typically only seen in laboratory instruments.
Notes
Reagents listed below are EPA approved. For the full list of reagents and methods that can be used with the DR1900, refer to the Hach Methods Quick Reference Guide

Data-Driven Decisions: Tracking Sediment during the Klamath Dam Removal
The largest dam removal in U.S. history, the deconstruction of the Klamath Dam is slated to begin this summer. The project includes four dams along the Klamath River with the first and smallest dam, Copco #2, scheduled for removal first. As each of the dams are torn down, scientists and consultants will keep a close eye on the state of the Klamath River downstream to assess the impact of undamming the river. 
 
Shawn Hinz, managing partner and environmental toxicologist with Gravity Consulting , has been involved with the Klamath Dam project for over a decade. Hinz was a part of these earlier steps, representing the academic stakeholder position as a graduate student sitting on a board of other stakeholders.

In regions with historically secure access to clean drinking water, few think about the work that goes into ensuring that the water they fill their cups with is safe. In reality, millions of dollars are invested in the infrastructure, equipment and teams involved in converting source water into drinking water. 
 
While all the work that goes into providing clean water often goes unnoticed, analysts like Michele Gilkerson, a water research analyst with the City of Columbus Division of Water, know exactly how much goes into securing safe water for millions of people. 
 
Gilkerson started with Battelle Memorial Institute in 1991 in their water ecology section. There, she saw how interesting source water monitoring could be, even though it isn’t often spotlighted in the environmental sector.
Read MoreChoosing the Right Water Quality Monitoring Systems Is Crucial for Stantec Inc.
Data is king when it comes to water quality monitoring. It is not merely the type of data being collected that matters but also how that data is stored, processed and presented. When Joseph Kamalesh, a project manager with Stantec Consulting Services Inc. , needs to find the right equipment for large client-based projects, he knows to keep these factors in mind. 
 
Joseph has a background in water quality and water flow monitoring instrumentation, which he continues to focus on at Stantec. During college and his early career, Joseph gained experience with water instrumentation, consisting primarily of on-site wastewater sampling and sampling small systems.
