Product Overview
The JS8746 Harsh Environment Temperature Sensor is engineered for critical temperature monitoring in demanding applications, particularly within the transportation sector (land, sea, and air). Designed to ensure the integrity of goods during transit, this sensor is vital for maintaining temperature-controlled environments, especially for sensitive items like medical products where strict temperature adherence is a statutory requirement. The sensor is specifically developed to address the challenges of the marine environment, offering robust protection against corrosive elements such as salt solutions, ozone, UV radiation, and cleaning detergents. Its advanced design and materials ensure reliable performance and compliance with stringent measurement and performance expectations for HVAC control systems in container shipping.
