Description
The Hach DR1900 Portable Spectrophotometer is designed for water analysis in a variety of environments, providing a versatile solution for users who need to take their equipment into the field. The DR1900 is built for rugged conditions. Built as a hand-held spec the DR1900 has a large, clear screen and a simple user interface that makes testing easier than ever in even the most demanding conditions.
Here’s a summary of the Hach DR1900:
- Portability: The DR1900 is a lightweight, handheld spectrophotometer, making it suitable for on-the-spot testing in various environments, including difficult field conditions.
- Broad Range of Tests: It can carry out the most tests of any portable instrument, accommodating over 220 pre-programmed Hach methods, covering a vast range of parameters and applications.
- User Interface: The instrument typically features an intuitive interface that guides the user through the testing process.
- Data Storage: The DR1900 often comes with a memory function to store test results, which can later be transferred to a computer or other device.
- Durability: Built to withstand harsh conditions, it’s typically designed with a rugged exterior to resist impacts, and it may also be waterproof or water-resistant to a certain extent.
- Versatility: The spectrophotometer can read various sample cells, from 1-inch round cells to 10 mL, 20 mL, and 1-inch square quartz cuvettes.
- Light Source: To ensure a broad range of detection, the DR1900 often uses a xenon flash lamp, which is suitable for many wavelengths, and thereby can measure a vast range of parameters.
- Accessory Compatibility: The device is often compatible with a range of accessories like battery packs, carrying cases, and more to aid in field operations.
Benefits of the Hach DR1900:
- Flexibility: It can be used in labs as well as in the field.
- Accuracy: Despite its portability, it doesn’t compromise on the precision of results.
- Ease of Use: With pre-programmed methods, even complex water analysis becomes straightforward.
Potential Limitations:
- It might not have all the advanced features or the extended wavelength range of some benchtop models.
- Battery life, depending on usage and conditions, might be a concern for extended field operations without access to charging facilities.
