Refractometer (Automatic Temperature
Compensation & Water Resistant)
MASTER-T series features Automatic
Temperature Compensation, for use
when the Water Resistance feature is
not a priority.
Refractometer (Automatic Temperature

series
MASTER-M series is a good choice
when the Water Resistant feature is
not a priority, and the Temperature
Compensation will be carried out
manually. Economical and uncompro-
mising quality.

If you are measuring hot samples such
as jam and marmalade during the boiling
process, we suggest the use of an
ATAGO model H series.
