Precise water activity data for even the most volatile samples. Volatility meets precision. Achieve accurate water activity readings in samples with volatile compounds. 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. 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.
