HUDA laboratory Humidity Chamber QT-E702-100K40 -40 ℃/100L

Introduction

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

Features

(1) Box structure:

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

2. Enclosure Material: cold-rolled steel plate baking paint, 1.0mm thickness (dark gray of the box body, sky blue of the box door).

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

4. Thermal insulation system: ultra-fine glass fiber is used to fill the insulation area, and the connecting parts of the inner and outer boxes are made of non-metallic high-low temperature resistant materials to effectively reduce temperature conduction; the door is sealed with refined silicone rubber, so that there is no aging and hardening phenomenon under high-low temperature conditions, and the sealing is more reliable; the humidification method adopts isolated humidification.

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

6. Sample holder: SUS304# stainless steel punching and bending into a net, easy to use, the spacing between the material racks can be adjusted, two pieces are standard configuration, and the samples are evenly distributed according to the load-bearing ≧ 20kg.

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

8. Observation window: double-layer vacuum strengthened glass, inner glued sheet conductive film heating and defrosting, clear observation of the test process.

(2) Refrigeration system:

1. The refrigeration unit adopts French Taikang compressor, and uses DuPont environmentally friendly refrigerant (R404a) of the United States, and adopts a two-element low-temperature circuit system design, which is convenient for different compressors to work in different temperature ranges to increase equipment.

2. The temperature and humidity control adopts the P.I.D + S.S.R system with the same channel coordinated control, which has the function of automatic calculation, which can immediately correct the temperature and humidity change conditions, so that the temperature and humidity control is more accurate and stable.

3. The temperature and humidity are all controlled by high-precision controllers, and the relative temperature and humidity performance is accurately set and displayed, with a resolution of 0.1°C

(3) Heating and humidification system:

1. Nichrome alloy high-speed heating wire is used for heating; 

2. High temperature completely independent system; 

3. The humidity adopts stainless steel pipe, built-in nickel-chromium alloy high-speed heating wire and high-temperature magnesium oxide powder, which has fast reaction and long life. 

4. The heating and humidification systems are completely independent, and the humidity has an automatic water replenishment device.

(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, humidity directly display percentage, temperature sensor using PT100 platinum resistance Tester. 

4. The temperature control adopts the thermal balance temperature control method. 

5. The programmable temperature controller with precision liquid crystal display can be used to do program tests, and there can be multiple groups of multi-segment programming operations, fixed values and programs are optional, and the time can be set arbitrarily. 

6. The main electrical components of the equipment, such as circuit breakers and AC contactors, are all under the brand of "CHINT", and other electrical accessories are made of domestic (CN) familiar brands. 

7. Convenient data processing: it can be connected to a printer or 232 communication interface, with a USB data transfer interface (U disk), displayed by a computer, and printed with temperature, humidity and time curve, which provides a strong guarantee for the storage and playback of data in the test process.

(5) Protection system:

The overall equipment is over-temperature, the fan is overheated protection, the overall equipment is under-phase/reversed-phase, the refrigeration system is overloaded, the refrigeration unit is overpressurized, the overall equipment is timed, and there are other protections such as leakage, operation indication, and automatic shutdown after fault alarm.
