Electronic Balances

  1. Basics about Balances

    Basics about Balances

    Electronic balances used in the laboratory are typically classified as "high precision" or "precision" balances. As such, there are a number of choices - depending on the requirement in the lab. The "high precision" choices mayb include Micro Balances that are capable of determining masses in the level of 1 million parts of a gram and Semi-micro Balances that, generally, determine masses in one-hundred parts of a milligram.

    What is NTEP? Why should I buy an NTEP Scale?

    The National Type Evaluation Program & Why You Need it Many people ask why they should use an NTEP (Legal for Trade) scale or balance instead of any old scale, surely all scales are the same?

  3. What Does Under Balance Weighing Mean?

    What Does Under Balance Weighing Mean?

    Where is my Hook? Many of our balances are fitted with an under weighing hook facility, for under balance weighing. These hooks are sometimes used to weigh large or bulky items that might otherwise not fit on the platform but more usually they are used in density calculations where the item to be weighed is suspended, first in air and then in water, to determine the density of the item.

  4. How to Calibrate Balances and Scales

    How to Calibrate Balances and Scales

    Why does my Balance need Calibration? Many people have questions concerning whether or not a balance or scale needs to be calibrated. The short answer is Yes! Scales and balances, in fact all modern instrumentation, need to be calibrated to ensure that they are in compliance with the specifications quoted. Having said that, how often to calibrate is more vexing to establish.

  5. What Does "Fast Count" On My Scale or Balance Mean?

    What Does "Fast Count" On My Scale or Balance Mean?

    What Does “Fast Count” On My Scale or Balance Mean? Counting scales are often used for inventory control. They are therefore often used by staff who have not been trained in the scale’s operation.

  6. What Does Linearity Mean in a Balance or Scale?

    What Does Linearity Mean in a Balance or Scale?

    “I often see linearity quoted as part of a balance or scale specification, but what does it mean to me?” Balances and scales are very precise instruments and like all instruments, they perform within stated parameters. Other examples of these parameters will be dealt with in other sections, but for now we will concentrate on Linearity.

  7. The Importance of Environment When Using a Balance

    The Importance of Environment When Using a Balance

    The environment surrounding a balance is vital if you are to maintain the manufacturers stated performance ratings. Really, the manufacturer doesn’t matter in this regard, as a bad environment will adversely affect any balance. There are many influences to consider and to remove, as far as is possible, from the area surrounding the balance.

  9. What is the Minimum Load of a Balance?

    What is the Minimum Load of a Balance?

    This is a subject that really gets people confused. If a balance reads in 0.001 g (milligram) , then why did the manufacturers put “Minimum Load” on the data sheet at several milligrams. Why not a milligram?

  10. Archimedes' Principle and Density Determination

    Archimedes' Principle and Density Determination

    Archimedes’ Principle aids in the determination of density by providing a convenient and accurate method for determining the volume of an irregularly shaped object, like a rock. This method is quite commonly used in the construction industry. It is known also as Hydrostatic Weighing.
