HT2055 consists in a power unit and a voltmetric unit, necessary for carrying out step and
contact voltage measurements in industrial electric installations (TN systems, transformer
cabinets) with a rated test current up to 50A.
The two units, synchronized in time and current are capable of providing the correct
value of step and contact voltages consistently with the real current values measured by the
power unit, also taking into consideration the disturbance effects found on the measured
circuit. It is also capable of measuring earth resistance and ground resistivity by the
classical voltammetric method. These measurements can be saved in the internal memory of the
voltmetric unit and downloaded onto the PC through the provided Windows software.
HT revolutionizes the portable instrument market by introducing the new JUPITER. The first
multimeter who incorporates the functions available only in standard electrical safety testers
and professional High-end multimeters.

M71 has been developed to measure earth resistance with 2 wires and 3 wires by voltammetric
method in compliance with standard IEC/EN61557-1.
This device allows carrying out measurements with a wide measuring range (50kΩ) and an
efficient internal automatic compensation of the disturbance effects found on the installations,
and it is provided with an ergonomic design with electronic function selector for quickly
carrying out the tests. The 2-wire method allows carrying out earth measurement by taking
advantage of appropriate external masses as a reference (metal surfaces, tubes, neutral
conductor, etc.), which is particularly useful in private environments where, because of
logistic problems, it is not possible to use the 3-wire method.

T2000 is a professional clamps specially developed to evaluate resistance of earth rods with no
need to disconnect any part of the system (STAKELESS METHOD)
The inner part of the device is made of 2 jaws, one for current reading and the other
for voltage generation. The voltage jaws generate a potential (E) on the loop during resistance
(R) measurement. A current (I) is consequently generated on the loop and is measured by the
current jaws. Based on the value of parameters E and I, the instrument displays the resistance R
value calculated as their ratio. The value measured by the device can be used in case the single
rods do not influence each other. T2000 also measures AC current up to 20A and leakage current
with resolution 0.1mA. This device complies with standard IEC/EN61010-1 in CAT IV 300V, CAT III
600V and it is the ideal solution for measurements to be carried out both in private and in
industrial environments.

COMBI521EV is the new HT instrument to perform verification and control of electric car charging
stations (EVSE) safety according to IEC / EN 61851-1 and IEC / EN60364-7-722 standards. Being a
combined verification instrument, COMBI521EV also carries out tests on electric systems in
compliance with IEC/EN 61557-1 and therefore measurements of continuity of the protection cable,
insulation resistance (with calculation of PI and DAR), overall earth resistance, RCDs type B, A
and AC tripping time and current, line / fault impedance with calculation of prospective short
circuit / fault current, phase sequence and conformity. COMBI521EV also allows measuring and
saving environmental parameters (illuminance, temperature), leakage current and electric
quantities such as voltage, current, power factor, power and harmonics on single-phase systems.
COMBI521EV is provided with the innovative AUTO function: by selecting this function and only
setting the value of RCD current, COMBI521 carries out tests of overall earth resistance, RCD
tripping time and insulation resistance in a sequence. At the end of the test, the device shows
all results with the indication of compliance or non-compliance with the standards with simple
OK or NOT OK symbols.
The internal memory allows saving the measures and subsequently transfer them onto the
PC through the optical/USB connection. Thanks to the brand new HTAnalysis App, free to download
for iOS and Android systems, COMBI521EV is capable of transferring measured and recorded data
onto tablets and smartphones, thus giving the operator the possibility to customize and share
through HTCloud the result of their tests.
