Constant-weight measuring equipment

Abstract

The invention discloses constant-weight measuring equipment which comprises a controller and a first room. The first room comprises a first temperature zone chamber, a constant temperature and constant humidity chamber, a temperature control device, a constant temperature and constant humidity control device, a sealing cover, a sealing cover driving device, a sample tray assembly, a first drivingdevice, a sealing lid and a sample tray transferring device, wherein the first temperature zone chamber is provided with an inlet and outlet, a weighing device is arranged in the constant temperatureand constant humidity chamber, the temperature control device is used for controlling the temperature in the first temperature zone chamber and is in communication with the controller, the constant temperature and constant humidity control device is used for controlling the temperature and humidity in the constant temperature and constant humidity chamber and is in communication with the controller, the sealing cover covers the weighing device, the sealing cover driving device is used for driving the sealing cover to move, the sample tray assembly comprises a first connecting shaft and a sample tray set, the first driving device is connected with the first connecting shaft, the sealing lid is in sealing connection with the first connecting shaft, the sealing cover is hermetically fixed tothe inlet and outlet when the sample tray set moves into the first temperature zone chamber, the sealing lid is separated from the inlet and outlet when the sample tray set moves into the constant temperature and constant humidity chamber, and the sample tray transferring device is used for transferring samples to the weighing device. The constant-weight measuring equipment solves the problem of low measurement precision in sample measurement.

Description

technical field [0001] The invention relates to a device for measuring the weight of objects, in particular to an improvement of the structure of a constant weight measuring device. Background technique [0002] When measuring samples in existing experiments, the samples are generally evaporated and heated in a compartment first. After the evaporation and heating are completed, the samples taken out are manually put into a constant temperature and humidity measurement room for the samples to be heated. Measurement in a constant temperature and humidity environment, but after the sample is taken out, it will inevitably be affected by the temperature and humidity in the external environment, it will absorb part of the water, and the temperature will also change when it is affected by the external environment, eventually resulting in the measured Sample results are inaccurate and sample measurement accuracy is low. [0003] The above information disclosed in this background te...
