Does the temperature of the object being measured need to be recorded, alarmed, and automatically controlled? Is long-distance measurement and transmission required?
What are the requirements for the temperature measurement range and accuracy?
Is the size of the temperature sensing element appropriate?
In situations where the temperature of the object being measured changes over time, can the hysteresis of the temperature sensing element meet the measurement requirements?
Will the environmental conditions of the object being measured damage the temperature sensing element?
Price and ease of use.
