在测定高温车间气象条件时,为了保证数的准确性,必须正确使用测定仪器,否则,测定数据常常偏高或偏低。下面介绍几种最常用的仪器在使用中应注意的事项。 一、液体温度计 必须避免辐射热的影响,测定时应在温度计和热源之间加一挡板,或者用铝箔等反射辐射热的材料将温度计球部围罩起来。要测定5分钟以后才能读数,并防止水滴落在温度计球部。 二、通风温湿度计 测定时,应先用装有清洁水的橡皮球的吸管,湿润湿球,再用钥匙旋紧风扇的发条,测
In the determination of high temperature workshop weather conditions, in order to ensure the accuracy of the number, you must correctly use the measuring instrument, otherwise, the measured data is often high or low. Here are some of the most commonly used instruments in use should pay attention to the matter. First, the liquid thermometer must be to avoid the impact of radiant heat, the measurement should be between the thermometer and the heat source plus a baffle, or aluminum foil and other materials that reflect radiant heat to cover the thermometer ball. To be measured after 5 minutes to read, and to prevent water droplets fall on the thermometer ball. Second, the ventilation hygrometer determination, should first be fitted with clean water rubber ball straw, wet wet ball, and then use the key to tighten the fan winding, measuring
