microDL

Marathon's micro-DL is a user-programmable data logger engineered for displaying real-time temperature as well as the ability to scroll through a summary of recorded history information and high and low alarm status. State-of-the-Art electronics and water-resistant, this temperature data logger is available for use with our MDAS software or our 21CFR-DB software to comply with the FDA 21CFR Part 11 regulations.

Many configurations are available. Choose the memory size (which determines the maximum number of data points) and the temperature range to record (temperature ranges from -10C to +72C down to -200C to -100C). Then decide on the style: without a probe, with a probe, stainless steel, flat ribbon probe, teflon coated, or detachable. Single-use disposables are also available.

Tell us what you need and we will assemble a configuration to suit your needs.
