Abstract

The invention provides a portable WBGT (web-bulb globe temperature) index instrument, comprising: a housing; a dry bulb temperature sensor, a natural wet bulb temperature sensor, and a black bulb temperature sensor which are arranged at the top of the housing; an instrument switch arranged on the lateral side of the housing; a timing switch arranged on the surface of the housing; a selector switcharranged on the lateral side of the housing; a processor and a data storage which are arranged in the housing. The natural wet bulb temperature sensor and the black bulb temperature sensor are connected in series and are connected parallelly with the dry bulb temperature sensor; the sensors are connected with the processor through the selector switch; the timing switch is connected with the processor and is used for starting the processor to calculate WBGT indexes of a current environment according to preset balance time; the data storage is connected with the processor and is used for storing calculation results of the processor. The portable WBGT index instrument can be used to accurately master the actual levels of high temperatures which operators contact in difference places, workingefficiency is improved, and accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of on-site occupational health detection, and in particular relates to a portable WBGT index meter for recording the high-temperature exposure level of workers. Background technique [0002] High-temperature operations widely exist in industries such as electric power, construction, metallurgy, and petrochemicals. In the hottest months of the year, such as July and August, workers are prone to high-temperature heatstroke, which endangers the health of workers. [0003] The main indicator for evaluating the exposure level of high temperature operations is the WBGT index. According to the current standard "Measurement of Physical Factors in the Workplace Part 7: High Temperature" (GBZ / T 189.7-2007): high temperature detection instruments are dry bulb thermometers and natural wet bulb thermometers And the black bulb thermometer, and the natural wet bulb thermometer needs to be filled with distilled water before...
