Real-time Temperature Sensor for Chest Freezer Monitoring

Chest freezers and upright freezers are essential for catering companies, grocery stores, and biomedical labs. These machines keep food and delicate samples at a steady, safe temperature, which is key to keeping products intact and operations running smoothly. When the power goes out or equipment breaks down unexpectedly, users can lose valuable stock and samples in a very short time. That's why real-time temperature monitoring is no longer optional—it’s a must for protecting assets. Freshliance’s real-time temperature sensors are made just for freezers, offering accurate, automatic remote monitoring to prevent expensive losses before they happen.

Real-time Monitoring

The COEUS real-time temperature sensor unit sends live temperature data to the cloud at once, using either WiFi or 4G connectivity. Users can check readings anytime, from anywhere, through the mobile app or cloud platform, and export complete data records whenever needed.

Optional External Probes

This real-time temperature sensor can connect up to two external probes, with customizable options for Temp/RH, cable length and material to match different working conditions. We also supply ultra-thin cables, so the freezer door can close fully and maintain its seal, without disrupting monitoring accuracy.

Remote Alerts

When temperature goes beyond the set safe range—such as rising above -15°C—users will get instant alerts via SMS, email or app push. The real-time temperature alarm logger also has a sound and light alarm on board, so staff on site can notice and fix the problem quickly.

Continuous Monitor

Built with a 2600mAh rechargeable lithium battery, the COEUS-4G/WiFi real-time temperature sensor keeps running even during power cuts. Ensures no interruptions to tracking and full, complete data records without missing gaps.

API Integration

For customers who use their own software or management platforms, the COEUS-4G/WiFi temperature and humidity logger supports API services. This makes data integration easy, allowing teams to view and record all related information directly through their existing systems.

The COEUS-4G/WiFi temperature and humidity logger works well for cold chain warehouses, labs and industrial refrigeration monitoring. We also support USB data loggers and IoT solutions for diverse needs. If you have specific requirements or need more product details, we are ready to help you.
