MadgeTech’s LNDS, Liquid Nitrogen Data Logging System, is an ultra-low temperature measurement
system created specically for the monitoring of temperature sensitive substances that need to be
preserved at cryogenic temperatures.
The LNDS can be mounted to the top or outer of a cryo-shipper or freezer, and the probe sheath can be
inserted into the tank. The user can then directly view the internal temperature through the LCD on the
logger. Also, a variety of probe sizes are available.
MadgeTech’s LNDS is easily user programmable with pre selected sample rates from between 2 seconds
to 24 hours, and it features a programmable start time and date, up to six months in advance.
The 8-button membrane keypad and large LCD provides the user with the ability to view the current
reading, minimum, maximum, and average statistics, in real-time. The non-volatile memory will retain
data even if AC and battery power are lost. Also, the 9-volt battery it runs on is both user-replaceable
and cost eective.
The Liquid Nitrogen Monitoring System includes the TCTemp2000 data logger with a calibration certication, thermocouple probe, and 9 volt AC wall mounted power adaptor.
