Constant temperature and humidity deformation tester

Abstract

The invention discloses a constant temperature and constant humidity deformeter. Detection equipment is arranged over materials to be tested, a side wall of an integrity formed by a square transparent closed box and a water storage tank is a cuboid side wall provided with a cavity, and an air heater, an air condenser and a gas temperature sensor are connected to the upper end of the cuboid side wall provided with the cavity respectively. Compared with the prior art, by the adoption of the design scheme, the constant temperature and constant humidity deformeter has the advantages that a saturated solution of used inorganic salt is easy to prepare and can be prepared and used repeatedly; a used electronic micrometer gauge is fixed to the outer side of a constant temperature and constant humidity box, a probe of the electronic micrometer gauge makes contact with the materials to be tested, wherein the materials to be tested are located on the inner side of the constant temperature and constant humidity box, and therefore real-time in-situ monitoring on deformation of the materials to be tested at the set temperature and humidity can be achieved. The constant temperature and constant humidity deformeter is high in accuracy, good in repeatability and capable of performing real-time in-situ monitoring.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a constant temperature and humidity deformation measuring instrument. Background technique [0002] For most porous inorganic non-metallic materials, such as gypsum, cement concrete, etc., it is easy to change the size of the material itself, that is, deformation, due to changes in temperature or humidity in the environment in which it is used. Therefore, it will have a broad market prospect to develop an instrument that can measure the deformation of materials under the condition of set temperature / humidity. [0003] At present, the following two methods are usually used in laboratories to measure the deformation of materials under set temperature / humidity. Method 1: First use the deformation measurement equipment to test the initial size of the specimen, then put the specimen into the constant temperature and humidity box, set the required temperature and humidity, and then maintain t...
