The latest update for Blender Toolkit now includes a feature that allows you to copy the results of your calculations to the clipboard for easy pasting or sharing.
New feature: Quick selection of standard volumes. The set of volumes can be individually adjusted in "Common settings".

New feature: Consideration of bottle-warming during filling
How much bar does the pressure gauge show at a e.g. filled with air scuba tank at 16 C degrees warm water, if this bottle was previously filled at 26 C degrees air temperature up to 200 bar? The correct answer is: only about 190 bar. With a temperature change of only 10 degrees results in a pressure difference of about 4.9%. This fact clearly shows how important it is to measure the temperature change at every filling step and to adjust the target pressure accordingly.
The new feature see Fig. 1 was introduced to solve this problem

Clicking on the icon opens a dialog in which the calculated gas volume is used as a reference and the correct temperature is determined for the actual temperature. The bottle temperature may e.g. be measured with the help of an infrared thermometer. This value is set in the dialog box (Fig. 2). The calculated pressure value shows when the filling step is completed at this temperature.

It is important to note that the ambient temperature for the calculation of the entire filling process is set only once and thereafter remains unchanged. (Fig. 3)

New feature: Added CCR rebreather diluent END calculator for different depths with a chosen PPO2 setpoint
DIR-Wetnotes now has a successor "Gas blender toolkit"
The "Gas Blender Toolkit" for all devices and platforms. Have fun with it.
