There are various types of electric heating furnaces widely used in factories, mines, and research institutions for heat treatment, drying and solidification, temperature experiments, and other constant temperature heating. Electric heating furnaces can be divided into two types: 1. Natural convection furnaces; 2 electric blast furnaces; The temperature control range of the touch screen digital paperless recorder is from room temperature to thousands of degrees. During the temperature control process, it is necessary to record temperature changes at any time, and an effective data recording method is essential. Use a temperature regulator or measuring instrument with communication function to record data in a flash memory card

With China's entry into the WTO, the country's requirements for product quality, safety, and other aspects have become increasingly strict. For household appliances to circulate in the market, they must pass 3C certification, and temperature rise testing is an important testing item for major inspection bureaus or certification centers. In the national standard GB4706.1-2005/IEC60335-1:2004, there are provisions regarding heating and winding temperature rise, such as "11.1 In normal practice, appliances and their surrounding environment should not reach excessively high temperatures;

In the instrumentation industry, there are two types of instruments based on different screens. We all know that there are instruments with digital displays, and another type is instruments with liquid crystal displays.

The CJ3100 series paperless recorder and CJ6000 series paperless recorder are applied in chemical, food and beverage, petrochemical, semiconductor, alloy, automation factory and environmental monitoring or laboratory monitoring, recording and numerical calculation.
