MD50 Series Photometers
Available in multiple parameter-specific variants, the MD50 combines high-precision optical measurement with straightforward operation, making it suitable for water treatment professionals, laboratory technicians and field engineers.
With integrated data storage, NFC and USB connectivity, guided operation and a rugged IP67-rated design, the MD50 provides a practical solution for routine water quality monitoring across industrial, drinking water, wastewater and treatment applications.
Accurate and Reproducible Results
The MD50 uses a high-precision optical system to provide consistent and reproducible photometric measurements.
Factory-programmed methods simplify routine analysis, while user calibration provides additional flexibility where required. Frequently used methods can also be saved as favourites, giving users quick access to the tests they perform most often.
Simple, Guided Operation
Designed to make routine photometric testing straightforward, the MD50 features a language-independent interface with clear symbols and on-screen animations to guide users through the measurement process.
Additional features include:
- One-Time-Zero (OTZ) for more efficient routine testing
- Quick-access favourites for frequently used methods
- User calibration capability
- User-defined method programming via PC software
- Clear, intuitive navigation
These features help simplify day-to-day operation and provide a consistent testing process across different users and locations.
Flexible Data Management
Test results can be stored, transferred and incorporated into wider reporting and record-keeping processes.
The MD50 provides:
- Storage for up to 100 test results with date and time information
- Wireless data transfer via NFC to the AquaLX® App
- USB connectivity for PC integration
- CSV data export for reporting and further analysis
- GLP-compliant data documentation
This makes it easier to retain measurement records and transfer results from testing in the field or laboratory.
Built for Field and Laboratory Use
The MD50 combines a compact handheld format with a rugged housing designed for regular use in demanding environments.
An IP67-rated enclosure provides protection against water and dust ingress, while protective rubber side panels improve handling and help protect the instrument during field use.
Integrated anti-slip feet also provide stability when the photometer is used on a laboratory or workbench.
Water Testing Applications
With different single-parameter variants available, the MD50 Series can support water analysis across applications including:
- Boiler water monitoring
- Cooling water treatment
- Drinking water treatment
- Wastewater treatment
- Raw water analysis
- Disinfection control
The ability to select an MD50 for a specific parameter provides a straightforward option for applications where dedicated routine measurement is preferred over a multi-parameter photometer.
