No Maintenance

There are no pens or paper charts that need to be changed. Temperature is stored in the RAM memory of the ThermaViewer® which draws the temperature or temperature/RH chart on its large LCD display. A 1.5 year chart of temperature history can be viewed on the screen. After the memory is full the new temperature writes over the old temperatures so you always have the last 1.5 years of temperature history in memory and on the display. All temperature history can be downloaded to a computer to print a copy of the chart.
No more charts or pens to change -
ever.

Stores years of temperature history
A continuous chart is always visible on the large LCD display. Over 1.5 years of temperature history is saved and can be scrolled through if temperature is sampled every ten minutes. In fact you can zoom out of the display to see all of the stored samples on the screen at one time. Trends are very easy to spot. (specs)
Multiple displays
In addition to seeing the chart for each sensor on the display you can use a trace mode to scroll through each individual reading. You can zoom into the data to examine each individual reading, showing the day and time it was taken. Scroll through, zoom in, trace readings, print a paper record, archive to a PC. These features make it easy to zero into a temperature high point and see when it occurred, how long it lasted and whether it was a spike or a slow ramp up in temperature.
Two remote sensors
The monitor comes with two sensors, each on a twenty-foot wire. The sensor wire can be extended so that the two sensors can be placed 100s of feet from the display unit. The sensors transmit data digitally so that there is no loss of data due to transmission distances.
Triggers an alarm or dialer
The monitor has an on-board alarm and a relay which can trigger an external alarm or dialer. High and low set points are set by the user. The on-board relay closes if user-set temperature set-points are exceeded and can be used to trigger an auto dialer or local alarm. An optional four number auto dialer and local alarm are available for the ThermaViewer®
