With technological advancements, glass thermometers are gradually being replaced by more advanced temperature measurement technologies. Below are some common alternatives and their advantages:

1. Digital Thermometers
   Digital thermometers offer high accuracy, fast response, and easy readability. Many digital thermometers also feature automatic calibration, reducing the workload of manual calibration.

2. Infrared Thermometers
   Infrared thermometers measure temperature by detecting infrared radiation emitted by objects, making them suitable for non-contact measurements. They are widely used in industrial inspection and medical fields.

3. Thermal Imaging Cameras
   Thermal imaging cameras can generate temperature distribution images of object surfaces, making them suitable for detecting hot spots, cold spots, or temperature anomalies. They play an important role in power inspection and building diagnostics.

Future Trends:

• Smart Calibration: Future temperature measurement devices may integrate smart calibration systems capable of automatically detecting and correcting errors.

• Wireless Transmission and Remote Monitoring: Temperature measurement devices may support wireless data transmission and remote monitoring, allowing users to track temperature changes in real time.

• High Precision and Multifunctionality: Temperature measurement technology will advance toward higher precision and multifunctionality to meet the needs of various fields.
