English Introduction
The WRE-640 is a dual-element platinum resistance thermometer specifically designed for indoor use. It features high-quality platinum as the temperature-sensing element, offering excellent measurement accuracy and stability. Within the wide temperature range of -200℃ to +850℃, it can provide precise and reliable temperature data, making it suitable for various indoor applications such as environmental monitoring and equipment temperature control.
The dual-element structure allows for two independent temperature signals, which can be used for redundancy to ensure system reliability or for different measurement purposes, enhancing measurement efficiency. The compact design of the WRE-640 makes it easy to install in space-limited indoor locations, such as ventilation ducts and small equipment interiors. The housing is specially treated to provide good protection against common indoor environmental factors like dust and humidity, extending the product s lifespan and reducing maintenance costs.
We are committed to providing high-quality products and services. With its outstanding performance and practical design, the WRE-640 is an ideal choice for indoor temperature measurement.
