testo-New Electrical InstrumentsAfter intensive research and development work, Testo AG has now reached its target to provide an all round solution to the HVAC/R sector by introducing first of its own set of electrical measuring instruments. With them, the company tries to provide uniquely different solutions with advanced features to their customers. These intelligent electrical measuring instruments from Testo makes it possible for the users to carry out their daily measurement tasks more easily, safely and efficiently than ever before. In contrast to many products in the market, the measuring instruments from Testo show many differentiating benefits and an excellent price-performance ratio. Added to this is the advantage, that with 12 products, Testo India completes its basket of necessary tools for measuring needs of HVAC/R.

The objective is to make HVAC/R measurements easier.

The market for electrical measuring instruments today already offers a multitude of solutions for many different measurement parameters. This is the reason why Testo did not want to simply launch yet another measuring instrument on to the market, but to provide a real added value for the target group. In particular, Testo wants to provide innovative technology to enable efficient working of HVAC/R sector than with existing measurement solutions. The new instruments are extremely user-friendly: they are easy and intuitive to use, save many work steps, offer the highest level of safety, and are suitable for various applications.

Five product families for all important measurement tasks.

Testo is launching a total of five product families for all important measurements on electrical appliances and systems. These include a digital multimeter in three versions, which automatically recognizes the measurement parameters by socket use, and which can be more safely operated using function buttons than with the usual rotary dial. Three clamp meter models with a unique clamp mechanism for measuring tight-fitting cables. This allows current cables to be grabbed precisely. It is available with two current-voltage testers which fulfil the newest voltage tester standard, and allows selection of measurement parameters automatically and without the danger of confusion. Completing the range are three voltage testers – all equipped with an all-round LED display which can be read from any position – and 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 of three models for all important electrical measuring tasks. Function keys replace the traditional dial on all three instruments, which means easier operation and greater reliability. Incorrect settings are now impossible, because the measurement parameters are detected automatically via the assignment of the measuring sockets and also shown by the illumination of the appropriate function keys. The testo 760-1 model is the standard version for almost all daily measuring tasks. The testo 760-2 is differentiated by a larger current measurement range, the true root mean square measurement – TRMS – and a low-pass filter – for VFD output voltage measurements accurately. The testo 760-3 is the model with the highest specification and, in addition to the features of the other two models; it has a voltage range of up to 1,000 V, along with higher measuring ranges for frequency and capacitance. In addition, µA current measuring range is also available.

testo 770 – grab cables with out touching.

The three instruments in the testo 770 clamp meter family are ideally suited for non-contact current measurement in switching cabinets with a unique feature of inrush current measurement as well. One of the two pincer arms can be fully retracted into the instrument. This unique grab mechanism means that cables in tight switching cabinets can be easily grabbed. The automatic measurement parameter detection also ensures 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 also has a µA range as well as an integrated temperature adapter for all type K thermocouples. In addition, the testo 770-3 offers a power measurement function, along with Bluetooth.

testo 755 – the first voltage tester measuring current.

Both instruments in the testo 755 current/voltage tester family are the first of their kind: voltage testers which meet the latest standard and which can also measure current. This means they are suitable for virtually all daily electrical measuring tasks. Each time they are used they automatically select the right settings and therefore prevent dangerous incorrect settings. Both instruments have all the important functions for determining voltage/de-energization, for measuring current and resistance, as well as for continuity tests. In addition, the integrated flashlight enables dark spots to be illuminated. The measuring tips can be changed easily, so that the whole instrument does not need to be replaced in the event of damage. The testo 755-2 model is differentiated by the larger current range of up to 1,000 V and special functions, such as the single pole phase testing and rotating magnetic field measurement. In addition, it is also certified according to voltage tester standard DIN EN 61243-3:2010.

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

The three models in the testo 750 voltage tester family are the first instruments with an all-round LED display. The display can be seen from any position and guarantees an ideal voltage indication thanks to its 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 have the most important functions for voltage testing, continuity testing and rotating magnetic field measurement. The testo 750-2 is also suitable for single pole voltage testing and has a flashlight along with an RC trigger function. Vibrating load buttons ensure that trigger tests cannot be carried out accidentally. In addition, the testo 750-3 is fitted with an LC display to show the current reading.

testo 745 – the non-contact voltage tester.

The testo 745 non-contact voltage tester with a voltage range of up to 1,000 V is particularly well-suited to fast initial checking of any suspected fault sources. When the presence of voltage is determined, the testo 745 gives a warning via a clear visual and acoustic signal. In order to increase 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 the electrical measuring instruments, Testo now offers portable and stationary measurement solutions for almost all areas of application from one provider for HVAC/R.
