How To Choose The Best Non-Contact Voltage Tester?
Size & Ergonomic Design
When it comes to the size of a non-contact voltage tester, choose a model that’s small and lightweight enough for easy transport.
The design also comes into consideration.
For ease of use, we highly recommend picking a voltage tester with an ergonomic build. When using a well-designed gadget for a long period of time, there will be no hand tiredness.
Bonus: Non-contact voltage testers with hooks are also a great option as you could even keep one in your shirt pocket.
Sensitivity
Choose a non-contact voltage tester that allows you to adjust its sensitivity level so that you can fine-tune the range to suit your needs.
This function protects your test results from being tainted by unintended electric signals while ensuring that the voltages you want to detect are picked up by the tool.
Safety
As a general rule, the non-contact voltage detector you'll purchase should fall into one of the approved measuring categories of safety organizations—specifically, from CAT I to CAT IV.
And, after the CAT classification, please consider the AC voltage. The voltage rating of the tester is indicated by the specified number.
A personal email to classification bodies may help you assess whether a product's certification is legitimate.
Voltage Range Detection
There are a number of non-contact voltage testers that can detect either high voltage alternating current from 12-48V (such as switches, lighting fixtures, and outlets) or low voltage AC from 12-48V (such as thermostats, security equipment, and doorbells), or both.
We suggest going for dual-range voltage detection because it can be used for several purposes, which eliminates the need for multiple devices and saves money.
Voltage notification
A non-contact voltage tester that can’t clearly indicate that it has found a voltage is useless, no matter what. So, it is important to consider the notification methods that the unit has.
There are two common options: via audible sound and via LED light (that’s frequently located in the device’s tip)
In general, the more notification options, the less chance of misinterpreting voltage test findings.
