Coffee Laboratories At our advanced coffee laboratories, we calibrate our systems and equipment for efficient, accurate results. Our team of coffee techs bar-code each sample. ie ACA Sensory Panel always performs taste tests “blind,” using a three-digit code to ensure objectivity. Moisture meters (for testing moisture % of green coffee) Agtron Meters (for measurement of roast degree) Color Spectrophotometer (for measurement of color) Vacuum Ovens (for moisture loss-by-drying analysis) Analytical Scales (accurate to .0001 grams) Carbon Dioxide Meter (to measure % carbon dioxide of a gas sample) Vacuum Gauge (to measure package and canned coffee vacuum) Dissolved Solids Meters (to determine concentration of ions in solution) Grinders of various models for different applications (to grind roasted whole bean, espresso, or green coffee)
