Introduction to constant temperature and humidity box

Constant temperature and humidity box is also called constant temperature and humidity machine, constant temperature and humidity experiment box, programmable damp and heat alternating test box, constant temperature machine or constant temperature and humidity test box. It is used to test the performance of materials in various environments and test various equipment The material has heat resistance, cold resistance, dry resistance and humidity resistance. It is suitable for testing the quality of products such as electronics, electrical appliances, mobile phones, communications, meters, vehicles, plastic products, metals, food, chemicals, building materials, medical care, and aerospace. The structure of the constant temperature and humidity box is roughly made of high-grade steel plate baking varnish or stainless steel with SUS 304# grain treatment in the outer box; the inner box is made of SUS 304# 8K mirror stainless steel plate, and the insulation layer is made of polyurethane integral foam, which is light, durable, and anticorrosive. The door is closed with magnetic tape, which has the advantages of beautiful appearance and high temperature control accuracy. The constant temperature and humidity box can be divided into single door constant temperature and humidity box and double door constant temperature and humidity box or walk-in constant temperature and constant according to common specifications Wet box.

Constant temperature and humidity box test size: 40 x 50 x 40CM (W x H x D) can be customized according to customer requirements.

Basic requirements of constant temperature and humidity box:

 This constant temperature and humidity box product meets GJB1032-90, GB2423.1-89, GB2423.2-89, GJB150.3-86, GJB150, product number: 4-86, GB/T13310-91, GB2423.10-95, IEC68-2-6 (FC) and other test standards and methods.

Working principle of constant temperature and humidity box:       

The constant temperature and humidity box consists of two parts: temperature adjustment (heating and cooling) and humidification. Through the rotating fan installed on the top of the box, air is discharged into the box to realize gas circulation and balance the temperature and humidity in the box. The data collected by the temperature and humidity sensors built in the box are transmitted to the temperature and humidity controller (micro Information processor) for editing, and issuing temperature and humidity adjustment instructions, which are completed by the air heating unit, condenser tube, and heating and evaporation unit in the water tank.

The temperature adjustment of the constant temperature and humidity test box is through the built-in temperature sensor of the box, collecting data, adjusting by the temperature controller (micro information processor), connecting the air heating unit to increase the temperature or adjusting the cooling solenoid valve to reduce the temperature in the box. To achieve the temperature required for control.
