Tips & Advice to help you make your decision on Metal Roughness Testers

Metal roughness testers are sometimes referred to as profilometers; they are designed to test the texture of the surface of metal objects. When deciding on the type of tester you need to invest in for your company, consider the average amount of time each tester is supposed to take when showing results. It will slow your production down if a handheld analyzer takes a considerable amount of time.

Gaging.com offers a wide selection of portable testers to choose from. Each tester varies in quality and ability, and each can be used for various applications. These testers determine surfaces in Ra, Rq (RMS), Rt and/or Rz.

Newco Inc. is another company that offers a selection of roughness testers. These measure the texture of your metal surface with four roughness parameters. Some testers feature a built-in probe for convenience, while others offer the full range of roughness averages (Ra).

Advanced Test Equipment Rentals offers metal testers for rental. The unit this company rents features a large LCD screen so you can read the measurements clearly, a carrying case for safe transport and 19 parameters for advanced measuring.

Metal Roughness Testers

Find a portable metal surface tester or metal hardness tester suitable for your business

Technology continues to advance the quality, features and user friendliness of testers measuring hardness and roughness of metals. Portable and handheld testers contain the ability to measure from any position. LCD screens provide readouts with the push of a button and light weight means easy access anywhere in shop or field. PC software comes with some of the models to use in gathering information, charts and presentations for certifications.

The tester marketplace contains many types of testers, each with specific capabilities. When selecting a new tester for a hardness or metal roughness measurement in shop or field, consider the following:

1. Determine the amount of use/time required for a handheld metal analyzer, from hardly at all (low-end) or most of the time (higher-end), when considering price.

2. Think of the benefits of obtaining both a hardness and a metal roughness tester, especially for production facilities.

3. Look at cost benefits in outsourcing your metal testing requirements.

Buy a portable metal roughness tester with or without PC interface

Some models come with built-in or detachable stylus and English/metric readouts. Optional styluses are available for certain models to measure bores, holes or grooves.

Purchase a portable metal hardness tester

Choose static or impact type testing units with different hardness scales.

Get a hardness and surface roughness test at laboratory service companies

Let professional service companies provide the precise measurements required for your business. Save costs associated with purchasing a metal surface roughness tester or metal hardness tester, maintenance of equipment and hiring additional in-house employees.

Choose hardness or metal roughness testers from the manufacturer

Deal with companies that manufacture and specialize in metallurgical equipment and solutions.
  • Common hardness scales for a handheld metal analyzer include HV (Vickers hardness), HB (Brinell hardness), HRC (Rockwell hardness) and HS (Shore hardness) among others. Each tester's capability determines the type of hardness it measures.
  • A metal surface roughness tester reads waviness (longer wavelength) and roughness (short wavelength).
