Hardness testers are primarily used to test the characteristics of a newly designed material or hardness testers are used as a quality check to assure that samples of newly developed products made from material such as rubber, steel and metal meet critical hardness standards. Sometimes the samples that need to be tested are too large to be tested using standard testing machines therefore portable hardness testers are becoming more popular when testing larger samples of material.
Portable hardness testers come in various makes and models. These various makes and models usually differ in the materials that they test. They may range in price from a few hundred dollars up to a few thousand dollars based on all of the machines functions. When choosing the right one it is extremely crucial to know the types of materials that you plan on testing. Portable hardness testers are able to test materials like soft films, rubber, lead, steel, soft metals and hard metals. The majority of these testers are primarily used to test metal hardness.
Understanding the various functions of these testers will help when it comes down to choosing which tester is right for you. After planning on which material you will be testing, next is figuring out how much you are willing to pay and how often will you be testing materials. Generally if you don't plan on using the hardness tester that much than a cheaper model with less functions should be all that you really need. The cheaper models are as accurate as the more expensive digital models. The cheaper models do not come with a digital display but they do run on batteries and their results are produced on a scale display. The more expensive models are generally manufactured to be used for commercial purposes, therefore they offer many more functions. These more expensive models will provide the same accurate results as the less expensive models but they are typically a little faster. The more expensive models also have functions to test a larger variety of materials, they also take less time to provide results and some models also come with a small printer to print out your results.
Knowing the materials you need to test and how often you will be testing these materials will play a key role on how much you should spend when choosing the right one. Considering there are so many options out there when purchasing a portable hardness tester it is extremely beneficial to do a little research on which tester is right for you and your needs.
