We have a variety of gauges that enable you to measure vacuum with Hastings tubes for cryogenic applications.
We have Hastings based portable gauges to check vacuum jacketed pipes.
In the cryogenic industry, we find that Hastings vacuum gauge thermocouple tubes are often found permanently mounted in cryogenic vessels. Often, it might make sense to have a battery operated vacuum gauge that enables you to walk along a cryogenic vessel, and measure the vacuum at that point. The range of interest is in the 10mTorr range. We have a variety of gauges that enable you to measure vacuum with Hastings tubes, and our most popular products for this application is the battery operated Model 100H for battery power, and the Model 215H for the panel mount AC version.
