3M QuesTemp Series WBGT Thermal Index Monitor

QuesTempThe series of regional heat index monitoring instruments is from the United States3M QUESTA device launched by the company that responds quickly and accurately evaluates the thermal stress in areas with potential thermal stress hazards to the environment,QuesTempThe thermal index monitor is equipped with the most advanced technologyWBGTSensor Technology andWBGTThe calculation of index values comprehensively considers environmental temperature, humidity, wind speed (due to the cooling effect of water evaporation on the body), as well as radiation heat from equipment such as the sun, furnaces, ovens, and boilers, which can facilitate operators to quickly and accurately obtain the total body heat index of the measurement environment.

QuesTempThe series of regional heat index monitoring instruments fully comply with China's requirements“GB Z T189.7-2007High temperature workplace "standard, measurable indoors/outdoorWBGTValue, dry ball/Wet Bulb/Black sphere temperature value, relative humidity, heat index, and humidity index. Additionally, there are options available2Inches and6Inch black ball sensor, or optional200The foot extension cable separates the sensor module from the host, making it particularly suitable for use in high-temperature workplaces. Additionally, it is possible to expand the connection of three sets of sensors and measure the head, chest, abdomen, and feet simultaneously3At different heightsWBGTValue, and after weighted calculation, it conforms toISOStandard.

QuesTempThe series of regional heat index monitoring instruments includes two types6Model number:

1)Using standard water and humidity sensors3The series includes3Model number:QT-32、QT-34、QT-36Among themQT-32As a basic type, possessing completeWBGTIndex monitoring function,QT-34For record keeping purposes, possessingQT-32All functions of the device are integrated with memory, which can save measurement indices on site and pass throughQSP-IIThe software downloads the measurement data toPCFurther analysis is conducted,QT-36As a high-end functional model, it not only hasQT-34All functions of, and expandable wind speed sensor to measure wind speed and calculate expected cold and heat index（PMV）And the average predicted dissatisfaction score（PPD）.

2)Using an anhydrous humidity sensor4The series includes3Model number:QT-44、QT-46、QT-48NThis series is suitable for work environments where daily maintenance of instruments is not possible. Use high-quality humidity sensors and specialized algorithms to calculate indoor humidity/outdoorWBGTValue, relative humidity, and heat index/Humidex.QT-44Basic model of anhydrous humidity sensor,Capable of data recording and output functions（QSP-IISoftware),QT-46For advanced models, equipped withQT-44Function, and optional wind speed sensor to measure wind speed and calculate expected cold and hot sensation index（PMV）And the average predicted dissatisfaction score（PPD），QT-48NFor special customized models, equipped withQT-44All functions of, and optionaldType attachments and heavy-duty lanyards are suitable for rapid assessment in event recording mode.
