Tester

A tester is one of the basic and essential tools for both professional electricians and anyone who has contact with electrical energy and wiring, even at home.

We present you a wide selection of testers, at the lowest prices, with free on-site delivery.

A tester is a device with universal capabilities that is used to measure electrical network parameters. The modern market presents both simple functionality testers and models for professional use.

A tester is a necessary item that shows the level of safety when working with electricity and using it.

With the help of a tester, it is possible to minimize the risk level when using electricity and electrical devices and to benefit from electrical devices as safely as possible.

Which tester is better to buy?

One of the criteria for choosing a tester is the way in which information is transmitted. According to this indicator, devices are divided into analog and digital models. The first ones have an arrow and can also withstand sustained interference.

The digital tester's screen allows for highly accurate reading of parameters, which is one of its important features.

The main functions of the device include measuring the following parameters:

• Voltage;
• Resistance;
• AC and DC power in the network.

Models with these parameters are sufficient for home use. However, more expensive models can be used to determine induction, frequency, capacitance, temperature, and a number of other parameters.

It is also important to pay attention to the permissible values ​​of the measured values. The required range depends on the individual needs of the user.

This parameter also affects the required resolution of the multimeter, which determines the maximum allowable number of counts that will be displayed on the device's screen. The accuracy of the measurement depends on the probability of error of the tester. It is believed that in low-cost devices, the error rate is from 0.025 to 3%.

If the parameters do not require high accuracy, then it is worth purchasing a cheaper model with an error of up to 5%. However, such a tester is not recommended for solving critical professional tasks.

When working with the tester, safety precautions should be taken to avoid personal injury due to high voltage surges or network transients. We recommend that you work with a de-energized circuit and use an isolating protective device.
