1983, HT was born. During its first years the company has been mainly focusing on selecting and marketing test equipment, clamp-on meters and DMMs. HT aimed at taking the most important challenge: designing and building its own instruments as a result of experiences and ideas gained over the years. The first model MASTER HT2031 was created.


Scissors by HT have been designed to meet the requirements of installation technicians who use these tools not only for cutting but also for peeling and crimping.
