The factory setting for gas model has been changed to: "real gas (vdW)". Build "2020030801" Thank you for feedback.

Hi all, it's been a while since this chat was opened. Meanwhile an android and iOS App of the successor tool is available at the official platforms. The desktop version is available here: Gas blender toolkit

interesting and noteworthy is the weight difference of the filled gases depending on the mixture. For example, a stage filled to 200 bar with oxygen weighs almost 1.5 kg more than a stage with TX18 / 45. In general, a comparison of the gas weights is already fascinating: 80 cuft stage (200 bar...

as a matter of fact this caclulation seems to be useful and illustrative. ... on going ...

At first glance, this functionality belongs more to the area of CCR software. I will think about it. Thank you.

a) the start (computing) temperature should be set in "Settings", the data in Result table are reference data b) during fill step i measure the current temperature and can see in c) up to which pressure i should fill the tank to get computed "amount" of gas. after all i can start the next step...

i don't measure the temperatures :daydream:, but the most simple variant could be a non contact thermometer, for example like this one...

A new feature added: during filling the cylinder gets warmed up. It is essential, to know the exactly pressure for deviated temperature. The "Gas blender toolkit" helps to see these deviations with help of so named Isochore of scuba tank.

g/L for density even in "imperial" units :)

The question I ask myself is how high is the relevance of the gas density when planning the dive. Whatever must be considered is the toxic and narcotic effect of the respiratory gases in depth. Is there a constellation where we stay within these limits and the gas density exceeds 6 g / l? If...

Good idea, thank you! added new mode: (O2, Topoff, He)

ok, please set in settings "show details -> verbose" to display this new column

change: a new option "display sliders" has been added in common settings :). Thank you for your feedback!

to input a value please click on the value you about to change. With a click on the value the input field will shown. The sliders are optional.

We are pleased to announce the availability of new Application "Gas blender toolkit". https://blender-toolkit.t-provider.de "Gas blender toolkit" is a useful and comprehensive toolkit for scuba gas blender and PSCR divers - partial pressure/ continuous blending of trimix, nitrox, heliox -...

True, one of the biggest sources of error is warming. The calculations with different gas models (Real and Ideal Gas) show how far the deviations are apart. As a tip, with this program, the different calculations can be easily compared: Gas blender toolkit
