Red Liquid Rod Shaped Thermometer Leg Length

[Features]
・ Compared to general bar thermometers, the overall length and scale (leg) are longer, so it is suitable for inserting into various tanks and machinery such as factories to measure the internal temperature.
・ Normally, the thermometer is calibrated as if all of the mercury is at the same temperature, but the thermometer with immersion line measures the temperature by immersing it in the temperature measuring object up to the immersion line.
