MiniTest 735 Precision measuring instrument

SIDSP – The best you can get in the field of measurement technology

SIDSP stands for “Sensor Integrated Digital Signal Processing”, meaning that a special microprocessor (DSP) collects, filters and processes measurement values in the sensor head. The benefits of this measurement technology for your application are as follows:

• Above average precision and repeatability
• Temperature compensation over the entire range of measurement
• Wear-resistant, polished probe poles made of carbide metal
• High immunity to electromagnetic (EMC) interference
• Measurement range up to a coating thickness of 35mm
• Each sensor individually factory-calibrated
• Automatic compensation of the conductive value for non-ferrous metals

With our decades of experience in the development of coating thickness gauges and specialised sensors, as well the application of the newest technologies, our SIDSP sensors make us a market leader in the field of non-destructive coating thickness measurement.

A diverse range of applications from a wide variety of sensors

The compact design and the variety of sensor attachments means that the coating thickness gauges MiniTest 725 / 735 / 745 can be used for the most varied measurement tasks:

• Measurement of small parts, thin metal bars or in grooves: ease of use due to miniature sensors with the world’s smallest measuring head (diameter: 2.5mm).
• Automotive bodywork: the specialist sensors have reduced sensitivity to geometric factors and the thickness of bodywork panels.
• Aircraft construction: particularly challenging variety alloys based on aluminium or titanium are no problem for the MiniTest 700 since it automatically compensates for varying conductivity and can take readings on different non-ferrous substrates without the need for re-calibration.
• Measurements in holes and hard-to-reach places: attach one of the specialised tube sensors and it’s ready to go!
• Corrosion protection, e.g. in large steel structures (bridge construction and ship building): the devices in the MiniTest 700 series can record high volumes of readings in situ that can be analysed later.
• Environments prone to high levels of dust and moisture (construction sites, shipyards, etc.): heavy duty sensors are equipped with particularly robust measuring heads that can easily withstand different environmental conditions.
• Thicker coatings, e.g. fireproof coatings or special coatings in pipeline construction: the F 15 sensor allows you to measure up to 15mm coating thickness on steel.
• Measurement on highly abrasive surfaces with high roughness depth: specialised sensors also available.

The MiniTest 700 is therefore capable of overcoming almost any task in measuring coating thickness!

Simple and comfortable operation – as equally important as precision readings!

When developing the MiniTest 700 series, we attached great importance not only to making sure that you can take precise measurements, but also to making the device extremely easy to use.

The device is operated using a menu on a graphic display. Instructions and help text in 20 languages guide you through the settings. Predefined calibration processes help you to calibrate according to international standards (ISO, SSPC, etc.). And a special measurement mode is available to optimise measurement on abrasive surfaces.

Data transfer is equally simple and convenient. You can transfer readings saved on the MiniTest 725/735/745 devices with complete ease to PCs, tablets or smartphones using a USB or Bluetooth connection. You can save up to 10,000 readings on the MiniTest 725 and 735 devices and up to 100,000 on the MiniTest 745.

This gives you the option to record readings on site that you can then analyse and archive at a later date.

The delivery of the device includes the data transfer software MSoft 7 basic. And for detailed analysis, the software can be upgraded to MSoft 7 professional.
