Refractometer, STD with automatic temperature correction

An alternative to conventional hydrometers which allows you to take original gravity reading with only a few drops of liquid. Perfect for anyone requiring greater precision or doing a smaller batch where a full hydrometer reading would remove too much liquid and introduce too much head space.

Since the refractometer features automatic temperature correction (ATC), gravity readings can be taken easily and accurately throughout the brewing process without having to wait for samples to cool down
