Double Pan Weighing Balance

• This device is a specially-designed electronic 'differential scale' for a peculiar use in blood banks. It measures two weights independently and displays how much which side is lighter than the other side.


• For plasma separation from whole blood, blood bags are loaded in high-speed centrifuges. It
  is an essential process in blood banks that, before being loaded into centrifuges, weight of the
  two loads (each blood bag + bucket) has to be matched to be same or very close, otherwise
  weight unbalance could damage the centrifuges.


• This simple device makes weight-balancing process very simple, accurate and speedy. It will
  be a perfect way to save valuable centrifuge machines, as well as labor.

Features

• Has two independent weight sensors, and displays weight difference.
• How to use:

- Operators put two buckets (with blood bags in each bucket) on both plates.
- Display shows weight difference and an indication lamp at the lighter side turns on.
- Operators just add a few weight-chips (e.g. 1 gram each) into bucket until 'GOOD' lamp turns on. The lamp turns on when weight difference becomes less than allowance.

• Accurate, simple and very easy to use.
