•Cryogenic Temperature Logging System

2c\temp-RH temperature data logger
EDL-LN2 Cryogenic Temperature
Data Logger


The EDL-LN2 has one sensor for ambient range temperatures inside the case, and one external probe that monitors cryogenic temperatures from -200°C (-328°F) to +72°C (+162°F) for applications such as cryo-storage, freezers, refrigerators and incubators.


Certified Safe ShippingThese high-precision laboratory-grade products will operate up to 1 year without a battery change. The LCD lets you view current and stored data, prior to downloading to a computer. In conjunction with our Maxithermal software, you can document your liquid nitrogen stored products for your GxP and FDA regulated environment.
