The HT Italia XL422 is a three-phase TRMS current data logger manufactured by HT Italia srl of Faenza, Italy. It is a self-contained, battery-powered instrument that measures and records true-RMS current, designed to be installed around a conductor up to 174 mm in diameter for unattended current recording over extended periods.

A current data logger records electrical current readings at programmed intervals and stores them in onboard memory for later download and analysis. Unlike a handheld meter that displays an instantaneous value, a logger captures how current behaves over hours, days, or weeks, allowing trends and variations to be reviewed after the measurement window has closed.

ValueTronics stocks and holds its own test-and-measurement inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois.
