中文Laboratory refrigerators and freezers are built to much higher standards than household models. They offer greater precision, safety, and temperature stability, all to preserve the quality and safety of sensitive samples like biological materials, chemical reagents, and vaccines. For this reason, these cooling units need consistent, reliable temperature monitoring to maintain stability and uniformity. Freshliance COEUS-WiFi and COEUS Mini-WiFi real-time temperature recorders bring clear practical benefits to lab cold storage monitoring.
Common types of laboratory cooling equipment include the following:
| Model | Temperature Range | Usage |
|---|---|---|
| Freezer | -20°C ~ -40°C | Cryopreservation of research samples, drugs, and bacterial strains |
| ULT Freezer | -80°C | Long-term preservation of cell lines, tissue samples, microarray experiments, etc. |
| Fridge | 2°C ~ 8°C | Storage of biological reagents, buffers, culture media, and chemicals |
| Walk-in Fridge | 2°C ~ 8°C | Large-scale storage or low-temperature experimental operations |
| Liquid Nitrogen Tank | -196°C | Long-term deep cryopreservation of samples |
Most are also fitted with automatic high and low temperature alarms, such as temperature and humidity recorders, to help prevent sample damage. The COEUS-WiFi real-time temperature recorder uses a built-in temperature and humidity probe to reliably track conditions from -30°C to +60°C. The WiFi temperature sensor also supports two optional external probes, so users can monitor two separate temperature zones at the same time and compare data more easily. This makes it especially useful for multi‑zone refrigerators, where separate compartments help avoid cross‑contamination. The laboratory wireless temperature recorder can be installed with magnets or mounted on a wall, so users can attach it directly to the outside of a fridge for quick readings or fix it in place for long-term monitoring. Its high-capacity rechargeable battery supports repeated use and helps lower long-term monitoring costs.
The COEUS Mini-WiFi real-time temperature recorder is smaller and designed for simpler, single-zone fridges and freezers, with one optional external probe. With the right probe attached, both models can accurately measure temperatures from -90°C up to +200°C. Users can access all device data through a free cloud platform and mobile app. They can view everything on a central dashboard in the lab, check readings remotely, share data, or export reports at any time. If temperatures move outside safe ranges, the system sends real-time alerts by email, SMS, or app notification, so staff can respond quickly. For labs that need to connect monitoring to their internal systems, API integration is also available upon request.
