Two Dimensional Instruments, LLC
2DI was founded in 1999 to design and build electronic instruments to provide critical information to business and industry.
The ThermaViewer 1, our first product, was introduced in 2004. This unique instrument uses external wired or wireless sensors to sample, store and display temperature or temperature/humidity on a large LCD display. Current and historical conditions are always visible on the large LCD.
Since 2004 many improvements have been introduced.
ThermaViewer data is always visible on the large display and can be downloaded to a computer for long term storage or printing a paper record.

The ThermaViewer is used in research, industry and business to protect and comply with regulatory requirements for monitoring temperature and/or humidity. They are used in blood banks, doctor offices, pharmaceutical companies, warehouses, laboratories, manufacturing facilities, museums, etc...
The ThermaViewer initially used a digital sensor to sample temperature, which worked great for refrigerators and freezers, but wasn't accurate enough for some more-demanding-applications. More accurate sensors for accuracies of ±0.3C°, ±0.2C°, and even ±0.1C°. Any type of thermocouple sensor can also be used with the ThermaViewer display unit.
Our customers are laboratories, food manufacturing companies, warehouses, hospitals, pharmaceuticals, nursing homes, hospitals, trucking fleets and anyone else who must monitor and document temperature or temperature/RH. They 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, supplied by two major universities with outstanding engineering schools.
