The measurement range of liquid nitrogen digital temperature recorders usually varies depending on their design and application, but generally speaking, their measurement range usually includes the following aspects:
1. Low temperature measurement range
The boiling point of liquid nitrogen is -196 ° C, so the lowest temperature that liquid nitrogen digital temperature recorders can generally measure is usually -200 ° C to -100 ° C. Some high-end instruments can measure even lower temperatures, such as -270 ° C (close to absolute zero).
2. High temperature measurement range
Although liquid nitrogen digital temperature recorders are mainly used for low-temperature measurement, some instruments can also measure higher temperatures within a certain range, usually between -50 ° C and 200 ° C, and are suitable for monitoring environments with large temperature changes.
3. Accuracy and Resolution
Most liquid nitrogen digital temperature recorders have high measurement accuracy, typically ± 0.1 ° C or higher, and have a resolution of 0.01 ° C or 0.1 ° C.
4. Application Fields
This type of temperature recorder is widely used in low-temperature laboratories, liquid nitrogen storage, cold chain logistics, pharmaceutical storage, and other fields, requiring precise monitoring in extremely low temperature environments.
