Constant temperature and humidity test chamber is a kind of experimental equipment used to simulate the performance and durability test of articles under constant temperature and humidity conditions. Similar to the constant temperature and humidity chamber, the constant temperature and humidity chamber can control the set temperature and humidity conditions to test the performance and durability of the item under these conditions. Constant temperature and humidity test chamber is usually used in scientific research, production and quality management fields.

طريقة المعايرة
معايرة درجة الحرارة: Place the thermometer in the laboratory and set the laboratory to a known temperature. بعد الانتظار لبعض الوقت, the thermometer reading is compared with the temperature reading displayed in the experiment chamber. إذا كان هناك فرق, مطلوب تعديل المعايرة.

معايرة الرطوبة: Use a humidity calibrator to place it in the chamber and set the chamber to a known humidity. بعد الانتظار لبعض الوقت, the humidity calibrator reading is compared with the humidity reading displayed in the experiment chamber. إذا كان هناك فرق, مطلوب تعديل المعايرة.

معايرة توحيد المعدات: Place several thermometers or hygrometers inside the test chamber and set the chamber to a known temperature or humidity. بعد الانتظار لفترة من الوقت, قارن القراءات عند كل نقطة قياس لمعرفة ما إذا كانت متسقة. إذا كان هناك فرق, مطلوب تعديل معايرة التوحيد.

معايرة سعة خزان المعدات: Fill the tank in the laboratory with water, وتسجيل سعة المياه. Then set the experimental chamber to a certain humidity, قياس لفترة من الزمن, ثم قم بسكب الخزان وتسجيل سعة المياه المتبقية. Subtract the remaining water capacity from the previously recorded water capacity to get the amount of water used by the test chamber at this humidity. إذا كانت كمية المياه المستخدمة غير متوافقة مع السعة المذكورة في المواصفات, مطلوب تعديل معايرة سعة الخزان.

In order to ensure accurate and reliable test results, the constant temperature and humidity test chamber needs to be calibrated and maintained regularly. Calibration and maintenance should be carried out by experienced technicians and in accordance with the equipment’s operating manual.

Common problem solving
فضلاً عن ذلك, here are some ways that may help with common problems:

Temperature or humidity reading is not accurate: Check whether the sensor is damaged or needs to be replaced, check whether the sensor is in an appropriate position, and ensure that the sensor is the same temperature or humidity as the test box.

Unstable temperature or humidity: Check whether the equipment is disturbed by the external environment to ensure that there is not too much inside the test chamber

Debris or samples, ensure that the test box is well sealed. 3. Uneven heating or cooling of the equipment: check whether the heating or cooling components are uniform, check whether the equipment needs to be cleaned or replaced, ensure that there is not too much debris or samples inside the test box, and ensure that the test box is well sealed.

Equipment leakage or insufficient tank capacity: check whether the seal of the test box is good, check whether the tank needs to be cleaned or replaced, ensure that there is not too much debris or samples inside the test box, and replenish the water in the tank in time.

أخيراً, in order to maintain the performance and reliability of the test chamber, regular maintenance and maintenance are required. It is recommended to clean the inside of the test chamber regularly, التحقق من أداء وحالة التدفئة, تبريد, يتحكم, أجهزة الاستشعار وغيرها من المعدات, and replace or repair the faulty parts in time. في نفس الوقت, it is recommended to follow the equipment operation manual and maintenance guidance provided by the manufacturer to maintain and maintain the test box to ensure long-term stable work.
