Making
contractor’s lives easier

There’s no shortage of solutions available
in the electrical measurement market. The reason why Testo wanted to get
involved was to offer a technology with real added value. Testo wants to
provide contractors in the fields of heating, ventilation, air conditioning and
refrigeration the ability to work more efficiently and safely.

The new instruments are user-friendly, easy
and intuitive, safe and suitable for a number of applications.

Five
new product families

Testo is launching five new product
families for electrical measurement of appliances and systems. These include:

  • Three versions of a digital
    multimeter, which automatically recognises the measurement parameters by socket
    use, and which can be more safely operated using function buttons as opposed to
    a rotary dial.
  • Three clamp meter models with a
    unique clamp mechanism for measuring tight-fitting cables – this allows for
    more precise cable grabbing.
  • Two current-voltage testers
    which meet the newest voltage tester standard and select measurement parameters
    automatically and without the danger of confusion.
  • Three voltage testers, equipped
    with an all-round LED display that can be read from any position. There’s also
    a non-contact voltage tester with a filter for high-frequency interference.
  • testo 760 – the first
    automatic multimeter
  • The testo 760 digital multimeter family comprises three
    different models for all important electrical measuring tasks. Dedicated
    function keys replace the traditional dial on all three instruments, which
    allows for easier operation and greater reliability. Measurement parameters are
    now detected automatically via the assignment of the measuring sockets and
    shown by the illumination of the appropriate function keys – incorrect settings
    are now impossible.
  • The testo 760-1 model is
    the standard version for virtually all daily measuring tasks.
  • The testo 760-2 has a
    larger current measurement range – the true root mean square measurement – TRMS
    – and a low-pass filter.
  • The testo 760-3 is the
    highest specification model, including all the features of the previous two. In
    addition, it has a voltage range of up to 1,000 V, along with higher measuring
    ranges for frequency and capacitance.
  • testo 770 – grab cables
    without touching
  • The three instruments in the testo 770 clamp meter family are
    perfect for non-contact current measurement in switching cabinets. One of the
    pincer arms can be fully retracted into the instrument, meaning cables in tight
    switching cabinets can be easily grabbed.
  • The automatic measurement parameter detection also helps to ensure
    reliable work. In the current and voltage area, all three instruments detect
    direct and alternating current and select other parameters such as resistance,
    continuity, diode and capacitance automatically.
  • The testo 770-1 model is
    the standard version for daily measuring tasks, including starting current
    measurement.
  • The testo 770-2 has a A
    rangeas well as an integrated
    temperature adapter for all type K thermocouples.
  • The testo 770-3 offers a
    power measurement function, along with Bluetooth connectivity.

755 – the first voltage tester capable of measuring current

The testo 755 current/voltage tester
family are the first of their kind: they are voltage testers able to measure
current. Each is also suitable for virtually all daily electrical measuring
tasks. Each time they are used, they automatically select the right settings in
order to prevent dangerous incorrect settings.

Both instruments can determine
voltage/de-energisation, for measuring current and resistance, and for
continuity tests. In addition, the integrated flashlight makes it easy to work
in dark environments. Users can also replace the measuring tips, so that the
whole instrument does not need to be replaced in the event of damage.

  • The testo 755-2 model
    features a larger current range of up to 1,000 V as well as additional
    special functions. It features single pole phase testing and a rotating
    magnetic field measurement.

testo
750 – the voltage tester with all-round LED display

The three models in the testo 750
voltage tester family are the first instruments to feature all-round LED
displays. These displays are easy to view from any angle and guarantee ideal
voltage indication thanks to unique fibre optics.

All three models meet the latest voltage
tester standard EN 61243-3:2010 and have a safety specification according to
CAT4. They are also capable of continuity testing and rotating magnetic field
measurement.

  • The testo 750-2 is
    suitable for single pole voltage testing and has a flashlight along with an RC
    trigger function. Vibrating load buttons prevent accidental trigger tests.
  • The testo 750-3 is fitted
    with an LC display to show the current reading.

testo
745 – the non-contact voltage tester with low-pass filter

The testo 745 non-contact voltage
tester features a voltage range of up to 1,000 V and is particularly
well-suited to fast initial checking of any suspected fault sources. Once the
presence of voltage has been determined, the testo 745 gives a warning via
a clear visual and acoustic signal.

In order to improve reliability, the
voltage tester has a filter for high-frequency interference signals and is also
waterproof and dustproof according to IP 67.

With the introduction of these electrical
measuring instruments, Testo now offers portable and stationary measurement
solutions for almost all areas of application from a single provider. The
instruments are available from HVAC/R and electronics retailers.
