THERM-O-WATCH (TOW) was originally developed in 1957 as a "thermometer watcher" to monitor temperatures that required tedious watching.  But TOW is actually a liquid level monitor that responds to the level of polar liquids in tubing, sight glasses and other containers.  Many thousands of TOW have been used over the years in conjunction with Hg thermometers; however, the true applicability of this unique lab instrument is in monitoring liquid levels and pressure/vacuum in the lab.
