Guys, I'm looking for a dew point meter to measure the dew point of natural gas which used as instrument gas in offhore oil & gas platforms. The dewpoint to measure is 12 to 14C max below ambient temp of 22C as per the instrument gas skid design data sheet. Without the specified dew point achieved, the reliability of all consumer instruments downstream will be affected. Appreciate any syggestions for a few good one. I have searched internet but too many of them being advertised.
