Humidity experiment environment box capable of continuously weighing

Abstract

A humidity experiment environment box capable of continuously weighing comprises an electronic scale and an environment box, and the electronic scale comprises a bearing table, a leading-out type liquid crystal display screen and an operation panel. The environment box is placed on the upper surface of the electronic scale, the bearing table used for weighing is fixed in the environment box, the bearing table is connected with the leading-out type liquid crystal screen through a cable, the operation panel is connected with the leading-out type liquid crystal screen, and the temperature and humidity sensor is connected with the leading-out type liquid crystal screen. The leading-out type liquid crystal display screen can display time, the weight of a metered object and the temperature and the humidity in the environment box. The leading-out type liquid crystal display screen can be operated by an operation panel to set measurement parameters for continuous measurement, balance measurement or timing measurement, and a user can set the parameters according to needs. Compared with a traditional water release testing method, the method is simpler, more convenient and more accurate to operate.

Description

technical field [0001] The invention relates to a humidity experiment environment box capable of sustainable weighing, in particular to a test box capable of continuously measuring and recording quality, temperature and humidity, and belongs to the field of environmental test boxes. Background technique [0002] At present, the water release performance of porous water-absorbing materials under different humidity conditions is measured in the laboratory. According to the ASTME104 specification, the saturated surface-dried porous material is placed in an environmental chamber filled with saturated potassium sulfate, potassium nitrate and other salt solutions. However, there is no environmental chamber that can measure the quality and humidity in real time, so that the experimental data cannot be obtained timely and accurately during the water release measurement test, which affects the experimental process. At the same time, the humidity maintained by the saturated salt solut...

[0002] At present, the water release performance of porous water-absorbing materials under different humidity conditions is measured in the laboratory. According to the ASTME104 specification, the saturated surface-dried porous material is placed in an environmental chamber filled with saturated potassium sulfate, potassium nitrate and other salt solutions. However, there is no environmental chamber that can measure the quality and humidity in real time, so that the experimental data cannot be obtained in time and accurately during the water release measurement test, which affects the experimental process

At the same time, the humidity maintained by the saturated salt solution is greatly affected by the ambient temperature. When the weighing is taken out, the ambient temperature and humidity change, and the accuracy of the measured experimental results will be affected to a certain extent.
