電流/電圧テスター755比較

The electrical tester measures voltage or current and it is suitable for both AC and DC voltage. As a multimeter it also determines other measurement data, in addition to the exact level of voltage. Automatic detection means the instrument is suitable for virtually all daily electrical measuring tasks, without the need for any switching.

The current tester for important measurements

The measuring instruments generally have exchangeable measuring tips. An integrated light also means unfavourable light conditions are not a problem, as the light shows the measurement results clearly.

The classic electrical tester enables the following measuring tasks to be carried out: 

  • checking electrical systems for a specific voltage or the absence of voltage,
  • measuring current,
  • carrying out continuity testing.

Testing current safely – with the right instruments

A variety of instruments can be used to test current or voltage. A professional voltage tester not only enables you to get information about the presence of a voltage, but also to determine the resistance and other measuring values.

When deciding on an electrical tester, you have the following products to choose from: 

With the two-pole voltage tester you get an instrument that provides particularly precise measurement data. The two test electrodes are permanently fixed onto the measuring instrument. This control unit has an easily visible display and its ergonomic shape makes it easy to hold securely. In order to protect the voltage tester and the user, the instrument is equipped with a variety of series resistors. In order to carry out a measurement, you touch two different cables or other potentials with the test electrodes. You then read out the latest voltage values on the display.

Current testers from Testo – for your safe use

Testo current testers are characterized by reliable measurement and voltage display, even when the battery is empty. The instruments do not have to be switched on specially and work without any pre-selection. The measuring instruments bear the appropriate seals of approval for safety.

If necessary, you simply replace the measuring tips to ensure you can then continue to test the current safely. The electrical tester carries out an automatic detection of the electrical parameters, which means no separate selection is needed.

Testo has two current testers available for you, which both provide a reliable result and impress with their versatile capability:

  • the testo 755-1 current/voltage tester, with batteries, measuring tips and measuring tip caps,
  • the testo 755-2 with a larger voltage range up to 1000 volts.

The electrical tester for precision measurement

In comparison to other voltage measuring instruments, the two-pole test instruments impress with their multi-functional capability and their accurate results. There are measurement categories for voltage testers which are intended to ensure optimum personal protection. CAT III two-pole voltage testers are reliably protected against overvoltage and therefore also withstand a short circuit.

Testo's voltage testers are very convenient and safe to operate, thanks to their handy size and a weight of 320 grammes. They are suitable for an operating temperature of between -10 and +50 degrees Celsius and have protection class IP64.

The following technical data apply to both Testo's current testers: 

  • the measuring range is 6 to 600 V or 6 to 1000 V, depending on the instrument,
  • the resolution is 0.1 V,
  • the precision for AC and DC is ± 1.5% of measured value + 3 digits.

Testing currents: what you need to keep in mind

Testing currents: what you need to keep in mind You always operate the voltage testers with two hands, which means you avoid accidentally touching the test electrodes which are energized. In addition, the test instruments meet the strict safety requirements and bear the CSA and CE seals.

Before you test the voltage, a function test is worthwhile. To do this, you hold the instrument on a current source that is already known and check whether the display is correct. The following help you both with this process and with the actual current testing:

  • measuring point illumination by LED,
  • digital display.
