TI-25DLX Ultrasonic wall thickness gauge with data logging and USB interface

Made in the USAThis high-end wall thickness gauge with data logging and USB output provides the user with the same benefits as the TI-25MX  and is perfectly designed for the one-sided measurement of wall thickness and corrosion on all metals, ceramics, glass and most inelastic plastics.The total measurement range is from 0.63 mm to 914.4 mm, depending on the type of material and probe.

The TI-25DLX has a further upgrade with an amazing built-in data memory for 10,000 readings with 250 measurements per stack, with up to 40 separate batches as well as a USB data interface. This gauge even offers the possibility to transfer the measurement data in .csv format to any software program and view it in the free Datacomm data software.

Another important feature of the TI-25DLX is the modus single or full surface scans. In the latter modus you can pass the probe over a wide surface to acquire the minimum determined wall thickness of the entire surface to be measured.

In addition, an integrated calibration function helps to find the right speed of sound when it’s not known beforehand, as TI-25DLX can automatically calculate the speed of sound based on a sample of known material thickness. 8 preset standard materials canbe pre-selected and the user can also set two custom sound velocities in addition to an individual customization of the speed of sound. The default materials list includes: steel 4340, stainless steel 303, sluminum 2024, cast iron, crylic glass, PVC, polystyrene and polyurethane. To ensure highest accuracy, a 2-point calibration offers the user an improvement of linearity between the maximum and minimum values.

The  TI-25DLX wall thickness gauge comes in a sturdy aluminium housing wih a waterproof probe and a IP65 seal to protect against environmental factors and  breakage. The user has also the possibility to lock the gauge's settings and calibrations against accidental changes by simply using the function of pre-settings lock.The whole is rounded up with a 5 year warranty on the gauge.
