Roast Meter USB-C

Intended use of Roast Meter

• The Roast Meter is intended to be used by casual coffee roasters and coffee consumers to evaluate the color of their coffee for quality purposes.
• The Roast Meter replaces the use of roast color cards and out-dated roast descriptors with something more quantifiable that can be shared with others.
• It allows you to make a color evaluation with only 4-5 beans, making it great for sample roaster where the total amount of beans is limited.

Limitations

• While the Roast Meter achieves good alignment with reference meters, it is not intended for use in applications requiring high accuracy and precision, such as in a commercial environment.
• The Roast Meter is not designed to replace a calibrated reference meter, such as a LightTells, Agtron or Roastrite.
• No guarantee is made for the accuracy of the readings from the Roast Meter against reference standards.
• This model needs (not included) an USB-C cable and a phone charger to work. This is not the lithium battery version.
