RFID tags
also function as data loggers
By Pamela Riemenschneider
Initial start-up costs to use the
Therm-AssureRF begin at about $1,000
for the scanner/reader (above), plus
$500 for contracted support.
Evidencia LLP supplies a free reader
if 250 tags are purchased, says Alex
Salomon, general partner.

(July 30) Evidencia LLP wants you to forget what
you know about radio frequency identification
when you’re talking about its ThermAssureRF tag.
“We took a totally different approach to making
a temperature logger,” said Alex Salomon,
general partner of the Memphis, Tenn.-based
company. “We’re not aiming to be an RFID
company. We’re offering a true, working,
available-today wireless recorder that will
enable people to monitor product at a short
distance as often as they want.”
The ThermAssureRF, which was introduced for
produce and perishables at the Fruit Logistica
show in February, was first pilot-tested in
2005, after which it underwent commercial trials
in 2006 by Chiquita Chile, Pandol Bros. and
Chilean avocado shipper Rio Blanco Ltda.
The tag is unique, not only because it is read
using radio frequency technology, but also
because it can be placed inside a box and be
read through cartons and polystyrene from up to
6 inches away using a hand-held device, Salomon
said. Tags are encased in plastic and are
waterproof. With an optional probe thermometer,
pulp temperature also can be recorded.
“You can get to the heart of the pallet,”
Salomon said. “Customers finally have a way,
without destroying the pallet or retrieving the
temp recorder, to check on precooling to make
sure they’re getting what they pay for. You can
stick it in the box and have the true
temperature of the box instead of just relying
on the air temperature.”
Evidencia thought the tags would be used
primarily for truck monitoring, Salomon said,
but customers are finding many more uses for
them.
“That is the surprising part,” he said. “We are
seeing them being used as early as in field and
orchard monitoring, for cherries, for instance,
or for field picking activities where
temperature is key, for strawberries, then on to
precooling, cooling and finally trucking.”
Tags can be programmed to e-mail a client every
time they are read or whenever a temperature
reading finds product has been out of range.
Salomon said this can be particularly useful for
the import/export market.
If a container is being loaded on a ship at the
wrong temperature, an importer is able to know
ahead of time and have a plan in place for when
the load arrives, Salomon said.
“An importer can move that product right away
and not store them in their distribution
center,” he said. “That element of proaction
represents a lot of savings. They can pull the
container first and see what the damage is and
move them right away.”
