SIBATA SCIENTIFIC TECHNOLOGY Black Ball Thermometer GTM-1 For IES-4000

A black bulb thermometer measures the radiant heat of an object. GTM-1 is a black bulb thermometer with a diameter of 75mm manufactured by the manufacturer. This is a measurement factor for the comfort equation of the thermal environment evaluation index PMV (Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied), which are based on the heat load on the human body and the human thermal sensation index. Masu. By measuring radiant heat using a bulb thermometer, it can be combined with the six main items that can be measured with the IES-5000 (suspended dust, airflow, carbon monoxide (CO), carbon dioxide (CO2), temperature, and relative humidity). , PMV value, and PPD value can be automatically calculated. This allows us to find the international standard ``ISO 7730: Indicators of a moderate thermal environment.''
