Save time and money â€“ weigh envelopes and packages at your desk With the compact, accurate DYMO M5 Digital USB Postal Scale, you can weigh envelopes and packages without a trip to the Post Office â€“ or without even leaving your desk! Weigh envelopes and packages up to 5 kg (11 lb) on the 20 cm x 20 cm (7.9â€ x 7.9â€) platform. The DYMO M5â€™s LCD screen displays weight in easy-to-read digital format â€“ in kg/g (0 kg 000g) or lbs/oz (0 lb 00.0 oz). The LED illuminated â€œholdâ€ feature continues to display the weight for 10 seconds after you remove your envelope or package - perfect for weighing larger items that block your view of the display. The tare function lets you weigh items in a container without including the container weight. The automatic shut-off feature conserves batteries when the scale is not in use. And at just 23.4 cm L x 21.1 cm W x 4.5 cm H, the DYMO M5 fits in the busiest workspace and stores neatly in most desk drawers. Free DYMO Scale Software.
