A refrigerant pressure-temperature (PT) chart designed for the iPhone and iPod Touch has been released by Bitzer, Oakwood, Ga.

The application is an intuitive, saturated-pressure-temperature reference chart that focuses on the most common refrigerants found in refrigeration and air-conditioning systems. The “app” provides users with a customizable listing of refrigerants, allowing them to select and arrange the refrigerants in any order. The “PT” iPhone application is the only reference tool that offers both imperial and metric units, according to the company.

To download it, visit the Apple App Store and search for “Bitzer.” Refrigerants currently available include R124, R134a, R22, R23, R32, R404A, R407A, R407C, R410A, R507A and R290.
