refratometers

hi which refractormeter is best this 1 RHS-10ATC Portable Salinity Refractometer or a aqumedic 1

I use an Aquamedic one. I like it, easy to use and doesn't seem to get uncalibrated very easily. I check mine monthly but haven't needed to recalibrate it yet and I've had it over 2 years now. Have not used any others so can't compare I'm afraid.

I'm editing this cause Ian reminded me I did have to recalibrate once last year - how dare I forget ;)

I use the deltec which looks very similar to the RHS-10ATC right down to the packaging. The deltec seems to work well, stays accurate and is easy to calibrate

Cheers

Ahh - I bought one of the unbranded ones :mad: Save myself about £10 and was told it did not have the AM badge but was the exact same one?? Obviously it is not as I have to calibrate mine every two weeks and it is sometimes out by 5 ppt
