Mechanical Balance Scale Tray, Balance Tray Table Mechanical Balance Scale, Physics Experiment Teaching Tools, with Weight Kit&Tweezers, Lab Mechanical Balance Scale, Not Easily Worn, for School

Feature:Accurate weight measurement based on the lever principleUse tweezers to hold the weight and keep it clean and accurateA teaching tool suitable for school physics and chemistry experimentsNote1. For manual measurement, please allow a deviation of 1-2 mm2. Due to the difference between the light and the screen, the color of the item may be slightly different from the picture

• BEFORE USE: Before using the balance, make sure it is placed on a horizontal table and cannot be tilted; make sure that there is no liquid and powder in the trays at both ends of the balance; needs to be reset to 0; adjust the balance nut so that the balance pointer points to the middle
• WHEN IN USE: Put the object to be loaded on the left side of the balance, add weights to the right one by one or adjust the scale of the . After the left and right balances, remove the weights. The number marked on the weight plus the indicator is the measured object Actual weight
• HIGH CALIBRATION ACCURACY: Clamp the weight with tweezers, the weights are stored in the box for better of the weights so that the results are more accurate;Please remove the rubber shipping grommets before use. Achieve precision weight measurement based on lever principle
• APPLICATION: The double pan balance scale suitable for scholastic physics and chemical experiments, an teaching tool. This Mechanical Tray provides an accurate count and tare weighing function ensures more result. It can be also used as Lab scale, powder scale, carat scale and more
