机电两用电子地中衡是由机械式地中衡改造而来的,它具有很多优点:机械式地中衡经电子化改造后,机械衡原计量性能不变,游铊读数和数字显示示值一致,但两个系统各自独立,互不干扰,使用起来非常方便。成本低、价格低廉,机械式地中衡的改造费用约是全电子地中衡的10％-20％,这样对那些经济实力有限,但又想使设备升级的企业无疑是一种折衷的办法,小投入换来大效果。由于有数字显示,称重结果数值显示快捷、明了,其可信度、透明度大大提高,同时又能与自动打印机联接,这样就避免了人为误差（包括做假）和视觉误差,提高了计量的准
Electromechanical dual-purpose electronic balance is a mechanical balance from the transformation, which has many advantages: mechanical balance after the electronic transformation, the mechanical balance of the original measurement performance unchanged, tour of thallium readings and figures show that The same value, but the two systems are independent of each other without interference, very convenient to use. Low cost, low price, mechanical balance in the cost of reform is about 10% -20% of the electronic balance, so that those who have limited economic strength, but also want to upgrade the equipment business is undoubtedly a compromise Small investment for big effect. Due to the digital display, the weighing result is displayed quickly and clearly. The reliability and transparency of the weighing result are greatly improved. At the same time, it can be connected with an automatic printer, thus avoiding human errors (including fraud) and visual errors, and improving the measurement quasi-
