    I believe there are indentation testers that are portable and in my experience they give the best results. Rebound testers and ultrasonic contact impedance testers are indirect techniques, unlike the indentation testers. So, unless you develop your own procedure and standards, converting the test results into HRB or HRC or VPN or BHN may prove to be very much error prone.
