Our digital scale allows you to weigh small letters, parcels and large boxes all on the same device, and can handle packages weighing up to 40kg. Our scale is compact so you can easily store it in between uses or designate a permanent space on your desk for it. It has large buttons and a clear digital display, making it quick and easy to weigh your parcel and have accurate information when paying for postage.You can use the scales with an AC power adaptor (not included) or, if you are short on outlets, 4 standard AA batteries (not included). To save on power, the scales will automatically turn themselves off after a period of inactivity. The weighing scales measure 26.5cm (L) x 22cm (W) x 6.5cm (H), keeping them compact if you are short on desk space. They weigh just 1.3kg too, making them easy to move around your home office space.When you move the scales to another surface, they will auto-calibrate to give you an accurate reading. The display is backlit to make it easier to distinguish each weight as well. For parcels weighing up to 5kg, it has 5g resolution and for heavier parcels weighing up to 40kg, it has 10g resolution. For the larger parcels that obscure the display, you can use the auto hold feature from 10g and upwards. It comes with an overload indicator and an adjustable holder for parcel tubes.
