How do I perform pressure measurement in vapours? (1 answer)
by Michael Leon, over 3 years ago
For pressure measurement in vapours, it is recommended to use a siphon that will bring down the temperature to ambient level. Also, mounting the device with the shutoff device and siphon below the tapping point can bring only minor heat effects to the device and negligible errors during measurement.
