Coating thickness gauge MiniTest 700

The coating thickness gauges by ElektroPhysik from the MiniTest 700 series rank among the most accurate and versatile coating thickness measuring devices. The highlights of this family of devices are:

  • Sensor integrated digital signal processing (SIDSP) of measurement values
  • All sensors can be connected without cables to the MiniTest 745 device
  • Wear resistant sensors
  • Bluetooth and USB interfaces
  • Graphical menu control
  • Instructions in 20 languages

The device is available in 3 versions:

MiniTest 725: Measuring device with integrated sensor.
MiniTest 735: Sensor connected by cable to the measuring device.
MiniTest 745: The sensor can be optionally plugged into the device (equivalent of an integrated sensor), connected by cable to the device, or connected wireless via Bluetooth to the device.

The MiniTest 700 series devices facilitate non-destructive coating measurement of non-magnetic coatings (paint, synthetic material, chromium etc.) on ferromagnetic substrates (steel) and of insulating coatings (varnish, enamel, synthetic material, anodising aluminium etc.) on conductive substrates (aluminium, copper, austenitic stainless steel).



We have reasserted our position of leadership in the coating thickness gauge market with the SIDSP sensors, an outcome of decades of experience in developing special sensors and the use of state of the art technology. SIDSP stands for "Sensor Integrated Digital Signal Processing", meaning that a special micro processor (DSP) collects, filters and processes measurement values in the sensor head.

  • Above average precision and repeat accuracy
  • Temperature compensation across the entire range
  • Wear-protected, polished sensor poles
  • High immunity to electromagnetic (EMC) interference
  • Internal characteristic curve with up to 50 data points
  • Automatic compensation of the conductive value in the case of non-ferrous metals

Versatile sensors for varied measuring jobs.

We would be happy to provide you with advice to select the right sensor; avail of our offer and call us or send us an email. Together we will determine what is the optimal configuration for you and even gladly assist you subsequently in operating the device. We owe it to our customers to provide consultation and it follows that it is offered free of cost.


Fields of Application

On account of the compact design and multi-functionality of the connectable sensors the device can be used for the most varied measuring jobs:

  • Measurements to be taken on small parts, on thin metal bars or grooves call for our miniature sensors with the world's tiniest measuring tip of 2.5 mm / 0.1".
  • We offer special sensors for auto body measurements with reduced sensitivity to factors relating to the geometry of the component and/or the thickness of the auto body sheet.
  • In aircraft construction, there are different alloys used based on aluminum or titanium -
    our coating thickness gauge automatically compensates for the different conductivities and can measure without recalibration on various non-ferrous substrates.
  • There are special tube sensors to measure grooves, drill holes and spots not easily accessible.
  • In the area of heavy corrosion protection, e.g. in large steel structures (bridges and shipbuilding), large amount of readings are taken on site and evaluated later. Here these instruments often known as paint thickness gauge.
  • The robust heavy duty sensors are meant for use in environs prone to dust and moisture (construction sites, shipyards).
  • When in need of measuring thicker coatings like fireproof coatings or special coatings in pipeline constructions, the F 15 sensors help measure up to 15 mm / 0.59" of coating thickness on steel.
  • A special sensor is available for measurement on heavily abrasive surfaces with high surface roughness.
  • In quality control labs the devices can be connected by USB or Bluetooth to your PC for further processing of measurement data, for e.g. with the CAQ software QUIPSY.


Measurement Modes

  • Single Mode
    In the single mode up to 70 measuring values per minute can be recorded and saved.
  • Continuous Mode
    In the continuous mode up to 20 coating thickness values are calculated per second. In this mode you can for e.g. determine the thinnest or thickest spot and then save the readings in a series of measurements.



Menu-driven operation via graphic interface. Instructions and help texts in 20 languages help you with the settings.

The pre-defined calibration procedures assist you in calibrating as per international standards (ISO, SSPC, etc.).

There is a separate user guidance for measurements on rough surfaces.


Data Transfer

The measurement data saved in the MiniTest 725 / 735 / 745 devices can be transferred by USB or Bluetooth to PCs, tablets or smart phones. You can save up to 10,000 measurement values in the MiniTest 725 and 735, and up to 100,000 measurement values in the MiniTest 745.

This enables you to record measurement values on site and to evaluate and archive them at a later point in time.

The delivery of the device includes the data transfer software MSoft 7 basic. The advanced software MSoft 7 Professional will help you can manage and evaluate the measurement values.


Non-destructive coating thickness measurement of:

  • Non-magnetic coatings like varnishes, enamels, chromium and zinc on ferromagnetic base materials (e.g. steel)
  • Insulating coatings like varnishes and anodising aluminium on nonferrous metals (e.g. aluminium, austenitic stainless steel, brass)


  • Precision in coating thickness measurement of up to 15 mm / 0.59"
  • Increased accuracy and reproducibility by sensor-integrated digital signal processing (SIDSP®)
  • All sensors can be connected without cables to the MiniTest 745 device
  • Universal probes with automatic substrate detection for quick measurements on steel and nonferrous metals
  • Wear resistant probes with virtually unlimited life
  • Storage for 10,000 readings (MiniTest 745: 100,000 readings)
  • Optimal temperature compensation
  • High precision characteristic curves with up to 50 data points in the factory calibration
  • Integrated user guidance in 20 languages
  • USB and Bluetooth interfaces for data transfer to PC, mobile devices or printer
