This Model 10310-9 Frostpoint/Dewpoint Indicator detects and indicates the frostpoint or dewpoint of gas sampled from a low pressure air system, from 80 to 150 psig.
The Indicator, called the Frostpointer(TM), is housed in a rugged, portable unit carried to the test site and connected, to the gas source by a sampling hose (supplied with the Frostpointer(TM)). To establish the frostpoint and dewpoint, the sample gas is cooled by an internal vortex cooling system. The resulting frost or dew is viewed through a unique, patented optical and oblique lighting system. The corresponding frostpoint or dewpoint is then read from the digital meter on the front panel. The Frostpointer(TM) provides complete control of both volume and cool-down rate of sample gas over the chilled mirror surface.
The Frostpointer(TM) can also measure temperatures from one to three remote sources connected to terminal sets on the the front panel. Merely use the Selector Switch to choose a terminal set, and read the remote temperature on the digital meter.
