Laboratory Scales

You want to know, first of all, what is a laboratory scale .. Scales, whose operation is based on the use of gravity, hydrostatic, electrostatic or electrodynamic effects .- a device to measure weight and body weight. Laboratory scales are designed for static mass measurement in the laboratory of enterprises and organizations. These scales are manufactured using the latest advances in science and technology and are endowed with the highest values of accuracy. As the choice of any other equipment, and selection of laboratory balances – is a serious problem because of the large amount of both producers and their models each with its own parameters and functions. We will try to help you understand the choices, but first talk a little about theory. All scales can be divided into mechanical, electromechanical and electronic.

The greatest spread recently received electronic laboratory balances, the design which includes a sensor that transmits a signal in a certain way of load indicator. From the sensors, which are of various kinds, in largely dependent characteristics of the scales. Strain gauges and sensors of the electromagnetic compensation – the most common of them, an advantage which is well-regulated mass production and relatively lower their costs. Scales based on electromagnetic sensors compensation have higher accuracy, sensitivity and resolution than the scales based on strain gauges. But, unfortunately, they do have drawbacks, namely, sensitivity to magnetic fields. Here are some basics to consider when choosing the weights: – Weighing (NEC) – the maximum static load that can withstand the scales without affecting the metrological characteristics.
