【Limited time Sale】ATAGO Official site - PAL-22S Digital Honey Refractometer,Hand-held Refractometer, Honey Moisture Meter for Beekeeper,for Keeping Safe Moisture, for preventing Fermentation.

I have tested several devices for testing the percentage of water in honey and this is the best.Simple to operate, fast and accurate.Small and light so you can check in hives.

This is my second Atago honey refractometer. (Owned first one for 8 years until temperature measurement became unreliable).It is accurate - I've tested vs traditional calibrated analogue refractometer at 20 degrees C.The main benefits of Atago digital vs analogue types are:1) 0.1% digital resolution vs the analogue scale which gives a more subjective reading2) The key benefit for me is temperature correction; honey coming from my warm room at 32 degrees into extraction room at say 24 degrees requires precise temperature compensation from the refractometer. The Atago PAL-22S does this very well, after a 2 minute or so delay for the device to adjust to the sample temperature. Importantly the Atago locks into an accurate reading - despite sample temperature and room temperature continually varying throughout the honey extraction session. The ATC analogue devices simply do not have this dynamic stability of readings across fluctuating temperatures.3) It is water resistant, so can be easily cleaned.Room for improvement is accuracy which is +/- 0.2% which could be an issue at the higher end where fermentation may be a risk. However, this is certainly no worse than analogue devices. Temperature accuracy of +/- 1 degree also seems a large margin for a modern digital device.Note also that you must wait 2-3 minutes for the device to give a stable reading where temperature of sample and device are different.It is not a cheap instrument, but very good value for money given the high cost of throwing away fermented honey! I record the moisture content from every extractor run, so I have certainty that my stored honey will not ferment.
