(1) TCTemp2000: Temperature Data Logger
(1) Type E Thermocouple
(1) 9-Volt AC Power Adapter

The LNDS is an ultra-low temperature measurement system created specifically for monitoring temperature-sensitive materials that need to be preserved at cryogenic temperatures. The probe sheath can record temperatures as low as -200 °C (-328 °F) and are available in a variety of sizes.

Equipped with an LCD screen, the LNDS provides users with the ability to view the current reading, minimum, maximum and average statistics, all in real-time. This device can store 131,071 readings per channel and it’s non-volatile memory provides maximum data security even if AC and battery power are lost.

The LNDS is compatible with the latest MadgeTech 4 Software making starting, stopping, and downloading simple and easy. Graphical, tabular, and summary data is provided for analysis and can be viewed as customizable engineering units.
