Digital Thermometer Scope

The digital thermometer adopts imported chip assembly with high precision and high stability, error ≤0.5%, internal power supply, micro power consumption, stainless steel casing, strong protection, beautiful and exquisite.

The digital thermometer adopts imported high-precision, low-temperature drift, ultra-low-power integrated circuit and wide-temperature liquid crystal display. The built-in high-energy battery can work continuously for ≥5 years without laying power supply cable. It is a kind of high precision, good stability and applicability. Strong new on-site temperature display. It is an ideal substitute for traditional on-site pointer bimetal thermometers, and is widely used in various industrial and mining enterprises, universities and research institutes.

The number of temperatures in our daily production and life in real-time contact, but it is invisible, only the feeling can only feel the approximate temperature value, the traditional pointer-type thermometer can indicate the temperature, but the accuracy is low. The use is not convenient enough, the display is not intuitive enough, and the appearance of a digital thermometer allows people to intuitively understand how much temperature they want to know.

Digital thermometers use temperature-sensitive components, ie temperature sensors (such as platinum resistors, thermocouples, semiconductors, thermistors, etc.), to convert temperature changes into changes in electrical signals, such as changes in voltage and current, temperature changes, and electrical signals. There is a certain relationship between changes, such as linear relationship, certain curve relationship, etc. This electrical signal can be converted into a digital signal by using an analog-to-digital conversion circuit, that is, an AD conversion circuit, and the digital signal is sent to a processing unit such as a single chip microcomputer or a PC. Then, the processing unit associates the digital signal with the temperature through internal software calculations to become a displayable temperature value, such as 25.0 degrees Celsius, and then displays it through a display unit such as an LED, an LCD or a computer screen. This completes the basic temperature measurement function of the digital thermometer.

The digital thermometer differs according to the sensor used, the AD conversion circuit, and the processing unit. Its accuracy, stability, and temperature range are different. It is necessary to select a digital thermometer that meets the specifications according to the actual situation.

Digital thermometers are hand-held, disk-mounted, and medically small.
