Volume Meter

Volume Meter

I. Overview

Volume MeterIt is an instrument used for screening and identifying antipyretic agents. It is an instrument that evaluates the efficacy of antipyretic agents by measuring the process of reducing swelling in rat toes after inflammation, and understands the duration and efficacy of antipyretic agents. The instrument has accurate measurement, accurate timing, accurate printing, and convenient operation, as well as the progressiveness of modern high-tech technology. Compared with similar foreign products, the instrument has improved a grade in both style, structure and accuracy, but the requirements for the use of media (liquid) and the requirements for operating technology are far lower than those of similar foreign products. It can be said that the instrument is an advanced and practical instrument for measuring rat toe swelling at present in China.

XR-YLS-7B is an improvement on the YLS-7A model, which adds backlight, handrest, water surface probe linkage device, and detachable measuring cup while maintaining the original measurement accuracy. It has greatly improved performance and simplified operation, making the original operation simpler, more convenient, more accurate, and superior, reaching a new and higher level.

3、 Precautions

1. The instrument should be kept clean, and when not in use for a long time, the water should be poured out and placed in a ventilated and dry place.

2. After use, the instrument should be wiped clean in a timely manner. When wiping, a damp cloth dipped in cleaning agent can be used, and organic solvents must not be used, otherwise it will damage the appearance of the instrument surface.

Although the base of the measuring cylinder of the instrument has been treated with passivation technology, it should also avoid contact with strong acids and alkalis. If there is any dirt, please wipe it with a soft cloth dipped in cleaning agent and rinse it with clean water. When removing and wiping the measuring cylinder, be extra careful to avoid breaking it.

4. This instrument is a precision instrument and should be placed and used in areas with low vibration. Excessive vibration can cause fluctuations in the horizontal plane, affecting measurement accuracy and zero calibration accuracy!
