 Post subject: Jemeter Digital 90 - Manual and documentation help please
PostPosted: Mon Oct 29, 2018 5:52 pm 
Hi Guys!

It has been a long time since I've come here and hope everyone is doing well. I recently acquired a jemeter digital 90. I have never used this before and have no documentation for it. I tried to search around with no luck. I would greatly appreciate it if someone could help here...I realize it is old and it may just end up being another ornament on my desk but would love any help on paperwork - particularly calibration and basics.

Here are some test results of digital refractometers:

Thanks B!

Thanks for the links....I actually had already gone through all of them already. Nothing really details the calibration or things you need to know for working it.

I did see in one of the pics there was an alternate "ri" value chart that seems to have come with it originally but couldn't make out the numbers and names based on the picture.

If you send off a request to Robert, he would most likely let you know the info you seek.
