The MD 640 has all the features of the MD 610, with added florescence capability for the determination of PTSA in water systems.

PTSA (1,3,6,8 pyrenetetrasulfonic acid, sodium salt) is a fluorescent material that is being increasingly added to specialty water treatment products to enable real time product dose analysis.

PTSA is detectable at ppb levels, is non-toxic and chemically stable, making it an ideal additive to trace throughout complex water systems.

The MD 640 has a built-in UV excitation LED that enables accurate detection and quantification of PTSA from 0 to 1000 ppb. No additional adapters or reagents required, just insert the sample and read the result.

Accurately measuring product dose levels help the water treatment specialist to control water chemistry; prevent corrosion, scale and biological fouling; increase system efficiency and ultimately save energy and costs.

The MD 640 is pre-programmed with over 120 analytical methods to enable quantification of naturally occurring dissolved metals and non-metals such as copper, iron, calcium, magnesium and carbonates, plus a range of water treatment additives such as DEHA, Molybdenum phosphate, poylacrylates, PTSA, organo-phosphate (phosphonates) and more empowering the field engineer to effectively manage many different water systems and treatments with one compact, waterproof and rugged handheld device.
