The OM-CP-RFTC4000A is a miniature, wireless, battery powered, stand-alone, thermocouple based temperature transmitter. This all-in-one compact, portable, easy to use device will measure and transmit temperature measurements. When enabled, the wireless transmitter will transmit readings back to the host computer where the data can be analyzed in real time. These readings are also logged to the device’s memory for added data security. The convenient slide switch alows the transmitter to be turned On or Off without affecting the operation of the device. Data is received at the PC using the OM-CP-RFC101A receiver that attaches directly to the serial port. All received data is time and date stamped and stored directly in your PC. Its small size allows it to fit almost anywhere.

The OM-CP-RFTC4000A is a major leap forward in both size and performance. Numerous devices may transmit data to the same receiving station.The Windows software converts your PC into a real time strip chart recorder. Data can be printed in graphical or tabular format and can also be exported to a text or Microsoft Excel file.
