The OM-CP-RFRTDTEMP101A is a battery powered precision temperature recorder and wireless transmitter. This is an all-in-one compact, portable, easy to use device that will measure and record up to 5,461 measurements. The OM-CP-RFRTDTEMP101A combines the features from the standard product line and adds the convenience of a wireless transmitter. 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 allows the transmitter to be turned on or off without affecting the operation of the device.

The device can be started, stopped and configured directly from your computer. Its small size allows it to fit almost anywhere. In addition to the wireless communications, the OM-CP-RFRTDTEMP101A makes data retrieval quick and easy. Simply plug the device into an available COM port and our user-friendly software will handle the rest.
