Lovibond® MD 110 Colorimeter, Chlorine/Bromine/pH/Cyanuric Acid/Alkalinity‑m/Calcium Hardness, Tablet Reagents, Bluetooth®

Lovibond® MD 110 Colorimeter, Chlorine/Bromine/pH/Cyanuric Acid/Alkalinity‑m/Calcium Hardness, Tablet Reagents, Bluetooth®

The Lovibond® MD 110 is a portable, waterproof colorimeter designed for multi‑parameter water analysis using high‑stability tablet reagents. With Bluetooth® connectivity, LED interference‑filter optics, and a rugged IP68 housing, the MD 110 delivers fast, accurate, and reproducible results in the field or laboratory. It is ideal for pool and spa service, drinking water, wastewater, industrial water, and disinfection control applications.

Key Features

• Bluetooth® data transfer: Send results directly to mobile devices or PCs for evaluation, reporting, and CSV export.
• Waterproof IP68 design: Floats if dropped; watertight for up to 1 hour at 0.1 m.
• Accurate LED/IF optics: LEDs with interference filters ensure stable, reproducible measurements.
• User calibration mode: One‑point calibration with display options in ABS or %T.
• One‑time‑zero function: Zero once per sample; no need to re‑zero between tests.
• Automatic data storage: Stores the last 16 readings with time/date stamp; exportable via IRiM or Bluetooth®.
• Scroll‑driven menu: Simple interface that automatically recalls the last test used.
• Factory programmed: Up to 14 calibration curves pre‑installed for immediate use.
• Portable ergonomic design: Compact housing with rubber feet for stable bench‑top operation.
