    The AQUALAB TDL 2 meter uses a laser sensor capable of accurately measuring even the most difficult volatiles. It is easy to use and takes only a few minutes to measure any sample - even soy sauce, pure alcohol and gasoline. TDL delivers readings that provide high precis

    The TDL 2 meter uses a laser tuned to the absorption band of water. The laser beam - with a width of less than one nanometer - blocks water molecules regardless of the concentration of volatiles. The TDL is able to correctly measure the water activity of pure alcohol.

    The TDL 2 laser measures most samples in 5 minutes. Compared to other devices that take nearly an hour to read, this results in significant time savings and faster quality measurements, regardless of the components in the sample.

    The kit includes 12 standards, cleaning kit, 50 measuring dishes, USB cable, power cord, user manual and certificate.
