Testo has extended its expertise moving into the field of electrical measuring instruments with the launch this month of five new products covering 11 models.
Testo products are favoured by technicians for being user-friendly and easy to use. After significant research and development, Testo made the decision to put its own electrical measuring instruments into serial production.
The company's marketing manager, Praj Perera, said the company isn't just entering unfamiliar territory, but also pushing the field forward.
"Our first goal is always to make contractor's lives easier and this new range allows them to carry out their daily measurement tasks more easily, safely and efficiently than ever before," he said.
"What’s more, in contrast to many products currently on the market, these measuring instruments from Testo have many
unique benefits, as well as an excellent price-performance ratio.
"With this range, Testo has all of the instruments required for electrical measurement." Its a busy segment of the market with no shortage of solutions but this didn't deter Testo. "We wanted to offer technology that actually added value," Perera said.
The five new product families include three versions of a digital multimeter, which automatically recognises the measurement
parameters by socket use, which can be more safely operated using function buttons as opposed to a rotary dial.
There are 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 µA range as well as an integrated temperature adapter for all type K thermocouples.
The testo 770-3 offers a power measurement function, along with Bluetooth connectivity.
testo 755 – the first voltage tester capable of measuring current
The testo 755 current/voltage tester family are the first of their kind: they’re voltage testers able to measure current. Each is also suitable for virtually all daily electrical measuring tasks. Each time they’re 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’re 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.
