Our ultra low temperature loggers are perfect solution for monitoring the temperature of -80C freezers or dry ice shipments

We offer two products for monitoring dry ice temperatures: the edl co2, for placement directly in the low temperature environment. Or the microDL80, which has a flexible probe for placing the logger outside the freezer or shipping container, with the probe inside the low temperature environment.
| Memory | Accuracy | Operating Range | Battery Life | Warranty | |
| edl co2 | 8K | 0.2˚C | -80˚C to 30˚C | 12 months | 12 months |
| microDL-80C | 8K | 0.2˚C | -80˚C to 30˚C | 12 months | 12 months |
The edl co2 is the industry standard for monitoring dry ice temperatures This product combines the functionality of the edl with the c\temp dlt's capacity to operate at extreme low temperatures (-81C). With 8k memory, 0.2C accuracy and resolution, this product is the answer for data logging low temperature freezers or dry ice shipments. For more information, download a PDF Data Sheet.
The microDL80 is our newest generation of ultra low temperature data loggers that allows real time display of the temperature while recording. This is for use in stationary applications such as low temperature freezers recording or for shipping critical biologics.
Computer Ready
