With all of the features of the original PLI, the American Bureau of Shipping (ABS) type approved PLI Digital™ can take a reading from cylinders in poor condition, or suffering from a layer of rust.

It also has an in-built thermometer (showing readings in both Celsius [°C] and Fahrenheit [°F]), and an easy to read digital display. It features a one-button set-up function for faster cylinder detection, and a smart plug, which enables the signal strength to be monitored by an audio signal from an internal speaker.
