FiveEasy Plus FP20-Kit by Mettler-Toledo GmbH

"The FiveEasy plus is simple to use. Mettler-Toledo has an online diagnostic tool that will direct you to what steps need to be taken to remedy any problems. The electrodes that come with the instrument are budget level. We have gone through a couple pH electrodes in a short period of time, but I think that might have more to do with mishandling of the electrodes. The web site is a little bit troublesome; they have a tool to help select electrodes for your meter, but none of the electrodes that come with the meter are on the recommended list. The web site also has very limited information on the products. There is a lot of marketing info, but it is short on actual usable information. Overall, it is a solid instrument, but could do better with support and documentation."
