Grind Adjustment
The range of grind and accuracy of settings is truly impressive. The Preciso™
has 40 distinct Macro settings to enable grinding from Espresso to French
press, with the simple turn of the hopper.
In addition, the Preciso™ has a secondary Micro adjust lever, which further
divides each of the 40 Macro positions into 11 distinct steps. These steps (10
microns each) enable you to precisely dial in the grind for the perfect shot. The
Preciso's grind range is 200 to 1170 microns.
Efficient Motor
The Preciso™ houses a powerful DC motor that produces more than four times
the output with twice the efficiency of a standard AC motor found in most
grinders in this class. The motor spins at less than one-third the speed, making
it much quieter and lower in pitch. Extremely well-made, the motor is built to
handle long-duty cycles. In addition, it possesses a thermal safety device that
protects the motor from overheating and automatically resets once the motor
cools.
