Temperature and humidity meter verification equipment

The utility model relates to the technical field of instrument verification equipment, in particular to hygrothermograph verification equipment which comprises an equipment body, a supporting mechanism is installed in the equipment body, a photographing mechanism is arranged on one side of the equipment body, and the supporting mechanism comprises a driving assembly and a supporting assembly. The device has the beneficial effects that when the device is used for calibrating the hygrothermograph, the supporting frame matched with the hygrothermograph is placed on the flange plate, then the supporting base and the flange plate are fixed through the connecting bolts, and the driving assembly and the supporting assembly are connected through the connecting bolts, so that a calibrator can conveniently disassemble and assemble the supporting frame; therefore, the application range of the device is enlarged. When temperature and humidity values are observed, the driving motor drives the transmission shaft to rotate
