Vendeur: daren19680_0 (2.064) 100%, Lieu où se trouve: London, Lieu de livraison: GB et de nombreux autres pays, Numéro de l'objet: 162301400146 Hi There I am selling this Aquatronica Multi tester which I bought when I purchased the complete Aquatronica system. It is new and never been used. Please see the manufacturers description below. I am happy to answer any questions. MANUFACTURERS DESCRIPTION: The AQUARIUM MULTITESTER is an electronic device able to read all the most important aquarium values (Temperature, pH, Redox, marine Density, Conductivity, Level and Water Leakage): it allows to read every value indicated above (two values can be controlled at the same time) and all the data is displayed on the same screen (thanks to the two USB connections). The MULTITESTER can be reprogrammed by the use of our PC interface (ACQ220) and also features an Electronic Diary function for the management of regular and special maintenance.
