Product Description

Product Description

COEUS series data loggers are the real-time temperature data loggers with WiFi or 4G connectivity. COEUS-WiFi can be placed anywhere within range of a WiFi network and be left to monitor, and then use the existing WiFi router network with no additional gateways or repeaters to transfer all recorded data to the Freshliance Cloud, while COEUS-4G is the upgraded one with 4G network, directly transferring the data to the cloud via 4G connectivity. All data are wirelessly accessible worldwide via the mobile APP and computer platform, with alarm notifications by SMS, emails and APP Push, etc. They are suitable for the environmental monitoring of cold rooms, freezers, walk-in coolers, server rooms, food storage, cigar humidors and labs, etc.

Features

et 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
