The temperature measuring element inside this product adopts our company's patented ceramic wrapped integral sintered PT100 temperature measuring element, with a temperature measuring range of -60 ℃ to 250 ℃, accuracy of Class A, diameter of 3 × 70mm, and response time of less than 3s. Due to the need to measure low temperatures of -60 ℃, the packaging takes into account the issue of preventing moisture from entering and freezing at low temperatures, resulting in a longer service life.
