The Sierra Series of precision balances includes four single range models (S Models), as well as two dual range models (D Models). The dual range laboratory balances automatically display the maximum resolution whenever the balance is tared, regardless of how much weight is zeroed out. For instance, the 0.001g resolution of the SI-410D is available up to 100 grams even when taring objects that weigh close to the rated capacity of the precision balance.
A special mode key on the precision balance can be used to perform a variety of functions such as conducting a simple span calibration or activating a unique hold feature that can lock in a displayed weight. This key can also initiate data transfer to a printer or computer. Data transmission can be instantaneous, continuous, or intermittent, as in once every 300 seconds
All precision balances employ our patented, award-winning sensing technology - variable capacitance. This technology requires few parts allowing the laboratory balances to maintain a low profile and remain structurally streamlined both inside and out, providing you with better reliability at a lower price.
A no-nonsense three year warranty that includes replacement parts and labor covers each SI Series laboratory balance
