    The second-grade standard water-in-glass thermometer measures temperature by utilizing the principle of thermal expansion and contraction of water-in-glass within the sensing bulb and capillary. It comes in two structures: inner scale and rod style. Primarily used as a standard for calibration work, it can also be used for temperature measurement. The measurement range is from -30℃ to +300℃, with a graduation of 0.1℃ and a zero-point scale.
