Product Description
Product Overview
The JS8746 Harsh Environment Temperature Sensor is engineered for critical temperature monitoring in demanding conditions, particularly for the transportation of goods by land, sea, and air. It ensures the integrity of temperature-sensitive merchandise, such as medical products, by maintaining strict temperature limits, thereby preventing deterioration and avoiding costly product write-offs. Designed to meet statutory requirements and performance expectations, this sensor is ideal for HVAC control systems in the container-ship market, offering robust protection against water ingress and degradation from harsh marine environments. Its advanced materials and build standards ensure reliable performance even when exposed to corrosive elements like salt solutions, ozone, UV radiation, and cleaning detergents.
