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. 【Features】 1. The host is embedded with a touch screen window system tablet computer; 2. The host comes with a large-capacity lithium battery for uninterrupted power supply; 3. Automatic acquisition and data storage 4. The device supports WeChat data transmission (optional) 5. Using platinum resistance as temperature sensing element, good stability; 6. The host system is upgraded and transformed, and the operation is more convenient; 7. 3 alarm modes, 2 points of public alarm relay output; 8. Each input channel is provided with surge and overvoltage protection, and unused channels can be closed arbitrarily; 9. Strict anti-interference design to suppress rapid burst interference and other electromagnetic interference generated by on-site relays, contactors, etc., and the anti-interference ability reaches level III; 10. Automatic compensation for time drift and temperature drift; 11. Each channel independently sets the digital filter time constant to improve the display stability value, and each channel independently sets the zero point and full scale correction, 12. The measurement and control software can be applied to the detection of the heat flow meter method or the detection of the calibration hot box method. 13. The equipment adopts special software, more accurate dynamic analysis method for data processing and calculation. 【technical parameter】 1.
