Low-temperature Temperature Sensor

The low-temperature thermometer uses thermocouples or thermistors to detect the surface temperature of objects ranging from -200℃ to -50℃, converting electrical signals into a digital display. It is used to monitor low-temperature environments such as freezing equipment and liquid nitrogen storage, ensuring that materials remain stable within the set temperature range.
