Watch the video demonstration of the Portalevel® MAX PLUS + Portasteele® CALCULATOR measuring the liquid level of a 45 KG / 100 lbs CO2 cylinder at 13.8°C.

It is commonly known that CO2 levels can vary with temperature. However, the Portasteele® CALCULATOR compensates for the effects of temperature, providing you with accurate agent quantity readings at all times.

When used in conjunction with the Portasteele® CALCULATOR, the Portalevel® MAX PLUS provides traceability of liquid level height results directly to the agent weight, which is the only documented evidence of cylinder contents provided by the manufacturer or filling station.

The Portalevel® MAX PLUS, used together with the Portasteele® CALCULATOR, allows you to measure cylinder contents with precision up to 1%, with both liquid level height and agent weight results readily available.

This ensures compliance with ISO and NFPA regulations for periodic CO2 cylinder contents inspection.
