The TV2 is a highly engineered monitor/alarm/logger with a simple user interface. It uses
remote wire or wireless sensors to collect temperature, humidity and/or pressure data. The
Easy-Touch™display shows current conditions as well as days, weeks, months and even years of
logged data. It complies with all federal regulations.
It displays current, maximum /minimum conditions and digital charts for four remote sensors.
It logs and charts all monitored conditions which it stores in non-volatile memory for
protection. All stored data is encrypted to comply with 21 CFR 11, and can be copied to a
computer for archiving or printing through a USB cable. All captured data can be viewed in
graphic form or exported to an Excel file.
The TV2 stores up to 80,000 data points for each sensor, which means that it will store over
1.5 year of temperature history if you are sampling temperature once every 10 minutes. If
you are logging temperature and humidity it stores nine months of history for each of the
four sensors. Although the TV2 can store and display temperature from absolute zero to
thousands of degrees, the actual temperatures collected depends on the type of sensors being
used (see below).
In addition to showing the current conditions the TV2 can display the logged data for each
sensor. Touching one of the displayed values on the QuickCheck display causes the logged
data to be displayed as an easy-to-read chart. The chart can be scrolled backwards and
forward. It can also be zoomed into or out of to show more or less data.
