Mohs' Hardness Test Kit for Industrial Applications

I like that these have a wide range of testing hardness. At first I didn't think it really mattered to have the lower range but after I received them I have used them almost all the time. I think they were priced in the mid range and I think it was a fair price. They are well made and they are definitely worth the money. They are easy to use and so happy I have them.

Best for my application.

es tal cual dice en la descripción es recomendable

I use it to measure the hardness of rocks and geopolymeric concretes

This is a great kit and really has helped me to identify a lot of minerals that I have found, at least within .5 accuracy. Unfortunately, it is the only game in town so you will over pay for it if you want it. This kit should sell for about, maybe, $80.00 tops. However, it does the job and, hopefully over time, I can justify the cost by the amount of use that I get out of it. It did arrive missing a magnet that was supposed to be included. That and the cost caused me to deduct a star from the rating. Hopefully some competition will arrive to get the price down to a more realistic level.

It works well. I use this almost daily. The tips are accurate with their hardness. Definitely recommend

works great. I added black & white streak plates along with other tests items to make it possible to identify rocks and minerals that I have collected over the years. much more accurate than trying to put a hardness kit together from everyday items

When you need them, these are the ones to get. A little pricey, but I figure production is pretty low and mfg costs higher. I have not verified their accuracy yet
