Notice:
● Do not put the sensor in the liquid or expose the sensor to sunlight
● Exposure to extreme working conditions or chemical vapor will affect the accuracy of the instrument or even damage the instrument
● When measuring the chemical vapor temperature with a sub-meter, the diffusion of chemicals in the sensor results in a decrease in instrument accuracy and sensitivity, allowing the instrument to prevent a slow recovery in a clean environment for a long time.
