“What if I can’t find what I WANT?

We offer a complete array of weighing equipment for a variety of applications, such as process control, checkweighing, force measurement, torque testing, parts counting, material handling, just to name just a few. Our on-line catalog includes some of our most popular products organized by product categories. If you can’t find what you’re looking for, or need to find out more about any of our products, please contact us toll free @ 1-800-572-2531 or e-mail us at info@johnsonscale.com.

What about service?

We are an authorized distributor for all the products in our on-line catalog, and honor all manufacturers’ warranties, as well as perform out of warranty service. All repairs are performed by state licensed service technicians, following NIST procedures. Calibration certificates are available (for an additional charge), upon request.

What should I do if I think the product does not work properly?

We would suggest contacting us before returning the item for repair/replacement or credit. In many instances, the scale is working fine and the operator needs some pointers. Occasionally, certain environmental conditions (such as temperature, power issues, air currents, scale not level, etc.) may exist that are altering the operation of the equipment. Many times we can solve the problem over the telephone.

In the event that you need to return the item, you must contact us for a return authorization number before shipment. This can be done by telephone. Our service department will respond, by telephone and/or e-mail within 24 hours.

What is NTEP?

The “National Type Evaluation Program “ is the result of the cooperation between National Conference of Weights & Measures, National Institute of Standards and Technology, and State & Local weights and measures officials in determining the acceptability of weighing equipment for commercial uses. NTEP Reviews products voluntarily submitted by manufacturers for type evaluation and approval. A certificate of conformance is issued for products that pass NTEP’s testing criteria. (Most states require NTEP approval for scale products to be used in “legal for trade” applications.)

What is “legal for trade“ and do I need it?

The best way to determine if your application requires a "legal for trade” scale is to ask yourself “Does the amount of money, charged to a customer, depend on the displayed value on a weighing device?” If it does you are most likely required* to have a “legal for trade” scale. (Some examples: price computing, hanging produce scale, shipping scales, parcel post scales, etc.)

*Check your state or local Weight & Measures department for guidelines on specific applications.

How do I know which counting scale is best for me?

First, find a model that meets your capacity and accuracy requirements. Then, look at the features required for your application, such as computer/printer interfacing capability, battery operation, data storage, etc. To determine the correct model, you will to need to know the weight of the lightest component that you wish to count and the weight and dimensions of the heaviest package you will be placing on the scale. (Use our weight conversion chart on our homepage.)

Our scale won’t give accurate counts-why?

Many factors may cause a counting scale to display incorrect counts. Most of the factors are not a result of the scale being defective or out of calibration (although these do occur) they are usually a result of the scale being incorrect for the application or operator error. Ask yourself some simple questions listed below if you are are having difficulty:

  • Are any external sources causing the scale to give varying counts such as a bad power source, fans blowing on the scale, vibrations or extreme temperature changes?
  • Is the scale level?
  • Since counting scales count by determining the average weight of the component being counted, it is important to use a sample size of at least 25 pieces. The larger the sample size the better the count. Although all counting scales will let you use a sample of less than 25, we always recommend using at least 25 pieces as a sample.
  • Are all your operators using the same sample size? Are some using 10 while others 25 or 50? This too will alter your results.

If your still having problems feel free to contact us.

What lab balance is best for my application?

When purchasing a laboratory balance you should always identify your requirements as follows:

  • Determine your capacity and readability.
  • Consider pan size and other important parameters such as an RS-232 interface, below balance weighing, windshield, battery operation, built-in internal calibration, etc.
  • Note the environment where the balance will be placed. A balance that is dust tight or splash proof may be best suited for your application.
  • Make sure that when you purchase a unit that it has all the features you need for your application.
