Quick refrigerant identification; the chosen tool for stopping bad refrigerant from entering the country
Unfortunately, still a lot of illegal or contraband refrigerants are sold worldwide. The phase-out of R22 has prompted shady businessmen to knowingly mislabel refrigerants and send them worldwide.
Fortunately, many port authorities use refrigerant identification tools made by Neutronics. Any of the tools will quickly determine whether the product that is listed on the label or documents is actually in the cylinders.
This is how contraband and poorly performing refrigerants are kept out.
