Description
The Milwaukee MW11 Total Chlorine Tester is a high-accuracy, pocket-sized digital photometer that takes the guesswork out of water quality monitoring. By replacing visual color-matching kits with advanced digital sensors, it provides precise Total Chlorine readings—the sum of both free and combined chlorine—essential for industrial, environmental, and recreational water management.
Key Features & Benefits
1. Professional Digital Reliability
Avoid the common errors associated with comparing test strips or liquid drops to a color chart. The MW11 features a large LCD display that gives you a direct, numerical reading, ensuring consistency regardless of the lighting or the user’s perspective.
2. Proven Photometric Method
Utilizing an adaptation of the USEPA method 330.5, the MW11 measures the color intensity of a DPD-reacted sample using a dedicated 525nm LED and a silicon photocell. This laboratory-grade technology delivers accuracy within ±0.03 ppm.
3. Comprehensive Chlorine Monitoring
While free chlorine indicates immediate disinfecting power, measuring Total Chlorine is critical for identifying chloramines (combined chlorine), which can cause irritation and decrease disinfection efficiency in pools and wastewater.
4. Compact & Field-Ready
Built for durability and ease of travel, the MW11 fits easily in a lab coat pocket or a technician’s toolkit. It is specifically designed to perform in humid or outdoor environments where traditional lab equipment cannot go.
5. Efficient Power Management
To maximize portability, the meter runs on a single AAA battery. It also includes an Auto-Shutoff feature that triggers after 2 minutes of inactivity, preserving battery life for hundreds of tests.
