Atago 3810 PAL-1 Digital Hand Held Pocket Refractometer, 0.0 - 53.0% Brix Measurement Range

Works great and was priced right. I have over 40 years only had to buy 3 if you take good care they will last around 10 yrs

Digital Refractometer is very accurate. Easy to use buttons, has a display light and fits well in your hand.

Beware!!!! One drop and done! 3rd one and same issue! Every time you press start only works 1 out of 10 times! Loose interior parts loose connections bad design for so much money!

little disappointed this is the second one I bought on here and the back ground light doesn't light up you can still see the read out , I think next time I will buy it direct from the manufacture , More money but life time guarantee,

When compared to optical refractometers the digital Aptos refractometer is great. It is fast to zero with plain tap water. It reads BRIX quickly and readings are consistent. I am an organic farmer and use it for measuring Brix in vegetables and fruits. Highly recommended for the price.

We were having trouble reading our machine tool coolant on the standard refractometers. It was the same color as the background and difficult to see. This solved the problem. It is very accurate. Make sure that you keep the lens spotless as even a small smear will skew the reading. Works great and is very compact and easy to carry.

I am very pleased with this digital refractometer. It is much more accurate compared to the "flap" type and far easier to use and clean. I like the fact it compensates for the temperature which is displayed on the read-out. Well designed and well made.

Absolutely no instructions for the device. Haven’t used it yet and will have to look online for an owners manual. What the heck?
