Red Liquid Rod Shaped Thermometer Leg Length

[Features]
· Since the total length and the part under the scale (legs) are longer than an ordinary rod thermometer, it is suitable for measuring the internal temperature by insertion to various tanks or machines in factories, etc. Normal thermometers are graduated as if all the mercury is the same temperature, but thermometers with immersion lines are dipped into the measurement target up to the immersion line before measurement.
