Lovibond® MD50 Colorimeter – Manganese (Tablet Reagents)

Lovibond® MD50 Colorimeter – Manganese (Tablet Reagents)

Single-parameter colorimeter for precise manganese determination in drinking water, raw water, and industrial applications. The MD50 combines a robust IP67 housing with an optimized optical system for reliable field and laboratory measurements.

Key Features

• Purpose-built for manganese with factory-programmed methods for LR, L, T, and HR ranges.
• Optimized for low concentrations to support regulatory drinking-water requirements.
• Rugged IP67 design with rubber-protected sides and sealed keypad for field use.
• LED light source with spectrometer sensor and interference filters for stable optical performance.
• One-Time-Zero (OTZ): zero once per sample; no re-zero required for subsequent tests.
• User calibration with one-point adjustment and automatic logging.
• User-defined methods available via PC software.
• Data storage for up to 100 results with date/time stamp; retained during battery replacement.
• USB-C and NFC interfaces for data export to AquaLX® app or CSV.
• Compact, ergonomic design with rubber feet for stable bench operation.
