A PT chart is a tool used in refrigeration and air conditioning systems to determine refrigerant pressure and temperature relationships. It helps technicians to diagnose and troubleshoot refrigeration issues. In recent years, with the rise of technology, PT chart apps have been developed to make the process even easier. These apps can be particularly helpful for HVAC professionals who need to quickly access PT charts on-the-go. In this article, we will review the best PT chart app for Android devices to help you make an informed decision when selecting an app for your needs.
We have compiled a list of 7 Best Pt Chart App Android for your consideration, which have undergone rigorous testing and evaluation by our team of experts.

7 Best Pt Chart App Android
1. Chemours PT Calc
Chemours has developed the Pressure-Temperature (PT) calculator mobile app, a modern adaptation of the traditional paper P/T chart. The app is designed to provide HVACR service technicians with quick and accurate refrigerant data on the go, enabling reliable system diagnostics and response. The app includes all major refrigerant products, including Opteon™ HFO refrigerants, as well as their Freon™ HFC and HCFC incumbents. Each refrigerant option provides data on % composition, physical, chemical, environmental properties, temperature glide, typical use applications, and lubricant recommendations. The app also displays the corresponding pressure when a temperature input is given or provides the temperature for a given pressure reading.
For refrigerant blends, both saturated vapor and saturated liquid values are provided by the Chemours PT Calc. The user can specify the data in either English or metric units. Furthermore, the app calculates the superheat and/or subcooling from an operating system based on input from the service contractor in the field. This allows for quick and accurate charging, start up, and/or troubleshooting HVAC systems. The Chemours PT Calc is offered as a free app to users.
2. PT Chart
Honeywell has introduced a new option for HVAC mechanics who currently use the standard paper pressure-temperature (PT) chart. The company offers a colorful display that enables users to select a refrigerant and obtain the necessary data for field tasks. The touch screen feature allows users to swiftly calculate superheat and subcool averages for precise control.
3. P-T Calculator
National Refrigerants has developed a Pressure/Temperature calculation tool that is designed to assist HVAC/R technicians in their work. This app is more than just a PT chart, as it can calculate both simple pressure/temperature relationships and superheat/subcool temperatures. The tool also has the capability to display both saturated vapor and saturated liquid values for refrigerant blends. Additionally, a graphic display is available for blends, which shows the entering, mid-point, and outlet temperature, as well as line temperature within the superheat/subcool screen.
Users can input pressure or temperature(s) on any screen, and the other values will be automatically calculated and displayed. The app also features automatic altitude correction (if location services are enabled), English/Metric units, and a refrigerant favorites list that is easily accessible. Additionally, there is supplementary information about refrigerants and links to NRI’s website, as well as links to the NRI Lubricant Cross Reference app and NRI Branch Locator tool.
4. Forane® Refrigerants Tool Belt
The Forane® Refrigerant Tool Belt is a useful tool for HVACR professionals working in refrigeration and AC. The app offers cross-unit PT charts for each refrigerant, allowing users to input pressure or temperature readings and receive corresponding values. Additionally, the app provides calculations for subcooling and superheat values, as well as information on the properties of available Forane® brand and generic refrigerants.
Users can also scan Forane® refrigerant product codes to ensure authenticity and avoid counterfeit cylinders, access educational refrigerant videos, and translate the app content into eight languages. The app also offers the option to visit the Forane® website for further information or contact the Forane® team with any questions.
All in all, the Forane® Refrigerant Tool Belt is a handy app for HVACR professionals looking to review PT charts on-the-go, calculate values, and access important information on refrigerant properties. Learn more at https://www.forane.com.
5. Emerson PT Pro
Emerson Climate Technologies offers the PT Pro™ application for convenient access to pressure and temperature conversions. The application allows users to select a refrigerant and input a temperature measurement in either Celsius or Fahrenheit to obtain the corresponding saturated pressure measurement in Bar or Psig. Alternatively, users may input a pressure measurement to obtain the corresponding saturated temperature. The PT Pro™ application is available for free download on Android devices.
6. Ref Tools
Ref Tools is a free app that offers essential tools for HVACR technicians. The latest update includes the addition of the TXV Superheat Tuner app that helps fine-tune superheat in under 15 minutes. The app also provides access to eight popular and useful air conditioning and refrigeration tools such as the Refrigerant Slider, the Low-GWP Tool, the Troubleshooter, and more. The app also allows users to track their most visited service sites and save unique settings for each one.
The Refrigerant Slider, now a part of Ref Tools, helps users calculate the pressure-to-temperature ratio for over 80 refrigerants, including natural refrigerants like ammonia and transcritical CO2. It also provides information about each refrigerant, including its Global Warming Potential and Ozone Depleting Potential. The P/T calculations for the refrigerants use extended curve-fitting models based on Refprop 10 results.
App support is available through the in-app feedback function or by emailing coolapp@danfoss.com. Danfoss is a global company that engineers advanced technologies for refrigeration, air conditioning, heating, motor control, and mobile machinery. They employ 28,000 people and serve customers in over 100 countries. Terms and Conditions apply for the use of the app.
7. HVACR Check & Charge
The HVACR Check & Charge™ mobile app by Emerson Climate Technologies is a refrigerant charge calculator for air conditioning and refrigeration systems. It allows contractors to calculate the correct system refrigerant charge for various refrigerants including R-22, R-410A, R-32, R-407C, and others. The app provides Superheat, Subcooling, and Airflow calculators, as well as PT (Pressure/Temperature) charts and a Superheat target finder.
The app is designed to assist contractors in determining the proper system refrigerant charge based on specified system temperatures and environmental loads. The app supports both Imperial and Metric units of measurement.
This app is one of several mobile applications offered by Emerson Climate Technologies, and more information can be found at their website.
