Description

AQUALAB TDL 2

Precise water activity data for even the most volatile samples.

Laser precision

TDL uses a laser beam (tunable laser diode) less than one nanometer wide, tuned to the absorption band of water. It measures water molecules no matter the concentration of volatiles—even soy sauce, gasoline, and tobacco. Readings are so precise, you can even measure water activity in pure alcohol.

Respected by customers and third-party scientists alike, the TDL (tunable laser diode) delivers readings you can trust no matter what the sample contains.

All-around accuracy

Sauces, spices, tobacco, and other volatile samples, are known to be difficult to read accurately—TDL can measure even the most challenging volatiles. The Cooperation Centre for Scientific Research Relative to Tobacco (CORESTA) specifies the TDL as the only sensor for accurate water activity in tobacco products.

The secret to the AQUALAB TDL 2’s precision is in its unique laser technology. The laser beam—less than one nanometer wide—locks on to water molecules no matter the concentration of volatiles. Its sensor has no moving parts and is housed in a fully sealed sample chamber.
