Hands-Off: 3M’s Auto Calibrator Takes the Guesswork Out of Refillable Low-Pressure Systems

For spray foam applications, properly maintaining the A and B material in a 1:1 proportion, also known as being “on-ratio,” is one of the most significant factors affecting application quality. Low-pressure spray foam kits, including refillable units, have long endured the tedious, wasteful and time-consuming process of manual calibration to maintain on-ratio material. The Auto Calibrator, the new proportioner component for the 3M™ Refillable Spray Foam Insulation System, was designed to mitigate those shortcomings.

The Issues at Hand 

The first challenge for manual calibration is the learning curve for identifying off-ratio material flow and then adjusting it to be on-ratio.
