Thank you for purchasing this high quality METTLER TOLEDO meter. Ease of use, reliable results and
ergonomic design – these are our goals for products.
The Education Line meters have an excellent price/performance ratio and many useful accessories (e.g.
electrode clip and wrist strap for the portable meter) are already included in the standard delivery of the
instruments. Other accessories such as electrodes, solutions, electrode arm for the bench meter or a
carry bag for the portable meter are of course also available from METTLER TOLEDO.
