What's New?
Steve Kuwahara has become an advisor to  
Marathon Products and a consultant to their
customers. Marathon Products manufactures
temperature recording data loggers that are highly
versatile and small enough to be used in many
locations. Their microdl device has a wide dynamic
range that makes it suitable for use at freezer
temperatures and at room temperature. Ultra low
temperature devices are also available. The device
may be used to monitor shipments and also to
monitor the temperature distribution in incubators
and warehouses.
The microDL can also come with a remote (RfD)
monitoring feature that reduces the leg work in
monitoring large spaces. Steve finds these devices
ideal for Cold Chain Management and Environmental
Monitoring of facilities.
Because of their size, they can also be used to
monitor temperatures inside of various
configurations of loads in incubators and
environmental chambers, without the need for
multiple probes an extensive wiring.

Contact Marathon Products for more information on
their device and contact us for consulting services
on performing shipping and other validations using
these devices.
