Will this work for testing epoxy resin hardness?

Hi, this type A durometer is used to measure the hardness of rubber and plastics. It is applicable to test the penetration medium hardness of rubber, plastic, leather, multi-grease, wax, etc. So it might be not suitable for epoxy resin.

Can i test metals with this?

I highly doubt it! It's for testing density/hardness of tires not metal. You more than likely will get the same reading on all metals. It's intended for rubber!

Can this be used on silicone that is less than 6mm but is attached to 15mm stainless steel?

Hi, it can be used to test the silicone that is attached to 15mm stainless steel, but the minimum thickness of silicone must be at least 5mm.

Can this tester be calibrated?

You can buy test blocks for calibration. Just search "Shore A Test Blocks"

Works great, zeros and reads easily!

I am an adhesives engineer and often need to measure the hardness of soft things like rubber or foam. The Gain Express Shore A tester is everything I could hope for:1) It comes with a nice protective case for travel and transportation2) It is powered by a common size watch battery3) It zeros easily and stays zeroed for a long time4) It is highly repeatable compared to the old analog testersI spent the last week testing cast urethane rubbers which are somewhere between 50 and 80 A hardness, and it clearly helped me identify undercured material. The tool saved me a bunch of analysis time and was a bargain price, considering how nice it is.

Accuracy unknown

Seems to work but I question just how accurate it really is.

Fast, accurate, and cheap!

Agrees nicely with a traditional analogue dial durometer. Verified against durometer test blocks and results were very accurate till around 40A, below that accuracy was still good enough. Nice fast readings, viewing angle for the LCD kind of sucks though.

Surprisingly accurate

Bought this as a quick comparison and quality check on some plastic parts I make for sports use. I have been using a very high tech tester at work and this is within +/- 2 from it. For the price this thing is much better than I ever expected.
