      Description

      The digital bimetal thermometer changes the traditional thermal expansion metal spiral to drive the pointer to rotate to indicate the temperature, and directly converts the electrical signal of the temperature change into a number to display the temperature. It has the characteristics of high accuracy and no parallax. And it solves the shortcomings of mechanical instruments such as narrow range and large error.
      The digital bimetal thermometer uses micro-power consumption, low-voltage large-scale integrated circuits as the core device, and only one 1.5V5# battery can make the thermometer work continuously for more than 3 years. The outer shell of the thermometer is made of stainless steel and a waterproof and dust-proof fully sealed structure, which is especially suitable for working in humid and dusty environments. Can be widely used in food, pharmaceutical, textile, printing and dyeing, papermaking and other industries
