Will this machine distinguish corrundum from synthetic corrundum? They are close in index values.

No the numbers are the same. Best to know the supplier you buy from. Try testing by rotating and moving the stone off center a little. A synthetic sapphire will read high in the red zone.Good luck.

No. It won't. The RI isn't similar, it's the same. Corundum is corundum... only the method of manufacture is different.

I bought this for a friend, and he thinks it's real but I'm honestly not sure if he'd know the difference. You might want to contact the manufacturer and ask them.

No, the index's are also made out of hardened plastic. I don't know the actual material that they use, but I have had several of these units and never had a problem with the case or index breaking. That's just my opinion.

It appears to look like the same dimpler but without seeing it up close I really cannot be sure.

Sorry, I have no idea how you would tell the difference. I purchased mine on Amazon,and I am extremely satisfied with it. I did not even know counterfeit Speck cases wereout there. Perhaps you should ask someone who feels they have a counterfeit case, ask them how they know.

the unit seems to be calibrated at the factory. the cardiologist had us being it to an appointment to compare to the nurses manual reading. it was very close

My daughter-in-law purchased a unit from a medical supplier for about the same $$. She has used mine and thinks it to be almost identical.

I'm looking at the same two as well. Any input would be appreciated.Thanks!

Yes. Without doing a careful comparison, it seems the same. Was there something specific you were concerned about?

I really wouldn't know how to tell the difference. All i know is that mine seems to be decent quality so far.

That was my perception, too, at least until I saw the comparison in Fine Woodworking.Hopefully there will be another user out there who has hands on experience with both who can shed some light on this issue.Thank you, though.

Sorry, not my area of expertise, but if it looks the same, it probably does

No. It is just a viewing-transfer machine. Any correction MAY be done with a computer program. This is a bare bones machine.

no real difference at all, from what i can tell, looks to be 2 different listings for the same product, i will match my price on that tomorrow, thanks

It looks genuine to me and working very well. I cannot tell the difference between the two.

This happened in almost the same fashion for me as well. If you are unsure, I would suggest investing in a microscope to confirm. Upon doing this, the test appeared to be accurate for me.

Also you can check the dimensions of the two machines and see if they're similar
