YLS-7C Toe Volume Measuring Instrument is an upgraded product of the YLS-7B Toe Volume Measuring Instrument. This instrument retains the original advantages such as the backlight, hand rest bracket, water surface probe linkage device, and detachable measuring cup, while improving measurement accuracy. It has adopted a Chinese LCD display menu, facilitating the management of settings, calibration, and data recording. The user-friendly interface ensures clear and intuitive display of test data. The instrument has improved the interface method for PC connection, with a USB interface enabling convenient and quick connections. This instrument is highly practical, making complex experiments simple, convenient, and accurate.

Since the instrument is theoretically based on the buoyancy principle of "Archimedes' Law," it can be utilized for various purposes, such as measuring the volume of small animal organs, animal tumor volumes, and irregular small objects, allowing the instrument to fulfill its potential.

III. Precautions

1. The instrument should be kept clean. When not in use for extended periods, empty the water and store it in a ventilated, dry place.

2. After use, wipe the instrument clean promptly. Use a damp cloth with detergent for wiping; avoid using organic solvents, as they may damage the instrument's surface appearance.

3. Although the base of the measuring cylinder has been treated with passivation technology, avoid contact with strong acids and alkalis. If there is dirt, wipe it with a soft cloth dipped in detergent and rinse with clean water. When removing the measuring cylinder for cleaning, handle it with extra care to avoid breakage.

4. This instrument is a precision instrument and should be placed and used in an environment with minimal vibration. Excessive vibration may cause fluctuations in the water level, affecting measurement accuracy and zero calibration accuracy!!!
