1. The thermometer should be used in an environment where the ambient air temperature is -10~+55 ℃ and the relative humidity is not greater than 80%.

2. The thermometer should be installed vertically on a mounting plate without vibration to reduce additional errors caused by vibration.

3. The temperature pack must be fully immersed in the measured medium (and inserted as deeply as possible to reduce errors caused by the heat dissipation of the temperature pack installation bolts), and the measured medium needs to flow frequently.

4. During installation, the capillary tube should be straightened and fixed with a rolling head at intervals of no more than 300 millimeters. The bending radius of the capillary tube should not be less than 50 millimeters.

5. The working temperature of the thermometer should be between 1/2 and 3/4 of the measurement range.

6. In any case (regardless of handling, installation, or operation, etc.), the thermometer should avoid vibration, collision, and impact.

7. When measuring liquids, gases, and vapors that have a corrosive effect on copper and copper alloys, please indicate this when placing an order.
