Why: Our passion is to make it easy for non-engineers to monitor, log, chart and alarm critical storage conditions.
How: We use the latest technology to simplify the user interface of sophisticated equipment monitoring temperature, humidity and pressure.
What: We design and build electronic instruments that monitor, log, chart and alarm storage and ambient variables that are easy to install and use.
Two Dimensional Instruments, LLC (2di) was founded by the current president and lead engineer, Rick Kaestner in 1999. Their first product was a freezer alarm with an intuitive user interface. The freezer alarm module used remote temperature sensors to monitor freezers and refrigerators. Additional sensors for relative humidity and pressure sensors were added as options soon after. Data logging was always a part of the design since a temperature history is so much more informative than a spot check. There were data loggers but they were designed for engineers and were far too complicated non-engineers. They also lacked the ability to provide real time information, send alarms, display graphical charts, and accommodate multiple sensor types.
The ThermaViewer 1, our first product, was introduced in 2004. This unique instrument could be setup and operating in just a few minutes. It used remote wired or wireless sensors to sample, store and display temperature and humidity history on a large LCD display. All samples were stored in memory and displayed as a paperless chart. The current and historical conditions were always visible on the large screen.
In 2013 we introduced the TV2 with Easy-Touch, which could also be setup and operating in a few minutes. It duplicated the functions of the ThermaViewer 1, and added a color touch-display, and the ability to use more and other types of sensors. The color display enabled a two stage alarm. If any value moved outside the safe zone it turned red. New differential pressure sensors were developed which made the TV2 ideal for monitoring, logging, alarming and charting environmental variables in pressurized rooms of all sorts: cleanrooms; positive pressure rooms; negative pressure rooms; nuclear medicine areas; pharmaceutical assembly rooms; etc…
