N type thermocouple is commonly used in a wide range of applications because they are accurate, reliable, and have a wide temperature range. They can measure temperatures from -270°C to +1300°C (-454°F to 2372°F), making them suitable for use in both high- and low-temperature environments. N type thermocouple is often used in conjunction with temperature controllers or other control systems to maintain accurate and stable operating conditions. This is also used in many industrial processes to optimize production and reduce energy consumption.
