2di 2DI was founded in 1999 to design and build electronic instruments to monitor,document, and alarm for critical conditions.

We manufacture the ThermaViewer and TV2 which show a temperature history chart as well as the current conditions on its LCD display. The ThermaViewer is used in research, industry and business to protect and comply with regulatory requirements. It is used in blood banks, doctor offices, pharmaceutical companies, warehouses, laboratories, manufacturing facilities and museums. The first ThermaViewers used digital sensors to sample temperature, which worked great for refrigerators and freezers, but wasn't accurate enough for some more-demanding-applications. More accurate sensors with accuracies of ±0.3C°, ±0.2C°, and even ±0.1C° were added in 2008 and now most types of thermocouples can also be used with the ThermaViewer display unit. In 2010 we added wireless temperature and humidity sensors for the ThermaViewers. The best thing about our ThermaViewers is that the user does not have to go to school to use it. Our customers are often non-engineers who really do not want to become engineers. We believe that for instruments to be useful they must be easy to setup and use. Our customers love the ThermaViewer because it is self-contained, stores years of temperature history, require no maintenance and cost less than the alternatives. We are located near Louisville, KY, the 16th largest city in the US, where we have access to the latest in manufacturing facilities and some of the best engineering talent available anywhere in the world. The two major universities located nearby have outstanding schools of engineering. Louisville is also the major shipping hub for UPS, so we can easily and quickly ship to anywhere in the world.

We recently added a 'Last Reviewed' button to the TV2 monitor. When an employee touches the button a data and time stamp is placed in the logged data. The reviewed times also download to the alarm logs on the PC interface.

Monitor & document temperature with a Data Viewer

The ThermaViewer is a stand-alone data logger and paperless chart recorder in one instrument. You always know, not only what the temperature is but what it has been. You do not have to download the data to view the temperature history, like you do with other data loggers. The current temperature and temperature history chart are always visible on the large LCD display to remind every one in your company how important the correct temperature is.

2di Data Viewers use 120 volt wall power with a 40 hour backup battery for power failures. It continues to operate normally during brown-outs or black-outs so that a continuous record of the temperature in maintained whether it is getting power from your wall outlet or the backup battery. Even the alarm and external relay operate properly while in battery mode.

The displayed chart, which is similar to the chart created by conventional chart recorders, can be scrolled through or zoomed into and out of, so from 3 hours up to one year or more of temperature history can be seen on the screen at one time. Trends can be spotted and individual data points examined.

Constructed to last for years it can be safely installed in almost any environment. It has no moving parts, requires no paper, pens or ongoing maintenance. Our Data Viewers do not need a computer to setup or operate as conventional data loggers do.
