A top loading balance is a precise, durable, and versatile weighing instrument that offers a wide range of capacities, from 120 g to 64 kg, and readabilities from 1 g to 0.1 mg. Top loading balances are designed to meet the demanding needs of laboratory and manufacturing environments and are used for various applications such as sample preparation, formulation, counting, and statistical quality control.
You can be sure of accurate and reliable weighing results thanks to METTLER TOLEDO's high performance weighing cells and quality construction.
Touchscreen operation, built-in applications, a weighing-in guide, easy results transfer, and more make your daily weighing tasks fast and efficient. Trust in METTLER TOLEDO's quality for outstandingly reliable performance.
With metal housings, overload protection, and high-quality materials, our top loading balances are built robustly to ensure reliable performance for many years to come.
Cleaning your top loading balance is quick and easy, thanks to smooth surfaces and rounded edges as well as cleverly designed weighing pans that simply lift off. Download our free cleaning guide and SOP.
The patented SmartPan™ weighing pan minimizes the effects of air movements on the weighing cell, providing high weighing stability. Results are delivered up to twice as fast and repeatability is significantly improved.
LabX™ laboratory software works with our XPR and XSR top loading balances to take care of all your data automatically, provide central control of instruments, task and users, and support compliance with 21 CFR part 11. Read more
RS232, USB and LAN interfaces make it easy to connect peripheral devices such as a printer, barcode reader, or even a PC. Our Bluetooth® and WLAN options enable wireless connection.
XPR and XSR top loading balances feature the StatusLight™, which is built into the front of the display. It's easy to see if you have the green light for safe weighing.
From large adjustable feet to onscreen instructions to electronic guidance and level warnings, METTLER TOLEDO top loading balances make it easy for you to level your balance—a crucial activity to ensure accurate results.
All METTLER TOLEDO top loading balances feature a range of popular applications to simplify your daily weighing tasks, including checkweighing, piece counting, formulation, statistical quality control, and more.

A top loading balance is a weighing instrument in which the weighing pan is located above the load cell. As per this definition all METTLER TOLEDO precision balances are top loading balances. Some analytical balances are also top loading balances – whenever they have the weighing cell located beneath the weighing pan. On the contrary, Excellence analytical balances that have the weighing cell in the back are front loading balances
Top loading balances are used in both laboratory and production environments, wherever precision weighing is required. Applications range from research and development to quality control in a variety of industries, such as chemical, pharmaceutical, food and academic. Typical weighing uses for top loading balances include:
The following videos show how METTLER TOLEDO top loading balances can simplify your formulation processes:
A top loading balance shows between 0 and 4 decimal places to the gram (1 g to 0.1 mg). The number of decimal places indicated on a top loading balance is given in the datasheet and in the METTLER TOLEDO naming convention: The last numeric digit in the model designation of METTLER TOLEDO top loading balances is the readability in decimal places. In case of a XPR204S, the last numeric digit is a 4 – hence 4 decimal place readability (0.1 mg). Similar approach can be applied to the other balance lines (XSR, MS, ML-T, ME, ME-T, PL-E). In the case of MS303TS, the last numeric digit of MS3003TS top loading balance is a 3, thus 3 decimal place readability (1 mg = 0.001 g).
