Choosing the right socket tester just got easier

It is fair to say that when it comes to a first line of defence in electrical safety, socket testers are a great way of keeping anyone working with electricity safe.

Consequently, there are a huge variety of socket testers on the market and it can be difficult to choose which one is best suited to the application you are working on.

All socket testers will check basic connections have been made correctly, however three new Martindale Electric socket testers give professionals more features and less headaches when it comes to choosing the right unit for the job in hand.

Martindale Electric’s BZ701, for example, not only detects the basic 28 socket wiring fault conditions and checks the mains voltage level, it also safely detects Line-Neutral reversal (cross polarity) at the incoming supply. The polarity swap test detects fault conditions on PME/ TN-C-S systems (the most common type of supply) that cannot be identified by normal socket testers. It is easily activated by using the touch pad on the BZ701. Correct polarity is indicated by three flashing green LEDs. A fault condition is clearly indicated by three red LEDs and a warning buzzer.

The recently launched EZ165 and EZ365 also detect the 28 basic fault conditions and check the mains voltage level too. Both models also show how safe the earth wiring is by carrying out a non-trip earth loop test and indicating its value in six discrete ranges. A low earth resistance is essential for safety disconnection devices to work properly and prevent electrocution when faults occur.

In addition to all the features of the basic EZ165 model, the EZ365 not only checks for L-NE polarity swap at the incoming supply as featured on the BZ701, but also can be used to trip test 30mA RCDs by using the touchpad.

Martindale Electric’s socket testers make it easy for electricians to choose the right level of features they need for their work and offer a crucial first line of defence when it comes to electrical safety.

These three sophisticated testers are in addition to the Martindale famous Check Plug and “Buzz-it” ranges.
