Mobile instant temperature monitoring device

The present invention relates to a monitoring device, and more particularly to a mobile instant temperature monitoring device for viewing a change in heat treatment of a sample.

The existing high-temperature furnace is widely used for heat treatment such as sintering, quenching or annealing of a sample, so that the user can change the heating power of the high-temperature furnace before and after the heat treatment. To control the temperature rise and fall in the high temperature furnace, and then to heat or cool the sample. However, it takes a certain time to adjust the heating power of the high-temperature furnace until the temperature in the high-temperature furnace is actually raised to the required temperature, which results in a certain temperature limit of the high-temperature furnace, once the user wants to rapidly heat the sample. In the heat treatment, the heating rate of the high temperature furnace cannot be directly adjusted to achieve the desired heating rate, and thus the existing heat treatment method still needs to be improved.

Accordingly, it is an object of the present invention to provide a mobile instant temperature monitoring device that provides rapid temperature rise of the sample and immediate observation of sample changes.

Therefore, the mobile instant variable temperature monitoring device of the invention is applicable A sample is heat treated and includes a high temperature furnace, a feed unit, and an observation unit. The high temperature furnace defines a heating space and includes an observation port communicating with the heating space, the heating space having a low temperature region and a high temperature region. The feed unit includes a stage for the sample to be placed and movable between the high temperature region and the low temperature region. The observing unit includes an image capturing module capable of capturing an image of the sample through the observing port, and a display module capable of displaying the image captured by the image capturing module.

The effect of the invention is to control the movement of the sample between the high temperature region and the low temperature region by controlling the movement of the stage to adjust the temperature rise history of the sample, and to enable the sample to rapidly heat up during the movement without limitation. In the heating rate of the high temperature furnace, in addition, during the movement, the user can also timely watch the change of the sample during the movement through the observation unit.
