Programmable constant temperature and humidity chamber

1、 Product Introduction

This series of products has constant temperature and humiditytest chamberIt is mainly used to simulate harsh high temperature, low temperature, or humid and hot environments that may be encountered during transportation, storage, and use of electronic instruments, new materials, electricians, vehicles, metals, electronic products, aerospace materials, etc; Under high temperature, low temperature, humid and hot alternating environments, inspect the high temperature, cold resistance, humid and hot resistance performance of materials, accessories or instruments and equipment, as well as the possible reduction of damage life, etc.

IIProduct Features

（1） Box structure

1. Inner box material: SUS304 is used#（1.0Mm thick）Stainless steel plate has the advantages of acid resistance, corrosion resistance, and easy cleaning;

2.outsideBox material: Cold rolled steel plate with baking paint treatment, 1.0Mm thick(Box body dark gray, box door sky blue);

3. Door handle: Adopting non reactive, explosion-proof door handle, easy to operate, safe and reliable;

4.Insulation system: The insulation area is filled with ultra-fine glass fiber, and the connection between the inner and outer boxes is made of non-metallic high and low temperature resistant materials, effectively reducing temperature conduction; The sealing of the box door is made of refined silicone rubber, so that there is no aging or hardening phenomenon under high and low temperature conditions, and the sealing performance is more reliable; The humidification method adopts isolated humidification；

5.Mobile and positioning device: High quality fixed type installed at the bottom of the machinePU activity wheels, which can easily move the machine to a position and fix the casters afterwards；

6.Sample rack: usingSUS304 # stainless steel punched and bent into a mesh shape, easy to use, adjustable spacing between material racks, standard configuration of two pieces, samples according to load-bearing capacity ≥20kg evenly distributed；

7.Test hole: openA test hole with a diameter of 50mm, accompanied by corresponding insulation and heat insulation accessories, as well as a dedicated sealing soft plug；

8.Observation window: Double layer vacuum strengthened glass is used, and the inner laminated conductive film is heated and defrosted to clearly observe the test process.

（2） Freezing system

1.The refrigeration unit adopts French Taikang compressor and usesDuPontEnvironmentally friendly refrigerant（R404a）Adopting a binary low-temperature circuit system design, it facilitates the use of different compressors for power in different temperature ranges to increase equipment capacity；

2.Temperature and humidity control adoptsP. The I.D+S.S.R system coordinates and controls the same channel, with automatic calculation function, which can immediately correct the temperature and humidity change conditions, making temperature and humidity control more accurate and stable；

3.High precision controllers are used for both temperature and humidity, with precise display settings for relative temperature and humidity performance, and a resolution of up to0.1℃.

（3） Heating and humidification system

1.Heating adopts nickel chromium alloy high-speed heating electric wire;

2. High temperature independent system;

3. The humidity is achieved by using stainless steel tubes with nickel chromium alloy high-speed heating wires and high-temperature magnesium oxide powder, which have a fast reaction time and long service life;

4. The heating and humidification systems are independent, and there is an automatic water replenishment device for humidity.

（four）Control system

1.Adopting precision LCD display programmable temperature controller;

2.Intelligent digital displayPID microcomputer temperature control instrument;

3.Touch sensitive settings, digital and direct display, humidity directly displays percentage, temperature sensor adoptsPT100 Platinum Resistance Tester；

4.Temperature control adopts thermal equilibrium temperature adjustment method；

5.useprecisionThe LCD display programmable temperature controller can be used for program testing, with multiple sets and segments of programming operations, adjustable values and programs, and the ability to set time arbitrarily；

6.The main electrical components of the equipment, such as circuit breakers and AC contactors, are all made ofZhengtai "brand, other electrical accessories use domestic brands；

7.Convenient data processing: can be connected to a printer or232 communication interface, with USB data transfer interface (USB flash drive), displayed on a computer and printed with temperature, humidity, and time curves, providing strong guarantee for data storage and playback during the experimental process.
