Steam Tables Pro vs LuxMeter Easy

Calculate water and steam properties with the IAPWS-IF97 equations. Choose six input combinations: pressure and temperature (p·T), pressure and enthalpy (p·h), pressure and entropy (p·s), pressure and quality (p·x), temperature and quality (T·x), or enthalpy and entropy (h·s). Find absolute pressure, temperature, enthalpy, entropy, vapor quality, specific volume, internal energy, density, and thermodynamic region. Explore heat capacities, speed of sound, the Cp/Cv ratio, vapor volume fraction, and transport properties. Save states to compare results and plot points on T–s, p–h, and h–s diagrams. Choose the units you use in study or work. Pressure units explicitly indicate absolute pressure, such as bar(a). Learn inside the app with a usage guide, essential concepts, explanations of each property, and worked examples for boilers, turbines, and valves. Explore boiler superheating, turbine isentropic efficiency, and constant enthalpy during throttling, with T–s and p–h diagrams. The calculator, guide, and tutorial are available offline in English and Portuguese.

LuxMeter Easy is easy, accurate and versatile, it allows you to measure the lighting of an environment, evaluating the average value of the lighting with great precision. LuxMeter Easy, uses the reflected light to calculate the relative intensity of the sources. it allows to measure directly the intensity of light emitted by a source. In addition to measuring Lux or Candles on square meters, LuxMeter Easy allows you to evaluate the diffusion of light using the IR, UV or GrayScale color scale to identify objects or areas that reflect higher or lower light, highlighted by different colors. With LuxMeter Easy you can improve your lighting configurations only by using your smartphone in a very simple way. Attention!! it is not an app for photography, but only for those who need to configure the environmental lights.
