A review of on- and off-line moisture and humidity sensors covers instruments based on the capacitive principle such as Panametrics' Aquamax II and those developed by Ondyne, Moisture Control Systems, Phys-Chemical Research Corp., Shaw Instruments, and Diversified Engineering; instruments based on the microwave plus gamma and nuclear plus gamma radiation principles such as those by Kay-Ray and Ohmart Corp., respectively; sensors based on the saturated salt principle such as Foxboro's self-heated lithium chloride sensor; Kahn and Co.'s electrolytic hygrometer for monitoring the moisture content of pure gases or gas mixtures in natural gas transmissions; the Ohaus gravimetric instrument; microprocessor-based titrators by Foxboro Analytical and Photovolt Corp.; instruments which sense moving web moisture such as Beckman Instrument's Hygroline System HMP20 and Hy-Cal Engineering's sensor; IR stack gas analyzers by Anarad Inc. and Moisture Systems Corp.; optical hygrometers by EG and G and General Eastern; Panametrics' Model 4000 moisture computer; and Du Pont's standard 560 analyzer and new controller.
