Record and Log Ultra-Low Temperatures in Shipments, Refrigerators or Freezers
The true recording thermometer which displays real time information as well as data logging temperature.
Our microDL-80C digital display technologies now operate at ultra-low temperatures of -80C (-112F). The microDL-80C with the external thermistor probe can now help you verify that internal temperatures of your dry ice packages meet specifications prior to acceptance of your shipment. Simply push the start button to view critical temperature information upon arrivals.
microDL-80C
This product can be programmed in Celsius or Fahrenheit.
Pressing the Start button will display the following visual information: whether or not the logger is Recording, the Current Temperature, Elapsed Time in Days, MKT (Mean Kinetic Temperature), High Temperature, Low Temperature, Alarm Time Over High Temperature, Alarm Time Below Low Temperature and Alarm Conditions.
After reading the display you can download the recording to your PC and plot the data, or wait to archive your temperature data at a later time. The compact, coin-sized mdl-80 is the industry standard for monitoring dry ice temperatures This product combines the functionality of the microDL with the ability to operate at extreme low temperatures (-81C). With optional memory sizes of 8k, 32k and 64k, 0.2C accuracy and resolution, and a one meter long flexible ribbon probe this product is the answer for data logging ultra low temperature freezers or dry ice shipments.
Flexible
The internal software of the data loggers provide features for controlling and querying its status. These functions include Delay to Start, Stop, Elapsed Time as well as customizable sampling time intervals. Also available: User Descriptions for initialization and for downloading the data; High and Low Alarm values, Mean Kinetic Temperature, Recording Status, Real Time measurement display as well as much more.
Visual Alarms
All our data loggers have the ability to program alarm limits. Should the temperature reach levels outside these limits, the digital display will show a notice until reset by the user.
Computer Ready
Our proprietary microDL Reader is needed to download temperature information to a computer. Marathon's easy-to-use MDAS-Pro software is available for PCs running Microsoft Windows 2000, XP and Vista.
