3a Current Environment Test Box Constant Temperature And Humidity Test Chamber

Constant temperature and humidity test chamber JD-8001-80L

Product introduction:

The constant temperature and humidity test chamber is used to test various performance indexes of electronic products, materials, electricians and instruments under high and low temperature or humid heat environment. Why do electronic products have to be tested in constant temperature and humidity environment? With the rapid development of modern industrial technology, the application fields of electronic and electrical products are becoming more and more extensive, and the environmental conditions experienced are becoming more and more complex. Only by properly stipulating the environmental conditions of the product and properly selecting the environmental protection measures of the product can the product be protected from damage during storage and transportation, and safe and reliable during use. Therefore, the artificial simulation environmental test of electronic and electrical products is to ensure that it is safe and reliable in all aspects of production, transportation and use. Manually simulating environmental testing of electronic and electrical products before leaving the factory is an indispensable part of ensuring quality. Therefore, it is important that environmental test conditions, test methods, and test equipment meet standards. The constant temperature and humidity test chamber is one of the main tests of artificial three-proof, and its application is more and more extensive. It is also valued by more and more military products, scientific research units, universities and other research units.

This series of constant temperature and humidity test chambers is suitable for the reliability test of various industrial products. It has the characteristics of temperature control precision and wide control range. The performance index conforms to GB5170.2.3.5.6-95 "Basic parameters verification method for environmental test equipment of electrical and electronic products". Requirements for low temperature, high temperature, constant damp heat, alternating wet heat test equipment.

Product configuration:

Main configuration: The main controller adopts the imported Korean TEMI580 Chinese and English dual-circuit high-precision liquid crystal display touch temperature and humidity controller. The controller adopts a liquid crystal display to display setting parameters, running time, heater working status, and PID parameter self-tuning function. The control program is compiled in a man-machine dialogue mode, and the automatic operation function of the refrigerator can be realized only by setting the temperature. The control system has a complete detection device that can automatically perform detailed fault display and alarm..

User program capacity: 120 groups × 120 segments.

Operation mode: program running, fixed value running.

Program time: IS-99H can be selected. Controllable temperature range: -40 ° C ~ +150.0 ° C.

Controllable humidity range: 20%~98% RH (20°C below 90°C humidity is not displayed).

Controller accuracy: Temperature: 0.1 ° C / humidity 0.5 RH.

Controller resolution: Temperature: 0.1 ° C / humidity 0.5 RH.

Timer: The device working time accumulation timer.

Communication interface: configure 485-232 and USB communication interface and running software. (optional)

Temperature sensor: The temperature sensor is made of DIN PT-100Ω SUS#316 stainless steel (platinum induction).

Alarm function: Independent over-temperature protector and buzzer will automatically make a sound if there is a fault.

Time device: Fixed condition can set time 0 - 9999 H, fixed or alternating conditions can be set arbitrarily.

Fault prompt: With nine-point fault warning and simple maintenance method (TROUBLE SHOOTING), the fault is not ruled out.

Other functions: liter. Cooling can be used for slope control and has the function of self-correcting temperature reference point. Temperature control adopts P.I.D. + S.S.R. system synchronous coordinated control, which can improve the stability and life of control components and interfaces. (Japan Omron). It has the function of P.I.D. automatic calculation, which can reduce the inconvenience caused by artificial setting.
