Our company is looking to purchase a portable hardness tester for use around the plant. We will just be using it to verify that our suppliers are supplying us with the hardness they say they are (we have had issues with this in the past). We are not looking for an extremely precise tester, just one that will give us a good idea that the hardness is close to the values quoted. In my quick research I have seen units ranging in the $1000 to $2500 range. Is this what I should expect to pay for a tester that will meet our needs? Also can anyone recommend any specific companies that make and sell a tester that would work well but not be overkill for our situation?
