Shanghai walk-in humidity test chamber

Shanghai walk-in humidity test chamber

System Introduction

This series of environmental experiment boxes can provide a simulated environment for users to inspect and test electronic and electrical components, spare parts, or experimental departments in related industries, providing conditions for the accuracy and repeatability of test data. This product has simple operational performance and reliable equipment performance, a convenient measuring device, a temperature and humidity controller, and an advanced Chinese LCD display touch screen. It can perform various complex program settings, and the program settings are set in a dialogue mode, making the operation simple and fast. It can achieve automatic operation of the refrigeration machine, maximize automation, reduce the working time of operators, and can automatically start, stop, and operate at any time. The work of each system (fan, refrigeration dehumidification, heating, humidification) is centrally controlled by the touch screen human-machine interface. The overall assembly is carried out at the customer's end, with convenient transportation and placement, and on-site debugging and acceptance are carried out at the customer's end to ensure the performance of use at the customer's end; High degree of structural integration, short assembly and debugging time on the client side; Scientific air circulation design ensures even indoor temperature and humidity, avoiding any dead corners; A complete safety protection device avoids any potential safety hazards and ensures the long-term reliability of the equipment; Each product is customized according to customer requirements, ensuring the efficiency and energy saving of the equipment.

Shanghai walk-in humidity test chamber

reference standard

Environmental testing requirements for temperature and humidity in GB/T2423-2001 standard;

The price of the constant temperature and humidity test chamber includes heating, humidification, and dehumidification systems

1. Heating is achieved through the use of heating wires, and solid-state relays are used for the execution components; Humidifier adopts water evaporation method (external humidification), equipped with water cut-off protector, automatic water level controller, and automatic water filling device. Dehumidification adopts condensation method and is equipped with a dehumidification evaporator, which condenses the water vapor in the air inside the working room into water on the dehumidification evaporator and discharges it outside the box to reduce the relative humidity of the working room.

2. The humidity sensor adopts an imported capacitive sensor. Compared with the "dry wet bulb" method, it is more suitable for conducting long-term temperature and humidity tests because there is no need to worry about the wet bulb water replenishment system, water quality, and other issues, and there is no need to frequently replace the yarn cover.
