TFA 45.2007 Thermo-Hygrometer 100 mm Instruction Manual

1. สินค้าหมดview

The TFA 45.2007 Thermo-Hygrometer is a precision instrument designed for accurate measurement of indoor air temperature and humidity. Featuring a classic design with a brass dial, this device utilizes a synthetic hair hygrometer for reliable humidity readings. It is manufactured in Germany, ensuring quality and durability.

This image displays the TFA 45.2007 Thermo-Hygrometer, a round device with a brass-colored rim and a white dial, mounted on a light gray wall. The dial features two scales: an outer scale for humidity (0-100%) and an inner scale for temperature (-10 to 50°C). A needle indicates the current humidity, and another needle indicates the temperature. The device is designed for indoor use, as suggested by the blurred background showing an indoor setting with a window and a chair.

2. ข้อมูลด้านความปลอดภัย

• อุปกรณ์นี้มีไว้สำหรับใช้ภายในอาคารเท่านั้น
• Avoid exposing the thermo-hygrometer to direct sunlight, extreme temperatures, or high humidity levels (above 95% RH) as this may affect accuracy and damage the device.
• ใช้งานอุปกรณ์ด้วยความระมัดระวังเพื่อป้องกันความเสียหายทางกายภาพ
• เก็บให้พ้นจากมือเด็ก

4. การตั้งค่า

4.1 การติดตั้ง

The TFA 45.2007 Thermo-Hygrometer is designed for inside mounting. Choose a suitable indoor location away from direct heat sources, air conditioning vents, or windows that receive direct sunlight, as these can affect the accuracy of readings. Use a small nail or screw to hang the device securely on a wall.

4.2 Initial Calibration (Hygrometer)

For optimal accuracy, it is recommended to calibrate the hygrometer before first use or if you suspect inaccurate readings. Follow these steps for a simple salt solution calibration:

1. Place a small cup or container with approximately 2 tablespoons of coarse table salt.
2. Add a few drops of water to the salt, just enough to make it damp, not dissolved.
3. Place the thermo-hygrometer and the salt solution inside an airtight plastic bag or container.
4. Seal the bag/container and leave it undisturbed for at least 8-12 hours (preferably overnight) at room temperature.
5. After this period, the hygrometer should read approximately 75% relative humidity. If it does not, gently adjust the small screw on the back of the device (if available) until the needle points to 75%.
6. Remove the device from the bag/container and allow it to acclimatize to the room for a few hours before taking readings.

5. คู่มือการใช้งาน

The TFA 45.2007 Thermo-Hygrometer provides instant readings of both temperature and humidity.

• การอ่านอุณหภูมิ: The inner scale, marked in degrees Celsius (°C), indicates the current ambient temperature. The needle points to the corresponding value.
• ค่าความชื้นที่วัดได้: The outer scale, marked in percentage (%), indicates the current relative humidity. The needle points to the corresponding value. An ideal indoor humidity range is typically between 40% and 60%.

Read the values directly from the dial. No power source or batteries are required for operation.

6. การบำรุงรักษา

• ทำความสะอาดอุปกรณ์เป็นประจำด้วยผ้าแห้งเนื้อนุ่ม ห้ามใช้สารทำความสะอาดที่มีฤทธิ์กัดกร่อนหรือตัวทำละลาย
• Ensure the device remains dry. Do not immerse it in water or expose it to excessive moisture.
• Periodically check the hygrometer's accuracy using the salt solution calibration method described in Section 4.2.

7 การแก้ไขปัญหา

• การอ่านค่าความชื้นที่ไม่แม่นยำ: Perform the salt solution calibration as described in Section 4.2. Ensure the device is not placed near sources of extreme temperature or humidity fluctuations.
• การอ่านอุณหภูมิที่ไม่แม่นยำ: Ensure the device is not exposed to direct sunlight, drafts, or heat sources. Allow sufficient time for the device to acclimatize to its environment.
• ความเสียหายทางกายภาพ: If the device is physically damaged (e.g., broken needle, cracked casing), it may affect its functionality. Contact customer support for assistance.
