Bruce:

I am going to be calibrating some of the Campbell Scientific 229 sensors.
 I am going to use pressure from 0-400 kPa but I would like to calibrate
at a higher kPa.  I read somewhere that letting the sensors "hang" in a
jar containing a solution of potassium sulfate at 20 degrees Celcius will
give an equivalent total suction of 4120 kPa.  Do you know of a solution
(and temperature) that might give an equivalent total suction between 400
and 4120 kPa?  I would really appreciate the input.
