Marathon Products introduces the microDL -200°C LCD display data logger. This device helps monitor and validate critical low-temperature products, such as biologics, during storage and transfer. In conjunction with optional 21CFR compliant software, the microDL -200°C will document liquid nitrogen stored products for GxP and FDA regulated environments. With an operating range of 72°C to -200°C, themicroDL -200°C will operate up to three years without a battery charge. The one-touch display shows current temperature, elapsed time in days since last check, mean kinetic temperature, high and low temperatures, alarm time over high or under low temperatures, and alarm conditions.
