Rice Lake TA-120 laboratory balance utilizes the highest performance weighing sensor on the market for fast and reliable start-up. When selecting a four decimal place balance, one of the main specifications you need to look at is its linearity. While the displayed resolution will show you how the scale graduates, it isn't telling you anything about how accurate the readout actually is. Linearity tells you more about the level of accuracy and the facts speak for themselves. In addition, Rice Lake's unique weighing sensors do not require A/D converters, analog circuits, or magnetic coils which cause complex temperature characteristics. This is why Rice Lake balances maintain incredibly long-term stability and each balance is covered by Rice Lake's 5-year limited warranty and comes standard with internal calibration.
