Laser levels are a mainstream tool typically used in the construction and surveying industry for leveling and aligning applications. They project a constant red or green line onto a surface on a horizontal or vertical plane and can be used for anything from hanging a picture to professional building work.

The measurement of fluid density, viscosity, temperature, and pressure in the field of use will also affect the measurement accuracy of the flow meter, especially in the case of gas flow measurement, it is obvious that the viscosity change of high-viscosity liquid due to temperature changes affects the measurement accuracy. Factors such as the high center of gravity and eccentricity of the float will cause left and right swings during work, and the rapid rotation of the float off-axis in place will affect the measurement accuracy. (At this time, the flow rate is often too large, that is, the float shakes to make the flow area smaller).

Before using the spectrophotometer, the user should first understand the structure and working principle of the spectrophotometer, as well as the functions of each control knob. Before turning on the power, you should check the safety performance of the instrument. The power wiring should be firm, and the power should be good. The initial position of each adjustment knob should be correct and then press the power switch.
