HMV-G Series Microhardness Testers & Microhardness Testing Systems

The HMV-G Series microhardness tester is designed for measuring the hardness of small parts and metallic structures used in precision equipment, processed surface layers, and metal plating layers.  The HMV-G Series is ideal for metallographic research and product quality control. It features an intuitive LCD touch screen operator interface combined with an excellent optical system with a minimum unit of diagonal length measurement of 0.01 µm for extremely high accuracy.  

The HMV-G features a truly unique design based around its “G” style frame from which the tester gets its name. The HMV-G incorporates an easy to read digital display with touch screen technology for convenient programming and easy access to all levels of operation. Its bold LCD display is large enough to view test results and on screen graphics such as histograms and data plots, while it’s built-in statistical software accommodates up to 999 data points. A 100 mm vertical capacity and an “unlimited” horizontal capacity on both the X & Y axis, together with a load range from 10 to 2000 grams and fully automatic load change standard, are just a few of the great features of the HMV-G. A fully motorized turret to switch between indenter and objective positions is also available in the model HMV20DT.

The design provides for an expanded work area with open access on both the X and Y planes and allows testing of large samples as well as samples with unusual geometries which cannot be accessed with conventional tester designs. The HMV-G utilizes an extremely precise electromagnetic force control system and allows for automatic and seamless changes between each of the HMV-G’s ten test loads. The HMV-G’s motorized turret incorporates two indenter positions as well as capacity for up to four separate objectives, with 10X and 40X objectives included as standard. Completely integral video camera eliminates the normally bulky camera protrusion and a reliable LED illumination system makes the HMVG ideally suited for integration into automated systems.
Features & Benefits
  • Automatic Load Changing
    Test loads from 10g to 2000g may be configured.  Set dwell times from 5 to 999 seconds. 
  • Excellent Measurement Accuracy
    The minimum length of diagonal measurement is 0.01 µm.
  • Multiple Testing Modes
    Perform standard tests based on a load and dwell time. Or perform serial testing on a batch of multiple impressions.

Our Concept is to provide high-quality industry-specific design services even under the tightest budgets, deadlines, and we continually invest not only in new technologies, but also in our creative talent..
