More info

The Starr LHT Series has been designed with ultimate portability in mind, whilst retaining important functions and features that ensure this is a complete hardness tester solution.

The LHT Series features automatic detection of test direction, switchable display, internal memory for 500 readings, one-touch printing to 2.4G wireless printer and simple, one-hand test operation packing a punch for just 147 x 35 x 22mm size. The test data can be reviewed and transferred to your PC via the included USB cable for report writing and closer assessment.

Using the LEEB rebound method, a hardness value is calculated from the energy loss of a specified impact body after impacting on a test surface; the results are directly convertible to common scales such as HRC, HRB, HB, HV very accurately (+/- 6HLD). 

The LHT Series comes as a basic kit with the handheld testing device, USB cable (charger and data), cleaning brush, software CD-ROM and factory calibration certificate. From there you can add on a wireless printer or a Calibration reference hardness block at a discounted price or bundle both in the "Complete kit" for the best value!

Just select your preferred option from the drop down box and add to your cart to purchase.

There are different types of impact devices for various testing environments and applications as follows:


The LHT-D uses a standard D-type impact device. The D-type impact device is for general purpose and suits testing samples with greater than 5mm in thickness. Common applications are hardness testing aluminium heads in automotive applications; excavator buckets and booms in mining machinery, and many other industrial equipment and components. Measurement range: 170 ~ 900 HLD (20 ~ 68 HRC; 13 ~ 101 HRB; 19 ~ 655 HB; 80 ~ 955 HV; 32 ~100 HSD) Available here online.


For lightweight or thin test samples greater than 1mm thickness and surface hardened layers, select the LHT-C which employs a lightweight impact device and lower impact test force. Good for use testing thin steel and aluminium sheet or tube components. It is important to securely clamp or 'couple' the test piece to ensure there is no impact absorption from vibration which can produce low, inaccurate readings. Available here online.


The stumpy DC-type stands only 80mm tall in total. This little nugget can squeeze into all kinds of unusual spaces to test hardness. Think inside bore of pipes, edges of i-beam steel girders, chassis rails and similar. Fitted with standard D-type indenter it has a wide measuring range suitable for testing most common metals. Contact us to purchase.


Long-nose DL-type is for narrow grooves or channels such as o-ring seats, gear teeth and other recessed. The needle point tip is long and extremely skinny (6mm) to allow comfortable access into most hard-to-reach surfaces. A special extended D-type impact device means testing from 20.6 ~ 68.2 HRC is possible. Contact us to puchase.


Is specific for use on very large, rough samples such as ductile iron castings. Measurement range: 300 ~ 750 HLG (127 ~ 364 Brinell) Contact us to purchase.
