45MGUltrasonic Thickness Gauge:Easy to operate, sturdy, and reliable in performance
The 45MG instrument is a high-end ultrasonic thickness gauge equipped with various standard measurement features and software options. This uniquely designed instrument is compatible with all Olympus dual crystal and single crystal thickness probes, serving as an innovative machine that combines all solutions in one for almost all thickness measurement applications.
Standard Features
The 45MG instrument, when used with the basic configuration, is an easy-to-understand and learn, user-friendly thickness gauge. Operators can master the most common thickness measurement applications after undergoing basic training. However, once the 45MG instrument is upgraded with optional software options and probes, it becomes an extremely advanced thickness gauge capable of applications that typical entry-level instruments cannot perform. Moreover, most options can be purchased separately at the time of instrument purchase or at a later date as needed.

Measure corrosion on workpieces using a dual crystal probe
A primary application of the 45MG thickness gauge is to measure the remaining thickness of corroded or eroded pipes, fittings, boxes, pressure vessels, ship hulls, and other structures. The most commonly used probe in these applications is the dual crystal probe.
Automated probe identification feature for standard D79X series dual crystal probes
A dual echo warning is issued when dual echoes occur during the calibration process.
Echo-to-echo/penetrating coating options can measure surfaces with paint and coatings
High-Temperature Measurement: Temperatures up to 500 °C
45MG thickness gauge paired with D932 series probes (D790, D790-SM, D790-RL, and D790-SL) is an ideal choice for measuring high-temperature materials (up to 500 ºC) and provides stable thickness readings. The 45MG's zero-point compensation feature enhances accuracy when measuring on high-temperature surfaces by compensating for temperature variations caused by probe delay blocks due to thermal drift.
Penetrating Coating Technology
Measure the actual thickness of metal using a single-bottom surface echo. This technique can separately display the thickness of the metal and the coating. Both thicknesses are adjusted according to their respective correct material sound velocities. Therefore, there is no need to remove the paint layer and coating on the surface to obtain the thickness of the metal. The penetration coating measurement technology utilizes D7906-SM, D7906-RM, and D7908 dual crystal probes.
