  • Picture 1


• Inbuilt PTSA & Fluorescein measurement - no adapter required
• High quality results due to interference filters and long-life LEDs
• Automatic wavelength selection
• Bluetooth® data transmittance to Lovibond® AquaLX® App
• Covers more than 120 important methods for water analysis such as aluminium, chlorine, COD, bromine, chlorine dioxide, copper, iron, molybdate and phosphate
• Advanced data management via AquaLX® App
• Portable and easy handling
• Robust and water proof

The Lovibond® MD 640 is an enhanced version of the MD 610 photometer, offering additional fluorescence capability for the determination of PTSA and fluorescein in water systems. PTSA (1,3,6,8 pyrenetetrasulfonic acid, sodium salt) and fluorescein are fluorescent materials that are increasingly being added to speciality water treatment products to enable real time product dose analysis. Both materials are detectable at ppb levels, are non-toxic and chemically stable, all of which make them ideal tracer additives throughout complex water systems. Accurately measuring product dose levels helps the water treatment specialist to control water chemistry; prevent corrosion, scale and biological fouling; increase system efficiency.
