Relative humidity shows how much moisture the air could hold compared to how much it does hold. This percentage differs at various temperatures as warmer air has a greater capacity for holding moisture than cooler air. Determining the relative humidity using two thermometers lets you cheaply find out if your home or area has too much or too little moisture in it. Excess moisture can breed mold while not enough dries out skin.

Dry bulb temperature is typically called “air temperature.” The temperature is read off a normal thermometer, and the water content of the air does not affect its reading.

The bimetallic thermometer should be checked and calibrated every half a year under the condition of the prescribed process, so as to ensure normal use. Of course, according to the actual situation, it can be adjusted to one or two years.

In a laboratory setting, accuracy is an indication of how close your measurements are to the actual, true measure of something, whereas precision is an indication of how close your measurements are to one another.

Based on a thermoscope invented by Galileo Galilei in the early 1600s, the thermometer on your co-worker's desk is called a Galileo thermometer.

Shanghai QualityWell was founded in Jiading, Shanghai on Aug.8th,2008. There was a team of only four persons founding this company. Nowadays, we have experienced ten years’ time together.

From 2008 to 2018, we have been running for 10 years.
