The PLI Digital unit, launched in June 2013 is a powerful new additional to the PLI liquid level indicator range. With all the features of the original PLI , the PLI Digital has the ability to take a reading from cylinders in poor condition, or suffering from a layer of rust. It also has an in-built thermometer (in both C & F), an easy-to-read digital display, one-button-set-up function for faster cylinder testing and smart plug, which enables the signal strength to be monitored by an audio signal from an internal speaker.
