OM-21 Series are in the end of its life cycle. As a possible substitute/upgrade, please check out Newest Released One Time Use PDF Logger OM-21A Series for more advanced features with better price.
The OM-21 data logger is for use in cold chain
applications to monitor the transportation of
pharmaceuticals, food and other temperature sensitive
products. The data logger is completely user-programmable
including language selection, sampling
interval, start delay, alarm delay, temperature units,
alarm range, alarm type, password and user name.
The unit’s compact, lightweight, waterproof and flat
design allows it to fit inside any package. No special
software or driver is required for set-up or download
of data. On completion of data logging a PDF report
is automatically generated containing data summary,
graph and tabular results. The data logger appears as a
mass storage device when connected to the PC. User
manual, set-up utility and PDF report are all stored in
the data logger.
