You can be doubly confident of the quality. Rirst,because Mettler builds them.

Second, because Arthur H.Thomas tests them.

The Thomas Quality Assurance team takes no product for granted. Not even Mettler electronic balances. We put Mettler PC Series balances through the usual tough Thomas inspection. We took them apart. Tested the electronics and the mechanics. And verified each of the manufac­turer's specs. They checked out first-rate.

We are proud to sell them, because we know how good they are.

Arthur H. Thomas stocks the full line of Mettler PC balances. All eight models. From the PC 180 (with a capacity of 180 g) to the PC 1616 (with a capacity of 16,000 g). Four models are equipped with the exclusive Mettler DeltaRange® feature, the movable fine range that's ten times as accurate as the coarse range.

PC Series balances are precise, fast and conve­nient. A single, full-width bar turns the balance on or off, zeroes, tares, retares and engages the Mettler DeltaRange.

Thomas's order processing and fulfillment sys­tems have also been tested—by buyers of scientific equipment around the world. They know they can
