The eXact Micro 10 photometer from Industrial Test Systems has been voted by readers of US publication Pool & Spa News as one of the "Top 50 Products of 2011".

The annual readers'choice award apparently recognised the eXact Micro 10 for its "accurate and reliable on-site water testing results".

ITS says the product is the first meter to read combined chlorine directly with 0.01 precision without the need for calculations, and the product tests for 40 water parameters using test strips.

Aimed at pool and spa professionals, the eXact Micro 10 directly reads free, total and combined chlorine, pH, total alkalinity, calcium hardness, cyanuric acid, salt, phosphate and transmission. In transmission mode, the unit reads additional parameters with the use of a conversion table.
