COEUS-UEX Temperature Humidity Data Logger

COEUS-UEX Temperature Humidity Data Logger

Large LCD screen for intuitive display

Audible and visual alarms, up to 6 programmable alarms

Up to 9 event markers

User configurable parameters, battery rechargeable

Optional external probe


COEUS-UEX is a multi-use, rechargeable, and configurable  temperature and humidity data logger with a large temperature humidity display. The built-in PDF / CSV file generation function enables this Thermometer Hygrometer to directly generate irreversible data reports in PDF / CSV format by connecting the logger with the PC, with no software required. Temperature Sensor Data Logger is a versatile wide-range Temperature Humidity Controller with a high-resolution temperature range of -30℃~+55℃,  for up to 35,000 readings with real-time temperature data and time. This Temperature and Humidity Monitor can be used in fields like the medical industry, food industry, production workshop, agricultural research, biological laboratory, etc.


Intuitive large LCD screen

Real-time viewing of current temperature and humidity, Max/Min temperature and humidity, date and time, and battery level.

High accuracy and large data capacity

External probe with wire of 2 meters can measure temperature from -30℃ to +55℃ with high accuracy. Up to 35,000 memory capacity.

Audible and visual alarm

The Temperature Humidity Meter can be set in 3 groups of high and low temperature alarms. When the temperature exceeds the preset value, the beep alarm will be active with a red light flash to alert.

Switchable built-in and external sensors

You can select built-in or external sensor measurement at the first use as needed, you can also switch the built-in and external sensor during use by short pressing the button.

Battery rechargeable with long working days

Adopting a rechargeable lithium battery, work up to 500 days.

Temporary report history available

The temporary report will be automatically generated when the ultra-low temperature sensor is connected to the USB port of the computer.

COEUS-UEX Temperature data logger with large temperature humidity display can be used for the preservation of drugs, blood serum and chemical reagents in pharmaceuticals industry and biochemical laboratories. These biological products need to be stored in a constant temperature and humidity environment. The temperature and humidity data during storage can be used as the factual basis for medical malpractice identification. 

Production plants and warehouses in the food industry need Temperature Sensor temperature data loggers to record temperature and humidity to ensure the quality of production at all stages.

Agricultural research has certain requirements for temperature and humidity in the environment. So humidity and temperature controllers are needed to record temperature for a long time.

COEUS-UEX Ultra Low Data Logger Temperature Sensor is a room temperature humidity controller. This Thermometer Hygrometer can be used in museums and archives, which also require precious items to be kept in a certain temperature and humidity environment. So these Temperature Sensors are also needed to record real-time temperature to ensure their integrity.


Freshliance Tools

Freshliance Tools is a desktop software for users to use Freshliance USB data loggers. It consists of three pages: Summary, Graph and History. On the Summary page, the software will first automatically identify ID, model, recording type, sensor type, battery level, status and other information of the device plugged in. And then users can configure the data logger as needed, including start mode, start delay, time zone, time format, logging interval, report format, PDF/software password, high and low alarm, etc. During or after data recording, user can also check statistical information of the device after plugging it in. Besides, the graph page provides a simple X–Y plot of time versus temperature/humidity which can be save as PNG format file, a list and a summary of all data recorded, as well as an option to export the report in PDF, CSV, TXT format; and the history page provides a list of all the devices whose report was read by this software.

The software is designed for Fresh Tag 10T/TH, Thermis Log 10T/TH, Tagplus-T/TH, Atlas Log-30/60/90/200/IUT, Rugged data logger, Keeper 1/IUT, COEUS-UEX.
