The JDL Little Logger measures and records up to 2048 time-stamped temperature recordings between -10 and +85C.
The JDL Little Logger measures and records up to 2048 time-stamped temperature recordings between -10 and +85C.
The logger comes with Windows software on CD, interface cable and two soft-mounted plastic fobs for identification.
User features such as graphing of the data collected, the saving of files, zooming of pertinent data and the setting of alarm thresholds are provided through the software.
Data can also be easily transported into other spreadsheets and software packages.
The Little Logger has 8bit resolution, an accuracy of +/-0.5C from 0 to 70C and has sampling rates that are user selectable from 1 to 255min.
Start delay is up to 255min and sampling methods are selectable, continuous (first-in/first-out) or stop when full.
Alarm is user selectable.
Housed in a stainless steel container only 16mm in diameter, this micro-sized data logger will record for up to 10 years on its internal 3V lithium power source.
The JDL Little Logger is a useful tool for applications where a profile of time-based temperature variations are required in ambient air spaces.
It is also very applicable for use in process monitoring of temperature critical machinery.
This is important when the operating temperature of components such as hydraulic fluids, housing, and when ambient air space is exceeded, thus degrading machinery efficiency and leading to part failure.
Likewise with food processing, it is critical that temperatures in food remain constant with product requirements, as it passes from "farm to fork".
Spot-checking temperatures may not reveal a temperature breach but, with the Little Logger, it will provide a profile of time-based temperature variations within any one of the critical components during the passage of time.
With the Little logger software, users can also be provided with such features as graphing of all the data collected, the saving of files, zooming of pertinent data and the noting of alarm thresholds.
