Combination Flux Hydrometer-Thermometer

These quality control instruments are designed to quickly test, accurately monitor, and help maintain the efficiency of fluxes in wave and drag soldering operations. They are completely self-contained with a squeeze bulb to eliminate the need for beakers or graduates. Graduations from 0.800" to 1.000" cover a full range of soldering fluxes. In addition to measuring the normal specific gravity range, Model 24-040 has a built-in thermometer for easily checking temperature calibration.
