Not only is voltage very critical but the amp can tell us how hard a compressor is working and is a good indication of a charge
Evaporator superheat is a calculation of the amount of liquid refrigerant going into the evaporator and the heat load of an air conditioner evaporator.
Subcooling is the amount of liquid held back in the condenser. This allows the liquid to give up more heat, below saturated pressure- temperature.
Temperature difference of an evaporator coil will vary with the total heat of the air entering the evaporator and the load on the condenser. This temperature will vary from 10º F to 30º F depending on total heat of the air entering the evaporator.

Pressure / temperature relationships are provided for the following refrigerants:
HVAC Refrigerant PT™ can display pressure in the following units:
* psig - pounds per square inch gauge (pressure is relative to atmospheric pressure)
* kPa - kilopascal
* psia - pounds per square inch absolute (pressure is relative to a vacuum)
* inHg - Inches of Mercury
* atm - standard atmosphere
* bara - bar absolute (pressure is relative to a vacuum)
* barg - bar gauge (pressure is relative to atmospheric pressure)
HVAC Refrigerant PT™ provides a detailed list of physical properties for the refrigerant selected including classification, density, critical temperatures and pressures, specific heat, ozone depletion potential, safety rating, applications, and recommended lubricant for the refrigerant. It also provides pressure/temperature charts for many common refrigerants used in the industry.
If you are not 100% satisfied with this app please email us at email@example.com so we can make things right before posting any negative reviews. We are also open to any suggestions you may have for future enhancements to this product.

Getting reports of the app alerting that the web page is not accessible. I've tried to repeat this behavior and cannot. I installed from the Play Store on a Samsung S4 and Tab 2 and the app works as it should without errors on my end.
Added internet permission to try and resolve loading issue. The app works fine on the above listed devices and emulators. Sorry that I don't have more testing devices available.
The HVAC Check & Charge™ mobile app from Emerson Climate Technologies provides an on-site refrigerant charge calculator for air conditioning applications. Based on historic sliding cardboard charge calculators, this app allows contractors to easily calculate correct system refrigerant charge for R-22 or R-410A. Contractors can simply choose Subcooling, Superheat, or Airflow and enter the specified system temperatures along with the latent and sensible environmental loads. These values are then used to determine the proper system charge and whether the charge amount needs to be altered based on these conditions.
-Superheat Calculator (non TXV)
-Subcooling Calculator (TXV)
-For use with R-22 or R-410A
Information on this and other Emerson Climate mobile applications is available at ww.EmersonClimate.com/mobileapp.
Assists with calculating proper system refrigerant charge based on operating conditions.

Based on the well-known Danfoss Refrigerant Slider, KoolApp™ turns your Android smartphone into a user-friendly, quick pressure-to-temperature refrigerant converter. It is designed for installers, distributors and producers of air conditioning and refrigeration equipment, and will also be useful for other industry professionals and students.
In the current version there are 48 different refrigerants including both “natural” and “traditional” refrigerants, covering almost all media normally used in air conditioning and refrigeration systems. More will be added via updates pending user requests.
KoolApp is based on the NIST Refrigerant Properties and is using the Antoine equations for the conversion and you will be able to see both dew- and bubble- points for refrigerants with glide.
Included are also a few additional informations regarding the respective refrigerants.
On the respective refrigerants, you can see additional information like Global Warming Potential (GWP) and Ozone Depleting Potential (ODP).
KoolApp™ gives you the freedom of calculating in either °C and bar, or °F and psi.
KoolAppTM belongs to Danfoss A/S
HOW TO USE
In the left side of the screen, an intuitive slider helps you to quickly find the pressure or temperature reference, while the precise pressure and temperature reads on the right side fields.
By simply tapping these fields, you can also type in your actual pressure or temperature reading, and KoolApp™ will instantly give you the corresponding figure – and move the slider for visual indication.
Changing from SI units to US Customary units is a one-button operation, and you can do this directly within the conversion tool.
KoolApp™ gives you more than 48 refrigerants, but also allows you to select your favourites among them, making them easily accessible on the top of the selection list.
