Although the Davis Halide Meter is one of the best portable instruments so far encountered for the evaluation of health hazards which may result from the inhalation of organic chloride vapors, it has not been completely free of difficulties. These problems are described along with corrective measures which have been developed. A partial list of items considered includes: effect of water vapor, inability to zero the instrument, effect of slit width, effects of high concentrations of organic halide vapors upon subsequent use and required calibration.
