COEUS-WIFI/4G Real-Time Temperature/Humidity Data Logger
Introduction
The COEUS series real-time temperature data loggers are ideal for real-time temperature and humidity monitoring in cold rooms, especially refrigerators and freezers. Data is uploaded periodically to Freshliance Cloud using WiFi or 4G network accordingly. Multiple users can view, analyze, and export the data remotely from our could or APP. Easy installation and accessibility are highlights of such standalone real-time data loggers. Besides, they are equipped with a built-in rechargeable lithium battery of 2600mAh, which can be available while charging, so as to ensure the long-term stability of data monitoring; and up to two external probes can be used if needed.
Features
Set and update settings remotely
These real time data loggers can be easily configured and reconfigured with the APP FreshLink, and even the computer platform, including logging interval, upload interval, alarm settings, and alarm notifications, etc.
Data transmission to the Cloud via WIFI/4G, and data review by APP and computer platform
These data loggers monitor data as configured and transfer the data to the Freshliance Cloud via WiFi or 4G network accordingly. All data are accessible via the APP and the computer platform, with data graphing, statistics, analysis, and processing.
Persistent caching during offline mode, and data re-upload after network recovery
These data loggers support 24/7 data monitoring and uploading as configured, and allow the data to be cached on the main device during offline mode and re-uploaded after network restoration, so as to ensure the data integrity.
Large LCD screen with backlight for intuitive display
An LCD screen, 85mm*52mm, is designed to intuitively display current temperature and humidity, Max./Min. temperature and humidity, date and time, battery level and communication status, etc.
Rechargeable Battery
These data loggers are designed with a built-in rechargeable lithium battery of 2600mAh, which can be available while charging, so as to ensure the long-term stability of data monitoring.
Instant, Real-time Alarms
Up to 6 alarm points can be set. When the preset thresholds are exceeded, alarm notifications will be sent via SMS, email and APP push remotely, as well as locally via flashing red indicator and the buzzer on the main device.
Multiple installation modes: Stand on end, hanging, etc.
These data loggers can be flexibly installed or placed anywhere according to the actual monitoring environment.
Multiple probe length and insulation options for the external probes
The external pluggable cable is normally 2m long and other cable lengths are customizable; cable insulation materials are also customizable, including PVC, Teflon, Silicone and flexible ultra thin cable, etc.
Flexible ultra thin cable is suitable for refrigerator door and other application environment with high sealing requirements. Besides, users can also choose sharp or blunt sensor head as required.
