In the high-low temperature alternating humidity test and the cyclic damp heat test, the most commonly used method for measuring humidity is the dry-wet bulb method. This technique, developed in the 18th century, has a long history and remains widely applied today. The dry-wet bulb method is an indirect approach that calculates humidity based on the difference between the readings of two thermometers: one with a dry bulb and one with a wet bulb. However, this method relies on specific conditions, such as a wind speed of at least 2.5 m/s near the wet bulb to ensure accurate results.
Most standard dry-wet bulb thermometers simplify these requirements, which limits their accuracy to approximately 5–7% RH. It's important to understand that the dry and wet bulbs are not static instruments. Simply increasing the precision of the thermometers does not necessarily lead to more accurate humidity measurements. Factors like air flow, temperature stability, and environmental conditions all play a crucial role in the reliability of the readings.

3 Stage Standing Desk
As the name suggests, the Sit Stand Desk is a table that can be raised and lowered, so the lifting function is the biggest feature of this Height Adjustable Table. The lifting column is up and down through the control of the control box. Therefore, the most important part of an Electric Adjustable Desk is the lifting column (including the motor), the control box, and the hand controller. Without one of these three parts, the lifting function cannot be realized. The two lifting columns of the Dual Motor Standing Desk are controlled by two motors, and the stability and fluency of the dual-motors are more prominent among similar products.
