PLI PLUS™

Non-Invasive Testing of CO₂ and Cryogenic Cylinders

Get fast, accurate, non-invasive liquid level readings for pressurised gas cylinders with the PLI PLUS™ Portable Liquid Level Gauge – an essential tool for shipboard safety checks, fire system maintenance, and marine service inspections. With no need to disconnect or disturb the cylinder, the PLI PLUS™ uses advanced ultrasonic technology to pinpoint liquid-gas interfaces through the cylinder wall.

Compact, easy to use, and highly reliable, it’s ideal for marine engineers, safety officers, and offshore service teams working with CO₂, halon, and other liquefied gases.
