Hardness Tester, Durometer Shore Type A 0-100HA, Digital Durometer 0.1HA Resolution, with Large LCD Display for Rubber, Plastic, Tire, Leather, Wax

It seems to work great tested it vs an old mechanical one. Sure beats the pants of paying 15 times as much for a professional one.

Use this for our dirt go kart tires, works well

I used this to check the hardness on potting. This product was worth the price point and worked well. The product was +- 1 perfect accurate.

Picked this up to measure tire hardness on my go-kart, and it works flawlessly. Readings are quick and consistent, which makes it easy to compare sets and dial in performance and check tire life. Sturdy build and comes with a nice case for storage.

Accurate product description, good packing and shipping process.

I am a materials scientest who specializes in adhesives and elastomers, and needed to replace my old dial shore-A tester. I could not believe how inexpensive this Uharbour gage was, especially considering that it comes with its own box. I checked it against my hardness standards and they were within 0.2 hardness of the standard, which was actually better than my $500 gage. The gage is easy to read and zero and I love it!

Review of B0DG8CQ6PR - Uharbour Hardness Tester, Digital Durometer Shore Type D In one of my prior lives I was a gemologist. As a gemologist, I had to identify gemstones. For identifying transparent gemstones, one of the clues was the refractive index (how much the gemstone bent light passing through it). The refractive index is measured by a refractometer. A refractometer is a critically necessary piece of equipment in a gemologist's toolbox. The refractometer didn't tell me want a gemstone was, but more what it wasn't. Identifying a gemstone is a process of elimination. So, in trying to identify plastics, I thought I'd try this Durometer to tell me the Shore-D hardness of plastics, which wouldn't tell me what the plastic is, but what it isn't. In one photo I've taken the Shore-D hardness of its case, which as you see, is 75.5 on the Shore D hardness scale. Not being a materials scientist, I didn't realize that each plastic has such a wide range of hardness due to possible additives. The 75.5 measurement is not as definitive as I had hoped. A materials specialist can probably identify this plastic just by looking at it and feeling it, but I can't. At least not yet... this Shore hardness tester may help with that. For example, 75.5 rules out LDPE (40-50), PTFE (50-65), CPVC (83-90), PET (85-95), PC (90-95), ABS (100), etc. This Shore D hardness tester will help rule out some plastics and narrow the possibilities, just as the refractometer did with gemstones. The manufacture of this device is excellent and its value to be high. It takes a standard 2032 coin cell. The knurled knob on top unscrews to expose what looks like an adjustment, but it mainly provides a solid press point. I consider this to be a great tool in my toolbox.

So first, be sure you understand what you are getting: This is a Shore D meter, so it's for harder materials like tire rubber, leather, and plastics. It is not appropriate for softer rubbers like shoe insoles or soft silicon rubber. Being a shore-D this meter is probably best used with a stand. You will need to press pretty hard when using it by hand to get a reading. The measuring tip is also pretty sharp, so it will leave a indent on anything short of glass. Be sure to read the instructions. They are a bit dense, but have important info. For this meter, you will want to have access to a glass plate to use to check the meter following the instructions. Also be sure to note the minimum thickness for materials you are measuring. If you are getting this for 3D printing, be sure to understand you need at least 6mm of SOLID material to measure. So 100% infill or very thick walls. So keep that in mind if you are printing test coupons for different filaments. From my use so far, the meter is decently accurate with results on known materials close enough to what I expected to be useful. The kit includes instructions, the meter, a spare battery, and a case. Press the button to open the case, it's not a pry-up like many plastic cases use. One grip I do have is that while the meter has a hold button, it doesn't have an auto-hold feature. This would have been nice to have. Reading the meter off-axis is not easy as the LCD isn't the best.
