HUDA plastic Humidity Chamber QT-E702-408B60 -60 ℃/408L

Introduction

This series of constant temperature and humidity testing machines are mainly used to simulate the harsh high temperature and low temperature that may be encountered in the transportation, storage and use of electronic instruments, new materials, electricians, vehicles, metals, electronic products, aerospace materials, etc. Or hot and humid environment; or high temperature, low temperature, humid heat alternating environment, test materials, accessories or equipment high temperature resistance, cold resistance, damp heat resistance and possible damage life reduction.

Features

(1) Box structure:

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

2. Enclosure Material: SUS304# (1.0mm thick) stainless steel plate is used.

3. Door handle: It adopts non-reaction, explosion-proof door handle, which is easy to operate, safe and reliable.

4. Insulation system: The insulation area is filled with ultra-fine glass fiber, and the connection parts of the inner and outer boxes are made of non-metallic high-low temperature resistant materials, which can effectively reduce temperature conduction; the door seal is made of refined silicon rubber, so that there is no aging under high-low temperature conditions And hardening phenomenon, the sealing is more reliable; the humidification method adopts isolated humidification.

5. Moving and positioning device: High-quality fixed PU movable wheels are installed at the bottom of the machine, which can easily move the machine to the designated position, and then fix the casters.

6. Sample rack: SUS304# stainless steel is punched and bent into a mesh shape, which is easy to use, and the distance between the material racks can be adjusted. The standard configuration is two pieces, and the samples are evenly distributed according to the load-bearing ≧ 20kg.

7. Test hole: open a Φ50mm test hole, and attach corresponding heat insulation accessories and special sealing soft plugs

8. Observation window: Double-layer vacuum strengthened glass is used, and the inner glued sheet-type conductive film is heated and defrosted, so that the test process can be clearly observed.

(2) Refrigeration system:

1. The refrigerating unit adopts French Taikang compressor and American DuPont environmental protection refrigerant (R404a), and adopts a binary low-temperature circuit system design, which is convenient for different temperature regions to use different compressors to work, so as to increase equipment.

2. The temperature and humidity control adopts the PID + SSR system to coordinate and control the same channel, with the function of automatic calculation, which can immediately correct the temperature and humidity changing conditions, making the temperature and humidity control more accurate and stable.

3. High-precision controllers are used for temperature and humidity, and the relative temperature and humidity performance can be set and displayed accurately, with a resolution of 0.1°C

(3) Heating and humidification system:

1. Nickel-chromium alloy high-speed heating electric heating wire is used for heating; 

2. High temperature completely independent system; 

3. Humidity adopts stainless steel tube with built-in nickel-chromium alloy high-speed heating electric heating wire and high-temperature magnesium oxide powder, which has fast response and long life. 

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

(4) Control system:

1. Adopt precision liquid crystal display programmable temperature controller; 

2. Intelligent digital display PID microcomputer temperature control instrument; 

3. Touch setting, digital and direct display, the humidity directly displays the percentage, and the temperature sensor adopts PT100 platinum resistance Tester. 

4. Temperature control adopts heat balance temperature adjustment method. 

5. The program test can be done with the precise liquid crystal display programmable temperature controller, and there can be multiple groups of multi-segment programming operations, the function of setting value and program optional, and the time can be set arbitrarily. 

6. The main electrical components of the equipment, such as circuit breakers and AC contactors, all use the "Chint" brand, and other electrical accessories use well-known domestic (CN) brands. 

7. Convenient data processing: It can be connected to a printer or 232 communication interface, has a USB data transfer interface (U disk), can be displayed on a computer, and print temperature, humidity and time curves, providing a strong guarantee for data storage and playback during the test process.

(5) Protection system:

Overall equipment overtemperature, fan overheat protection, overall equipment phase loss/reverse phase, refrigeration system overload, refrigeration unit overpressure, overall equipment timing, and other protections such as leakage, operation indication, and automatic shutdown after fault alarm.
