Sophisticated design, excellent usability.
Evolution of the long-selling microhardness tester FM series.

The front panel is the same touch panel type as the LX series and has a variety of functions.
D1 and D2 measurements are digital measurements. With data output function.
Equipped with a hardness conversion function.
At the time of HV measurement, the conversion value to any scale can be displayed on the front panel at the same time .

Test force by weight

Evolution of the long term seller, weight type Microhardness tester.

tilted turret

Tilted turret

By adopting a tilted turret, the turret rotation reduces the risk of contact bewteen the sample and the indenter/objective lens.

Infinity lens

In addition to the standard 2 lenses (×10 and ×50), up to 5 can be installed at the same time. (option)
A wider range of measurement and observation is possible from low magnification to high magnification.

Dual indenters

Standard 1 | Vickers indenter (HV)
Option 1 | Vickers (HV) / Knoop (HK) / Brinell (HB)
Total 2 pieces of different indenter can be installed.

Capacitive touch panel

Capacitive touch panel

The main display screen can be switched by swiping.
Capacitive touch panel realizes light touch operation.
Measured data can be transferred directly by connecting to a PC from the output port of the main unit. Eliminates recording mistakes by operators.



Next-Generation Microhardness Tester.
Built-in camera with an automatic indentation reading.

Best performance and larger field of view is guaranteed and the high-resolution camera and dedicated software is equipped as standard.
The indentation is displayed on the PC/tablet and automatically measured.
Significantly reduces the burden on operators and individual differences in reading.

Dedicated software ARGO main screen

“ARGO” software main screen

Various data output such as PDF is now possible.
Access is restricted by operators' ID and password.
In addition, no complicated setup of conventional software is required.
Anyone can easily perform measurements without the need of complicated settings.

  • ①:Measurement results, D1 & D2, conversion values for each scale etc. are displayed.
  • ②:Displays the most recent measurement results in a list.
  • ③:Various operations can be carried out for the operators to operate easily.
    • Items are displayed with easy-to-understand illustrated icons.
    • For load application & reading, lens selection, indenter selection, setting change of various species, data and image save & recall, it became possible to smoothly create report, etc.
  • ④:Live/saved image display screen.
    • The use of a high-resolution camera improves operator visibility and measurement accuracy. Indentations on rough surfaces, which were previously difficult to read, can now be read in many cases.
    • By making the aspect ratio almost 1:1, it is possible to display and measure wide indentations.
