Works well easy to use - no problem.
I am sorry to have to give a negative scoring but i was asked to give a review,but also i woud not want anybody else to be as dissapointed the refractometer itself is of nice quality with a clear view reading of your results,the problem is that their are absolutely no instructions,thats where the problem lies when you will eventually have to recalibrate,i did contact bee equipment who pointed me in the direction of utube,for instructions,the problem is ther are so many on the market wich all use different types of fluid for recalibrate, so unless you actually know for sure what to use,really your just guessing, i did ask again if they cou find out more from the manufacturer but i have not yet had a reply,for the cost you pay for thus item surly you should get a set of instructions ,so buyer be ware.
Item arrived promptly and in good working order. Very pleased with product.many thanks.
I had assumed that the refractometer was pre-calibrated having read reviews online. If so, this is an excellent product, easy to use, and very clear results. However the item arrived with no instructions at all, so if re-calibration was required, wouldn't know how to do so. Plan to contact Bee Equipment to see if they have instructions. Otherwise, prompt delivery and good service as always.
Excellent product and an excellent company to deal with.
