Dry Ice and Cryogenic Data Loggers
Dry ice and cryogenic environments present some of the most challenging conditions for temperature monitoring — with dry ice storage typically running around -78°C and liquid nitrogen cryogenic freezers reaching -196°C or below. Standard data loggers are not designed for these extremes, making purpose-built ultra-low temperature loggers essential for pharmaceutical research, biological sample preservation, cell therapy storage, mRNA vaccine monitoring, and industrial cryogenic processes.
MicroDAQ carries dry ice and cryogenic data loggers from LogTag, HOBO InTemp, and Testo, all specifically designed for ultra-low temperature environments. LogTag's TRIL-8, TREL30, and UTREL30 series cover dry ice and ultra-low freezer monitoring with options for wired external sensors, wireless connectivity, and vaccine monitoring kit configurations that include glycol probes and NIST calibration certificates. HOBO InTemp's dry ice and cryogenic multi-use loggers provide Bluetooth wireless data access via smartphone — allowing data to be retrieved without opening the freezer or disturbing stored samples. Testo's 184 T4 is a single-use dry ice transport logger designed for documenting shipment conditions during pharmaceutical and biological sample distribution.
Continuous monitoring with audible and visual alarms ensures that excursions are detected immediately — critical in environments where even a brief temperature rise can compromise irreplaceable biological samples or render an entire vaccine inventory unusable. MicroDAQ also provides ISO/IEC 17025:2017 accredited calibration services for temperature measurement equipment from -70°C to 660°C. Our non-commissioned Technical Sales Representatives are available by chat, email, or phone to help you select the right logger for your specific ultra-low temperature application.
