Frequently Asked Questions
Q: What does TDS mean in coffee, and why does it matter?
A: TDS (Total Dissolved Solids) measures the percentage of coffee compounds dissolved in your brew. It directly reflects extraction strength and flavor balance. The AIOK AK002KPRO measures TDS from 0–22%, covering everything from light filter coffee to concentrated espresso, helping you dial in your preferred brew profile with precision.
Q: Does the AK002KPRO require calibration before use?
A: Yes, like all precision refractometers, it is recommended to calibrate the AK002KPRO with distilled water before each use session. Simply place a few drops of distilled water on the sensor and zero the reading. The automatic temperature compensation (ATC) then handles temperature-related variation during measurement automatically.
Q: Is the AIOK AK002KPRO suitable for cold brew coffee measurement?
A: Absolutely. Thanks to its automatic temperature compensation feature, the AK002KPRO delivers accurate TDS readings across varying sample temperatures, making it ideal for cold brew concentrates, iced coffee, and hot espresso alike — all within the 0–22% TDS range.
Q: What batteries does the AK002KPRO use?
A: The meter requires 2 × 1.5V batteries (AAA or AA depending on battery compartment — please refer to the included manual). Batteries are not included in the package.
