The best HT instruments for daily use in the commercial and residential sphere 40 YEARS MARKING OUT SUCCESSFUL LINES Research & Development An office, the throbbing heart of HT Italia, a touchstone for every business strategy, the starting point of every new creation, tasked with supporting ideas and converting them into innovative, high-performance instruments. A perpetual fire that fuels a continuously evolving company, a present-day that is invariably also the future. Head office 3.8OO square metres The warehouse 15.OOO cubic metres Italian sales network 15 AGENCIES 65 REGIONAL SALES AGENTS 5 AREA MANAGERS Calibrations and repairs For over 25 years, HT ITALIA has designed and built all circuit Testing and Analysis equipment inhouse, allowing it to provide highly skilled technical support. Today, with a view to providing an increasingly efficient service in line with Client expectations and thanks to an agreement with TRESCAL, HT ITALIA hosts its own separate, climate-controlled laboratory for the issue of Calibration Reports in accordance with ISO 9001, as well as Accredited Certificates (ACCREDIA) in accordance with ISO/ IEC 17025. Distributors 186 Foreign sales network 7O DISTRIBUTORS Manned points of sale 116O 3 REGIONAL MANAGERS 2 EUROPEAN BRANCHES Catalogued measuring instruments more than 68O 2 STORYTELLING Concern and consideration for doing things right, a wealth of experience acquired over the years, an innate sense for innovation, a Future-oriented project cultivated day by day have all made HT Italia one of the most important and exemplary companies in the Market for electrical measuring instruments and a key point of reference for those, who, over time, have wanted or needed to approach this world from which they demand only the very best. Putting forward our expertise, managing and transforming it into exclusive, high-performance instruments, catering to every specific need, is the challenge that has guided HT for more than 40 years and a means of addressing change, investing in the skills and trust of an increasingly demanding and evolved target market. A modus operandi ensuring the added value of a continuously evolving organisation. Latest-generation technology, state-of-the-art infrastructure, unique industry expertise, people, a team, the backbone that year after year, has guaranteed our success and allowed continuous growth on a global scale, from every point of view. Certifications Certified laboratory LAT174 of TRESCAL MS at the HT-Italia head office 3 SAFETY FIRST Electrical measuring instruments, prior still to fulfilling their purpose, must consider operator safety as a basic requirement in terms of protection against temporary overvoltages that may arise due to the presence of complex electrical loads, shortcircuit situations, lightening strikes, etc. To this end, the international standard IEC 610101, harmonised in Europe as EN 61010-1, has set out specific requirements that must be satisfied by electrical equipment designed for LV measurements (<1000VAC), creating four "Overvoltage Categories" that define the level of protection against the voltage transients of each instrument, depending on its distance from the power source. Instruments belonging to the highest category require greater internal protection insofar as they can operate close to the source. A short description is provided below: CAT I CAT II CAT III CAT IV 4 TYPE OF MEASUREMENT Measurements on circuits not directly connected to the distribution network APPLICATION Protected electronic equipment, measurements not derived from mains Measurements on circuits directly connected to the low-voltage installation Measurements on installations inside buildings Measurements on a source of a low-voltage installation Household appliances, hand-held tools and the like Distribution panels, cable harnesses, switches, fixed installation sockets, electric motors, industrial equip. Electricity meters, measurements on primary overcurrent protection devices, ripple control units TEST INSTRUMENTS HTPRO - COMMERCIAL & RESIDENTIAL ELECTRICAL INSTALLATIONS In residential installations, the CEI 64-8 standard requires certain checks in order to certify that the installation has been developed in a workmanlike manner. In addition to the usual voltage and current testers, HT ITALIA also offers simple, portable instruments for classic ground, RCD and insulation measurements. JUPITER / M75L / EASYTEST HT ITALIA's Jupiter, a long-time leader in multifunctional system testing, is a revolutionary multimeter able to test 30 mA RCDs and perform earth tests, that is, carry out the essential checks required for all residential installations. The M75L model also includes insulation testing up to 500V, while EASYTEST can effectively carry out all the necessary 64-8 tests, including the possibility to save the results and generate a report via the supplied software. STARTERKIT A single kit complete with a current clamp and digital tester for measuring the typical parameters in these types of electrical installations, specifically voltage, current and resistance. HT20: portable voltage tester. HT77C: RCDs suddenly tripping due to leakage currents is a common occurrence. This instrument is able to measure these very small currents and get to the root cause, which are often household appliances with insulation problems.
