The Mettler-Toledo PL-L series electronic balance is a portable balance with a readability of 0.01g to 1g and a weighing range from 210g to 6.1kg. In addition to the basic operations of weighing, de-skinning, and adjusting and calibrating the balance, the balance also has various additional functions such as “recalling the weighing value”, “counting the weighing” and “percentage weighing”.
