The instrument supports the box-locking method that most experts currently support for detection. The device is upgraded on the original basis and has a built-in touch-screen tablet computer, which makes the operation more concise. The built-in high-capacity lithium battery can realize continuous data collection in the case of short-term power failure to ensure the integrity of the data. The WeChat data transmission function (optional) is also added, which mainly includes a temperature and heat flow inspection recorder, 4 heat flow meters, 12 platinum resistance resistors, and a standard line of 10 meters.
The instrument adopts a new type of single-chip microcomputer system and an instrument amplifier with high stability, low drift and low noise. At the same time, platinum resistance is used as a temperature sensor, and a control and acquisition software has been developed, which can achieve automatic acquisition, storage and automatic control with the help of a computer. , Automatic calculation and report function.
