利来w66下载报道Walk-low temperature test chamber_利来w66下载官网资讯

, high and low temperature test chamber can provide the industry large parts, semi-finished products, finished products are temperature and humidity testing which is mainly composed of control panel,

Power distribution cabinet, insulation library board, blower, heater, humidifier, board composition and freezer.

, box base plate unit, volume can be arbitrarily enlarged, easy assembly and disassembly, according to customers need to design and expanding plant migration.

the wing, horizontal centrifugal air diffusion vertical heat exchange circulating system, to avoid any dead end so that the indoor temperature and humidity distribution.

, freezer with Europe and the United States imported compressor, and the use of environmentally friendly refrigerant, design two yuan low temperature refrigeration system using a loop system, and

In different temperature domains with different compressor working longer equipment life.

, the control system can be selected by the RS-232 interface to connect with computer, the user can design programs on a computer screen, collect test data and

Call recording, program execution, the remote machine switch function.

, occurrence of abnormal condition, the controller screen instantly and automatically display the fault state, cut off the power switch, and provide troubleshooting method.

, with timing mark contact function, can make the operation process, the external output control contact, to provide users with dynamic test and computer

Monitor.

, base plate made of stainless steel and high quality steel sheet varnish material quality, firm structure, waterproof and beautiful.

, control mode and characteristics: balanced temperature control system (BTHC) special design of the ceiling fan forced circulation system, based on P.I.D.

Control of SSR, the heating and humidifying system is equal to the heat and moisture loss, so it can be long-term and stable use.

Temperature Control System

Controller

Chinese imports of programmable LCD touch interactive display, microcomputer integrated controller.

Temperature display and control instruments used (Japan) full import of large screen (7-inch LED display), a simple screen operation and programming easy, no keystrokes directly touch screen option. Accuracy: 0.1 ℃ (display range).

Temperature control using the same channel coordinated control P · I · D + S · S · R system.

With automatic calculation function can be immediately corrected temperature conditions, the temperature control is more precise and stable. After the input data and test conditions, the controller has a screen lock function to avoid human touch and downtime.

Program has 120 groups, each 99 segments, each cycle can capacity 999 steps, each time setting a maximum of 99 hours and 59 minutes.

With RS-232 or RS-485 communication interface, the program can be designed on a computer, monitor the testing process and execute Switcher, print curve data and other functions.

The controller has a screen automatic screen saver function, in the long run the state better protect the LCD screen (make it longer life).
In the operation or setting, such as when an error occurs, an alert will provide fast number.

Material

Carton Material

Chamber body base with 8 # channel welded into an intensive framework conditions in order to be able to withstand in the horizontal chamber body weight and personnel of the specimen, without generating chamber bottom surface uneven and cracking. Withstand the force of 200kg / per square meter
Laboratory chamber body [body (shell)] is divided into six rooms and one pair of decent rooms open door body, the size of 1800 × 2000 mm, chamber liner material is high quality stainless steel (to prevent long running in humidity under the inner wall of rust), outside the gall of quality steel (domestic brand), polyurethane insulation medium is rigid foam insulation, light resistance, fight, good insulation, doors made of the same material as the color steel door inside and outside handle open type, in order to test personnel from the freedom to open the door to the room closed.

Within the box material

SUS304Stainless steel quality light board

Insulation Material

Polyurethane rigid foam, ultra-fine glass fiber cotton

Door insulation

Double resistant to high temperature aging silicone rubber door seal

Observation window

The bright lights to keep the box, and the use of heating element embedded glass, clear observation box at any condition. Observation window size: 400 * 500mm

Standard configuration

Test leads holes φ50mm1 months (openings available upon request)

Security

Leakage, short circuit, over temperature, motor overheating, over-pressure compressor, overload, over-current protection
