Electrical Measuring Instruments

When measuring electrical parameters such as current, voltage or resistance, you depend on absolutely reliable measuring instruments. The testo 760-1 hands you a digital multimeter which sets new standards in terms of reliability.

In comparison to standard multimeters on the market, with the testo 760-1 there is no need to first select the measuring sockets and then the measurement function. The instrument detects the appropriate measurement parameter via the socket assignment all on its own – and so rules out any dangerous incorrect settings.

The operation of the multimeter is easier and more modern than ever. The traditional dial is replaced by function keys, enabling you to control the instrument with just one hand. And thanks to the large, illuminated display you can see your readings clearly at a glance. The testo 760-1 has the most important functions for your daily measuring tasks and is therefore the ideal entry-level instrument in the digital multimeter class

Testo 760-2 digital handheld multimeter means you can measure electrical parameters more easily and reliably than ever before. In contrast to other multimeters, the testo 760-2 automatically detects the appropriate measurement parameter via the socket assignment – and therefore rules out any dangerous incorrect settings.

It is not operated conventionally by a dial, but with illuminated function keys. This means you can easily control the measuring instrument with just one hand. The large, illuminated display shows the readings clearly.

The testo 760-2 digital multimeter has the most important functions for measuring current, voltage and resistance. The measurement of current strength is also possible in the µA range thanks to the larger measuring range. And the integrated low-pass filter achieves more accurate measurement results on frequency converter controlled motors.
Temperatures can also be measured with this multimeter in addition to electrical parameters

Testo 760-3 digital multimeter is the multitasker for all important professionals in the electricity sector. It enables you to carry out both simple and demanding electrical measuring tasks more reliably than ever before. The testo 760-3 automatically detects the appropriate measurement parameter via the socket assignment and so prevents dangerous incorrect settings.

A voltage range of up to 1,000 V, a frequency range of up to 30 MHz and capacitance of up to 60,000 µF mean the testo 760-3 multimeter can also be used for industrial applications, such as troubleshooting in large electrical systems. And the integrated low-pass filter achieves more accurate measurement results on frequency converter controlled motors.

Temperatures can also be measured with this multimeter in addition to electrical parameters. You will need the clip-on type K thermocouple adapter and a temperature probe (both items can be ordered separately)

This clamp meter means you can cope in any application environment, no matter how tight. The movable pincer arm can be fully retracted into the instrument, so that you can for instance grab tightly packed cables in switching cabinets as if you were using a hook. You have never been able to measure as conveniently as this in tight spots.

The operation of the testo 770-1 clamp meter is also easier and more reliable than ever before. It automatically detects and selects AC/DC and other electrical parameters, such as resistance, continuity, diode and capacitance. In addition, you can also use it to measure the starting current. And the two-line display presents your readings clearly and distinctly

Testo 770-2 clamp meter makes it so much easier to work on tight measuring points, such as switching cabinets. The clamp meter's movable pincer arm can be fully retracted into the instrument. This means you can accurately grab tightly packed conductors such as cables and check them for faults.

Furthermore, it enables measurement of the starting current on electric motors and ionisation current testing in the µA range. The supplied temperature adapter for thermocouple probes can be used to measure electrical parameters as well as temperatures (compatible type K thermocouple probe can be ordered separately)

The clamp meter detects and selects AC/DC fully automatically and also provides automated selection of other electrical parameters such as resistance, continuity, diode and capacitance. This makes operation easier and more reliable than ever before. Your readings are clearly and distinctly presented on the two-line display

Testo 770-3 clamp meter is the ideal clamp amperemeter for demanding measuring tasks in tight application environments. The movable pincer arm can be fully retracted into the instrument. This enables the instrument to grab tightly packed cables in a particularly accurate way.

In addition, more specialized applications can be handled using the clamp meter, such as starting current, power and µA measurements. The optionally available temperature adapter for thermocouple probes can be used to measure electrical parameters as well as temperatures (compatible type K thermocouple probe can be ordered separately)

The clamp amperemeter automatically detects and selects AC/DC and other parameters, such as resistance, continuity, diode and capacitance,. This makes operation easier and more reliable than ever before. Your readings are clearly and distinctly presented on the two-line display. In addition to this, the testo 770-3 offers a performance measurement function and can be connected via Bluetooth to the testo Smart Probes App. In the App, the measurement curve can be displayed as a graph on your smartphone/tablet and directly documented in the report

The first voltage tester with current measurement is here: the testo 755-1. You can test electrical circuits or systems for voltage or de-energization, measure flow of current or current consumption and carry out continuity tests using a single instrument. In the process, the testo 755-1 voltage tester detects and selects all the electrical parameters automatically: you can just start measuring – without any switching on or selection.

The measuring tips, which can be quickly and simply exchanged, are also particularly user-friendly. This means you do not need to replace the whole instrument straight away in the event of damage. Just as practical: the integrated torch for illuminating dark measuring points.

The testo 755-1 current/voltage tester is a genuine allrounder which will make your day-to-day work easier

With the testo 755-2, you are equipped for the most important tasks of the working day. The current/voltage tester is suitable for determining voltage or de-energization, checks voltage level and continuity and measures flow of current along with current consumption. It is a simple task to change faulty measuring tips – without needing to replace the instrument. And the automatic measurement parameter detection and integrated torch make operation and measurement particularly easy and reliable.

Compared to the testo 755-1, the testo 755-2 has an increased voltage range of up to 1,000 V and enables rotating magnetic field measurement along with single pole voltage testing to determine quickly whether conductors are live

In contrast to the standard voltage testers on the market, the testo 750-1 voltage tester has an extremely practical all-round LED display which can easily be seen in every work position and from any location. In addition, large fibre-optic illuminators show the presence of voltage clearly and distinctly. The deep-seated anti-slip ring, the ergonomic shape of the handle and the robust housing provide greater comfort when working. The robust design means the voltage tester is durable and reliable, even when used intensively.
