Introduction
The BK-WA2004 is a benchtop spectrophotometric water analyzer designed for routine water quality monitoring in laboratories and industrial environmental control. It provides direct concentration readouts for parameters such as COD, ammonia nitrogen, total phosphorus and total nitrogen, delivering repeatable and accurate measurements for process control and compliance testing.

Key features

• 7-inch color touchscreen for an intuitive user interface and straightforward operation.
• Measures common water quality parameters (e.g. COD, ammonia-N, total P, total N, permanganate index, arsenic, total chromium). Certain selections require a digester.
• Factory-installed calibration curves with support for up to 200 user-defined curves.
• Large-capacity storage able to save over 5,000 experimental records for review and backup.
• High-precision filtering combined with narrow-band interference technology to minimize stray light and stabilize measurements.
• Supports multiple colorimetric methods (cuvettes and colorimetric tubes) for flexible sample handling.
• Built-in thermal printer for immediate printing of current and stored results.
• Imported cold light sources with a service life up to 100,000 hours.
• ARM9 processor for responsive operation and up to 500 MB memory capacity.
• USB data export for centralized processing (e.g. Excel).
