Tovatech Is Proud To Offer the Following Scientific Scales
Analytical Balances
Capable of weighing to within the sub-milligram range such as 0.1mg or in the case of semi-micro balances within 0.01mg readability. Upper weighing capacity is limited for analytical balances, depending on the models. Weighing pans are enclosed to protect them from dust and stray air currents that can affect accuracy.
Precision Scales
Higher weighing capacities and weighing ranges from readings in milligrams (0.001g) to a capacity of 31,000g, depending on models. Most models have open weighing pans; others are enclosed for draft protection. Some models can be fitted with draft shields.
Platform Scales
Also known as parcel scales and packaging scales, used for heavier weighing tasks. Readability varies depending on the weighing capacity. As an example, a 3kg maximum weight scale might have a readability of 0.01g while a 300kg scale might have a readability of 100g.
Hanging Scales
Popular for receiving docks and warehouses to check the weight of merchandise as it is unloaded or relocated using an overhead crane. Tovatech’s HCN digital hanging scales have stainless steel housings and an IP65 rating for ingress protection against dust and moisture. They feature front and rear weight displays and a weight holding function.
A Primer on Scientific Scale Selection Criteria
Precision and Accuracy
There's an important difference between precision and accuracy as selection criteria when specifying scientific scales and analytical balances. For example, your digital wristwatch may be precise, but if the time displayed is wrong it does not show the accurate time. Repeatedly placing a test weight of known mass on a weighing scale may show the same result, meaning the scale is precise. But if the test weight and the readout differ, the scale has an accuracy problem.
- Linearity: The plus or minus deviation of the readout from the actual load on an analytical balance over its weighing range.
- Readout: Also termed Readability and Resolution, is the smallest difference in weight that can be read and displayed by the unit.
- Repeatability: The ability of a balance to display the same result when an object is repeatedly placed on the weighing pan and removed.
Application Examples
- Density determination
- Piece counting
- Tolerance weighing (check weighing)
- Recipe weighing
- Percentage weighing
- Dynamic weighing
Maintaining Your Digital Scales
Regular calibration is important for maintaining accuracy. For more information, see our post on calibrating scientific scales.
