Habotest HT5910 Digital RCD/Loop Earth Tester
The Habotest HT5910 resistance tester is a tool that will allow you to take resistance measurements of power circuits. It offers loop, RCD and AUTORAMP measurements. It has an easy-to-read LCD display that will provide you with quick and clear information about the data being taken.

Functionality first and foremost
With the help of the meter you will successfully obtain information about the earth resistance. You will gain access to 100 groups, which store data from the measurements taken. The device is equipped with a special button that allows you to select the desired measurement type and start the meter operation with the "Measurement" button.

Ease of use
The HT5910 uses an easy-to-read LCD screen that displays all the data being received. This gives you instant access to your measurements, even in dim or bright environments. The meter draws its power from 6 AA batteries, which must be purchased separately.
