Testo Put to the Test

Testo Put to the Test

After extensive research and development work, Testo is launching a range of electrical measuring instruments, a move that sees the company entering previously unfamiliar territory.

Testo did not want to simply launch yet another ‘me too’ instrument to the market, but to provide true added value for the target group. In particular, Testo wants to provide instruments that enable contractors in the fields of heating, ventilation, air conditioning and refrigeration to work more efficiently than with existing measurement solutions. The new instruments are designed to be extremely user-friendly: they are easy and intuitive to use, save many work steps, offer the highest level of safety, and are suitable for many various applications.

The launch encompasses 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 recognises 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 fully retractable clamp mechanism that allows current cables to be grabbed precisely; and two current-voltage testers which fulfil the newest voltage tester standard, and select 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 Automatic Multimeter

The 760 family comprises 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 virtually 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. 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.

Testo 770 Clamp Meter

The three instruments 770 family are suited to current measurement in switching cabinets. One of the two pincer arms can be fully retracted into the instrument. This 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 to this, the Testo 770-3 offers a performance measurement function and can be connected with the Testo Smart Probes App by Bluetooth. In the App, you can display the measurement progression as a graph and document it directly in the report.

Testo 750 Voltage Tester with all-round LED display

The three models in the 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 fibre optics. All three models meet the latest voltage tester standard EN 61243-3:2010 and have a safety specification according to CAT IV. 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 755 Current/Voltage Tester

Both instruments in the 755 current/voltage tester family are said to be 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-energisation, 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 1,000V and special functions, such as the single pole phase testing and rotating magnetic field.

Testo 745 Non-Contact Voltage Tester

The 745 non-contact voltage tester, with a voltage range of up to 1,000V, 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.
