English Introduction
The WREK-440 dual-element platinum resistance thermometer is a high-precision temperature measurement component specifically designed for indoor environments. It is made of high-quality platinum material, which ensures good stability and repeatability. Within the wide temperature range of -200℃ to 850℃, it can accurately and stably output resistance value signals that are linearly related to temperature. It meets the temperature monitoring needs of various indoor locations, such as laboratories, temperature-controlled warehouses, and clean rooms, providing a reliable basis for environmental control and temperature management.
The thermometer features a compact structure with a dual-element design, which provides two independent measurement signals. This redundancy enhances the reliability and safety of the measurement. In terms of installation, it is equipped with interfaces that are compatible with multiple installation methods. Whether it is mounted on walls, pipes, or other structures, it can be easily and securely installed without the need for complex tools or techniques.
In terms of performance, it responds quickly to temperature changes, allowing it to capture even the slightest fluctuations in indoor temperature and ensure the real-time nature of the measurement data. Over long-term use, it has strong resistance to interference and is not significantly affected by common indoor environmental factors such as electromagnetic fields and dust, ensuring the accuracy of the measurement remains stable. Additionally, it has good corrosion resistance, allowing it to adapt to different indoor environmental conditions, such as varying humidity levels and chemical concentrations. It has a long service life and low maintenance costs, making it an ideal choice for indoor temperature measurement.
