Pico PP682 PT-104 USB Datalogger

The PT-104 is a four-channel temperature measuring data logger. It offers the ultimate in resolution (0.001 °C) and accuracy (0.015 °C). Along with temperature it can also be used to measure resistance. Although accurate temperature sensors are widely available, it has been difficult to take advantage of them due to errors caused by the measuring device. Your PT-104, however, is inherently accurate due to its innovative design.

Rather than relying on voltage references, which tend to be temperature-sensitive, it uses reference resistors, which are extremely stable with low-temperature coefficient and drift. The exact value of each resistor is stored in an EEPROM to provide the ultimate in accuracy (yearly re-calibration is recommended). A high-performance 24-bit ADC is used to achieve the 0.001 °C resolution.
