all my meters are hanna, ive used them for yrs, i have an EC meter of theres for over two yrs and still good, youll need to buy a 250 ml bottle of both buffers PH and another for the EC , check them at leat once a week, and everytime they recieve a knock! i have noticed the price dropping over the last two yrs or so. the cheaoest model used to cost 120 euros !, the PH meter electrodes always go quicker so i like the spare to go with it ! very good choice, although i do prefere to keep my EC and PH meters seperate for practical reasons[ if one breacks i still have the other parameter to use! and dont loose all control]

welcome to the world of endless possibilities,,, hydroponics!
