Portable Ultrasonic Thickness Meter

The LANDTEK TM-8818 is a portable digital ultrasonic thickness meter designed for non-destructive testing of materials such as glass and PVC. It suits engineers and inspectors in petroleum, shipbuilding, power generation and machine manufacturing who need to check pressure vessels, chemical equipment, boilers and oil storage tanks for thickness and corrosion.

Upgrade From Basic Gauges

This instrument replaces simple mechanical gauges or single-direction tools by adding bidirectional measurement capability. The jump is worth it when you must determine material sound velocity from a known thickness or measure thickness when velocity is known, and when automatic memory of material codes and sound velocity values will speed up repetitive inspections.

Check Setup Before Ordering

Verify that the test materials fall within the meter's measurement range and that a suitable couplant is available for the coupling indication to function. Confirm whether your data-logging workflow requires the USB or RS-232 connection, or the optional Bluetooth output, and ensure your PC software can accept data from the selected interface.

Questions about this item

Does the TM-8818 probe need a coupling medium to measure glass or PVC pipe walls?

Yes, a coupling symbol on the display confirms proper contact; apply a thin layer of gel or oil before placing the transducer on the material surface.

What is the most common mistake when setting up the TM-8818 for a new material?

Users often forget to store the correct sound-velocity value in the automatic memory before measuring, so the meter recalls the previous material code instead.

How often should the TM-8818 transducer be recalibrated or replaced?

The manufacturer rates parts for three years; plan to verify calibration against a reference block annually and replace the probe if coupling indication becomes unreliable.
