DatasheetThe MiniTest 400 is available in three variants:
- MiniTest 420 – the sturdy entry-level model with the most important basic functions
- MiniTest 430 – with an extended range of functions and a USB interface
- MiniTest 440 – the high-end device that can also take measurements by penetrating coatings
The intelligent ultrasonic test probes are recognised automatically by the device. Recalibration is therefore unnecessary when switching probes.
You can scan an item continually for thin areas in minimum mode.
MiniTest 420
Sturdy and economically priced basic model with memory, USB interface and automatic probe-calibration detection. Standard and minimum measurement modes are available.
MiniTest 430
With integrated memory for 10 groups each with maximum 500 measuring values and USB interface. Besides the MiniTest 420 model, the differential, alarm and scanning measuring modes are also available.
MiniTest 440
High-end device with integrated memory for 10 groups each with a maximum capacity of 500 measuring values, USB interface and 5 measuring modes; connecting echo-echo probes is possible.
Application
Non-destructive wall thickness measurement of::
- Hard materials like metal, synthetic material, glass, ceramic etc.
- Hollow bodies of all kinds like tanks, pipes etc.
Measuring modes
Standard The standard mode displays the active measurement reading. Minimum The lowest measured value (= thinnest point) is displayed while measuring. This mode is suited for measurement on curved surfaces or to locate the thinnest wall thickness. Differential Shows the differential value between the required thickness and the effective thickness measured. Alarm (Limit) Activates an optical and acoustic alarm when values exceed or fall short of the threshold values. Scan Particularly for quick measurements at high material temperatures.
