Constant temperature and humidity laboratory

product name

Constant temperature and humidity laboratory/Constant temperature and humidity laboratory/Constant temperature and humidity room(Constant temperature and humidity laboratory)

application

Constant temperature and humidity laboratory suitable for aviationboatTest the performance indicators of various products, information electronic instruments, materials, electricians, electronic products, and various electronic components in high and low temperature or humid and hot environments.

Box Structure

The base of the constant temperature and humidity laboratory is made of 8 # channel steel welded into a mesh frame to withstand horizontal conditionschamberThe weight of the body and personnel test specimens without generating a chamberbodyThe bottom surface is uneven and cracked. Bearing capacity 200kg/square meter
The laboratory body (main body (shell)) is divided into six partsindividualThe room surface and a double opening door, with dimensions of 1800 × 2000 mm, are made of high-quality stainless steel plates for the inner lining (to prevent rusting of the inner wall under long-term humidity operation) and high-quality color steel plates (a domestic brand) for the outer lining. The insulation medium is polyurethane hard foam insulation, which is lightweight, resistant to resistance, and has excellent insulation performance,bigThe door material is also color steel platemakeCheng, the door handle is designed to open both inside and outside, allowing testers to freely open the door from the enclosed room.

Technical Parameter

Temperature range: -60 ℃~150 ℃ (alternating temperature range: -60 ℃~80 ℃)
Humidity range: 30-98% RH (capable of alternating humidity)linear measureRange: 45-98% RH
Wave uniformity: ± 0.5 ℃/± 2 ℃
Accuracy range:warmTemperature 0.1 ℃, humidity 1% RH, indication accuracy: temperature 0.1 ℃, humidity 1% RH

control system

Imported programmable touch LCD Chinese dialogue display, microcomputer integrated controller.
The temperature and humidity display control instrument adopts a fully imported large screen (5.7-inch LED display) from Japan, with simple screen operation, easy program editing, no need for button input, and direct touch options on the screen. Accuracy: 0.1 ℃ (display range).
Temperature sensor: PT100 platinum resistance thermometer.
Control method: thermal balance adjustmentwarmHumidity regulation method; All electrical appliances use Schneider series products.
humidlinear measureThe control adopts the P · I · D+S · S · R system for coordinated control of the same channel.
The constant temperature and humidity laboratory has the function of automatic calculation, which can immediately correct the temperature and humidity change conditions, making temperature and humidity control more accurate and stable.
The controller operation interface is available in both Chinese and English, and the real-time operation curve chart can be displayed on the screen.
It has a capacity of 120 programs, 99 segments per group, and 999 steps per segment that can be cycled. Each time interval is set tocalmThe maximum value is 99 hours and 59 minutes.
Data and TestingInspectionAfter the condition input, the controller has a screen lock function to avoid manual touch and shutdown.
Equipped with RS-232 or RS-485 communication interface, it can be programmed and monitored on a computerregardConduct the experiment process and perform functions such as automatic power on/off and printing curve data.
The controller has an automatic screen saver function, which better protects the LCD screen during long-term operation (making its lifespan longer).
In operation or setting, if an error occurs, it willcarryProvide warning alerts.
