The water vapor tape recorder, observed by frost point hygrometer sondes, proved useful as an independent measure of the elapsed time since the air entered the stratosphere.
(4) Baseline water content in the dried sweep gas varied among gas cylinders; concentrations ranged between 200 parts-per-billion by volume (nL/L) and 500 nL/L, which corresponded to a vapor pressure range of [approximately equal to]17 mPa to [approximately equal to]44 mPa, or a frost point range from about -90 [degrees]C to -80 [degrees]C at the average system pressure of 87.02 kPa [+ or -] 0.24 kPa.
We are also dedicated to providing the most reliable, innovative, and versatile solutions for varying applications and for measurement of Pressure, temperature, PPM and Oxygen sensors in addition to Dew and frost point.
With multistage electrical cooling it's possible to measure the dew point and also the frost point, giving relative humidity down to frost points of -70[degrees]C, but lower temperatures will reduce accuracy to 10 percent RH at the extreme low end.
As the Martian night wears on, the surface of the planet cools below the frost point, and water vapor in the atmosphere gets deposited on the ground.
