Selecting and Using Precision Scale Test Weights

Calibrating Scales with Test Weights

Weighing accuracy is a primary criterion for precision scales, analytical balances and moisture analyzers where readout (the smallest weight difference displayed) and linearity (the ± deviation from the actual weight) are governed by GLP, ISO and other standards.  Test weights have a critical role to play when scales  with capacities from milligrams to tons are not automatically internally (see below) calibrated . The type of calibration, whether internal or external, is indicated on scales’ spec sheets.

How to Simplify Liquor Inventory Management

How much remains in all those bottles?

How much remains in all those bottles?

A well-managed bar can often be the difference between profit and loss in a restaurant.  According to a Restaurant Resource Group posting, food and beverage inventory levels being too high relative to corresponding sales is one of 10 restaurant financial red flags.  That post provides some formulas for calculating food and beverage inventory.  Here we describe a liquor inventory management system that can be a major time saver.

Bar Inventory Management Simplified with Stocktaking Scale

Inventory management can be simplified through precision weighing systems.  An example is a scale-based inventory management system to count shipments at the receiving dock, stock in storage and stock shipped out.  Now, with the Kern SMT stock master balance available from Tovatech, keeping track of bar inventory no longer requires restaurant management to rely on eyeballing bottles and guesstimating the number of pours remaining in each.

How Counting Scales Count

A counting scale can tell you how many hex nuts are in the pile.

A counting scale can tell you how many hex nuts are in the pile.

Counting scales are great time savers that also improve the accuracy of counts when the objective is to ship or receive X numbers of widgets. They are also great for inventory management because they allow you to quickly determine how many widgets are in stock and when it is time to order more.

How do Piece Counting Scales Count?

Keep in mind that a piece counting scale can be programmed to determine the count of a number of products that are kept in the scale’s internal memory but each product must be the same. You must separate bolts from nuts, (and lock washers while we’re at it) not combine them unless you are counting assembled nuts, bolts and lock washers. And all bolt, nut and lock washer assemblies being counted must be the same. A counting … Read the rest

Proper Use of Analytical Balances in University Laboratories

Analytical balances are among the most vital pieces of equipment in any modern university laboratory. These delicate instruments display the mass of materials with precision levels as fine as 0.0001 or 0.00001 grams. Students and researchers in fields such as materials analysis and pharmaceutical testing require high precision levels for their experiments. Analytical balances come equipped with transparent enclosures, as even the smallest dust mote or air current can adversely affect the measurements.

Analytical balances are so important to university laboratories that some facilities run daily zoomed-balance-weightscalibrations to be sure that their instruments are delivering accurate results. At the University of Connecticut, a staff member coordinates a verification routine for each balance used in advanced chemistry courses. The school’s chemistry department also arranges for a technical firm to conduct annual inspections of each balance to insure each instrument’s accuracy.

The department also arranges for an “Introductory Balance Talk”, which serves … Read the rest

Practice Makes Perfect: How the Pharmaceutical Industry Uses Precision Scales

kern-pcb-1000-2The primary measure of the effectiveness of a pharmaceutical product is how beneficial it is for the patient, while introducing minimal side effects. A vital part of the pharmaceutical manufacturing process occurs at the quality control stage. A variation of a few milligrams in a powerful drug can mean the difference between a nightmare of side effects, a harmless and ineffective placebo, or a valuable treatment method. The key to ensuring that a “wonder drug” achieves the goals that the developers set out for it is careful measurement via a laboratory scale.

Types of Laboratory Scales
Just as various types of microscopes offer the ability for researchers to see items ranging from bacteria down to molecules, different types of laboratory scales offer the ability to measure items to within very small masses. These scales carry specific names to differentiate their levels of readability:

  • Precision balances vary in resolution and some

Weighing & Measuring – A Critical Function for Most Businesses

Accuracy in a Platform Scale should be maintained with periodic calibration checks.Weighing and Measuring is a critical function in most businesses.  In many instances when the weight or measure impacts a consumer or public service, the business should take extra precautions in ensuring its accuracy.  This is not only from the reputation point of view but also from a regulatory stand point.  Take for example the Weights & Measures Department in Memphis.  They deploy a team of inspectors who inspect the weighing and measuring devices at a variety of businesses.  Dispensers in fuel stations, platform scales in stores, the trip meter in taxis, all come under their purview.  Further, the Department has the power to shut your business down if your weighing and measuring units are incorrect.

Platform Scale Measures Cotton Yield

Use A Digital Platform Scale to Measure Cotton Yields

Use A Digital Platform Scale to Measure Cotton Yields

In this investigation of cotton yields, a platform scale was used to measure the weight of cotton.  The study’s primary purpose was to determine if ultra-narrow row cotton production could yield higher returns for cotton farmers in the Arizona high deserts. The study measured the yields in plant population density of 100,000 plants per acre. Single, double, and quadruple lines per bed was the target.  However, this investigation failed to show yield increases in single or multiple row plantings.
