The utility model relates to the field of oxygen measurement, and discloses an oxygen concentration measuring device with a filtering function, which comprises a filtering valve seat, a filter and an oxygen sensor, and the filtering valve seat is provided with an air inlet and a first airflow channel; an inlet of the filter is communicated with the air inlet; and an inlet of the oxygen sensor is communicated with an outlet of the filter through the first airflow channel. The device has the beneficial effects that the filter is arranged to filter moisture and other impurities in the reflow furnace, so that the filtered airflow enters the first airflow channel from the outlet of the filter and then enters the oxygen sensor from the first airflow channel for oxygen content detection; moisture and other impurities in the reflow furnace are prevented from entering the oxygen sensor, and the quality and the service life of the oxygen sensor are ensured.

This disclosure discloses a method, apparatus, and system for controlling multiple air conditioning devices, as well as air conditioning equipment and a storage medium. The method includes: determining whether the multiple air conditioning system is in a state without central control; when the system is in this state, acquiring the average ambient temperature and a set temperature; determining the number of air conditioning devices to be turned on based on the average ambient temperature and the set temperature; and determining whether the current air conditioning device needs to operate based on the number of devices turned on and the operating time of all air conditioning devices in the system. The multiple air conditioning system includes a central control device and multiple air conditioning devices, and the control method is executed by a control device located on the current air conditioning device. In the state where the multiple air conditioning system is in a state without central control, the air conditioning devices within the system can automatically control their on / off states and maintain the ambient temperature.

The application discloses a graphite sample clamp, a graphite furnace and a graphite oxidation corrosion test bench, and relates to the technical field of graphite sample clamps. The graphite sample clamp comprises a first clamping piece and a second clamping piece. The first clamping piece comprises a first clamping piece body and a protruding part arranged on the first clamping piece body. A through hole is arranged on the graphite sample. The second clamping piece comprises a second clamping piece body and a recessed part arranged on the second clamping piece body. The protruding part of the first clamping piece passes through the through hole of the graphite sample and enters the recessed part of the second clamping piece to be detachably connected with the second clamping piece. The graphite sample is clamped between the first clamping piece body and the second clamping piece body.
