4results about How to "Accurate humidity" patented technology

This application relates to an immunohistochemistry humidifier with precise and stable internal humidity. Specifically, an air pump and a humidity sensor are installed inside the humidifier. The air pump circulates air within the humidifier, causing the humidity inside to rise rapidly. The humidity sensor detects the humidity level inside the humidifier. Together, these two components enable the humidifier to quickly reach an ideal humidity environment, thereby improving the quality of sample processing and ensuring the accuracy of subsequent experimental or detection results.

The invention discloses a conveying box purging device, a conveying box storage device and a conveying box purging control method.According to the conveying box purging device, a gas outlet pipeline is provided with a first branch and a second branch, the first branch is connected with a suction device, and the control device can control the suction device to suck gas before protective gas is introduced into a conveying box; according to the conveying box, gas in the conveying box is rapidly extracted, protective gas does not need to be used during extraction, waste of the protective gas can be reduced, when the protective gas is introduced subsequently, the protective gas can be introduced into the conveying box more rapidly due to low pressure in the pipeline and the conveying box, the blowing speed of the protective gas is increased, and the blowing efficiency is improved; after the humidity and / or oxygen concentration in the conveying box meets the requirement, under the condition that the gas outlet pipeline is closed, the protective gas is supplied at low flow, and when the protective gas cannot be maintained, purging is carried out at relatively large third flow, so that the atmosphere of the protective gas in the conveying box can be maintained to the maximum extent, and the consumption of the protective gas is reduced.

The utility model discloses a temperature and humidity controllable curing box for cement setting time detection, and relates to the technical field of cement quality inspection, the temperature and humidity controllable curing box comprises a curing box unit and a cooling unit, the curing box unit comprises a shell, a door body is arranged on one side of the shell, a control device is arranged on one side of the shell, a heating pipe is fixedly installed in the shell, and the heating pipe is connected with the cooling unit. A ventilation fan is fixedly installed on the back face of the shell. The heating area and the cooling area are separated, so that temperature control is more accurate, two tests with larger spans can be carried out at one time, efficiency is higher, and meanwhile, the hot area and the cold area are separated, so that the problem of severe humidity fluctuation caused by evaporation and condensation of condensate water during temperature switching can be avoided; the condensate water can flow into the integrated pipe and the guide pipe through the inclined plate in the condensate water connecting pipe and finally enters the water tank, and the water can be sprayed and humidified through the ultrasonic humidifier in the water tank, so that the condensate water is recycled, and the condensate water is prevented from dropping into cement to influence the test result of the cement.

The utility model discloses an incubator with an accurate humidity adjusting function, which comprises a water storage box, a rotating frame, a hood and a main machine part, and the space in the hood on the upper side of the rotating frame is an incubation bin; the main machine part comprises a machine shell, a circuit bin is arranged on the upper portion of the machine shell, a working bin is arranged on the lower portion of the machine shell, and a humidity sensor is arranged on the side of the machine shell. Circulating air inlets are formed in the periphery of the bottom of the working bin and located beside the water absorption medium, a ventilation opening is formed in the motor support partition plate, circulating air outlets are formed in the periphery of the top of the working bin and communicated with the hatching bin, and therefore an inner circulating air channel is formed. An outer circulation air duct is arranged on one side of the top of the working bin and provided with an electric exhaust gate. The incubator has the function of accurately adjusting the humidity, and the humidity of air in the incubation bin can be accurately and stably controlled through the cooperation of the humidity sensor, the fan, the peristaltic pump, the water absorption medium, the inner circulation air duct and the outer circulation air duct.
