AQUALAB TDL 2 Sensor Description：

User's Manual LEGACY Manual

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 completely 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.

Quicker Quality

Thanks to the TDL laser, measuring samples takes less than five minutes-a great difference compared to other instruments that take up to an hour. Save time, without sacrificing accuracy, no matter what ingredients are in your sample with AQUALAB TDL 2.

Easy to Use

Lightning fast results and low maintenance. TDL 2 is as easy to use as it is precise. No moving parts. No calibration required. Measurement-ready in just five minutes.
