Dear Rick,
|
|
Our customers were tired of the old-fashioned
mechanical chart recorders. They did not like having
to change the paper charts and pens all the time. It
took many man hours each year and the supplies were an
added expense.
Some of them tried data loggers, which did get rid of
the charts and pens, but then they could not see the
data. The collected data had to be downloaded to a
computer before it could be seen.
What they really wanted was a combination of the two.
They wanted a data logger that displays a chart like a
chart recorder. Or a chart recorder without the paper
and pens and ongoing maintenance.
So we made one for them.

We have the
answer!

The traditional
 chart
recorder samples temperature on a periodic basis and
plots them on a round piece of paper with a small ink
pen. The result is a graph or chart showing the
temperature history for the last day, week or month.
Chart recorders use one or two sensors to collect
data. A temperature/humidity chart recorder, for
example uses both a temperature sensor and a humidity
sensor, drawing a chart with two colored pens.
The ThermaViewer does not use paper charts or
 pens
at all. It draws the chart on it's LCD display. And
the chart can cover months and even years of time.
The
ThermaViewer™
really is a combination data logger and chart
recorder, combining the visual aspect of a chart
recorder with the storage capacity and flexibility
of a data logger.
Like a data logger it continually samples and
stores data, but unlike a data logger it
doesn't need a computer to setup or to view the
data.
Like a chart recorder it samples and displays
data, but unlike a chart recorder it stores
months of data, doesn't require charts, pens or a
staff member to change the chart.
Now you decide. Go to www.e2di.com and see for
yourself. Then tell us your opinion. Is this what
you've been waiting for?
The ThermaViewer,
the best way to monitor and document temperature.
