                         FIRST QUARTER 2005 RESULTS

 -- SOLID LOCAL CURRENCY SALES GROWTH AND STRONG GROSS MARGIN EXPANSION --

                        - - 15% INCREASE IN EPS - -

GREIFENSEE, Switzerland and COLUMBUS, Ohio, USA - May 3, 2005 -
Mettler-Toledo International Inc. (NYSE: MTD) today announced net earnings
of $20.8 million, or $0.47 per share on a diluted basis, for the quarter
ended March 31, 2005. This compares with net earnings per share of $0.41
for the first quarter of 2004.

Sales for the quarter were $337.2 million, compared with $318.7 million in
the prior year. This represents a 6% increase in reported sales, consisting
of a 3% increase in local currency sales and a 3% increase due to currency.
Adjusted operating income amounted to $35.7 million, compared with $32.8
million last year. Operating cash flow in the quarter was $6.7 million
compared with $29.4 million last year.

Robert F. Spoerry, Chairman, President and Chief Executive Officer, stated,
"The first quarter was a solid start to the year. Local currency sales
growth was in line with our expectations and was driven by better than
expected performance in the Americas. In Asia / Rest of World, sales growth
was less than the previous year but consistent with our projections. In
Europe, economic conditions are challenging and sales were down slightly
from last year and below our expectations. We are happy to report another
quarter of strong increase in gross margins over the prior year. This led
to a solid improvement in earnings for the quarter."

Spoerry concluded, "We remain cautiously optimistic for the remainder of
the year. We anticipate sales growth in Asia / Rest of World and Europe to
improve as the year progresses. Our strategic initiatives remain well on
track including many new product launches in the upcoming months. We are
introducing a new line of high-end analytical balances targeted for
applications in regulated areas and a number of exciting new solutions in
our product inspection business."

For the quarter ended March 31, 2005, the Company reported local currency
sales growth of 7% in the Americas and 4% in Asia / Rest of World and a 1%
decline in local currency sales in Europe.

During the first quarter the Company repurchased 528,000 shares of its
common stock.

The Company has reconciled adjusted operating income to the most comparable
U.S. GAAP measure in the attached schedules.

The Company will host a conference call to discuss its first quarter
results today (Tuesday, May 3) at 5:00 p.m. Eastern Time. To hear a live

 Notes:
(a)  The decrease in 2005 resulted principally from approximately $15.0
     million of higher payments relating to 2004 performance-related
     compensation incentives (bonus payments) and the timing of our
     accounts payables disbursements which increased $12.3 million in the
     three months ended March 31, 2005 compared to the corresponding period
     in 2004.
