AQUALAB TDL Water Activity Meter User Guide
AQUALAB TDL QUICK START
Preparation
Inspect and verify that all AQUALAB TDL components arrived in good condition.
Select a clean, level location where the temperature is stable. Locations with high temperature variability (e.g., next to air conditioners, heater vents, or open windows) can affect the accuracy of readings.
Maintenance
The accuracy of the AQUALAB TDL should be verified at least once per shift. If the verification standards read out of specification, the instrument needs to be cleaned.
For detailed instructions on how to verify and clean the AQUALAB TDL, visit metergroup.com/certification or consult the AQUALAB TDL User Manual (metergroup.com/tdl-support).
To reduce the chance of the sample material contaminating the measurement chamber, keep the AQUALAB TDL on a level surface at all times. Do not move the instrument while a sample is loaded into the chamber.
For more information on preventing contamination, visit metergroup.com/certification or consult the AQUALAB TDL User Manual.
