    The use of hot-wire technology to measure the size distribution of droplets contained in liquid sprays has recently been expanded to include certain specific insecticide materials in addition to previously investigated liquids such as water and mineral oil. Classes of liquids associated with different calibrations can be identified by a relatively straightforward measurement of the surface tension. Thus, it is not necessary to perform a detailed optical calibration of every material. Also discussed are the size ranges of various liquids, details of the droplet/wire interaction, aerodynamic effects, effects of the longitudinal temperature distribution, and eccentricity. Uses of hot-wire technology and its advantages over optical techniques and the older slide-wave techniques will be discussed, along with current commercially available instruments and new instruments being developed.
