PT-104 USB PT100 DATA LOGGER ACCURACY AND RESOLUTION
Although accurate temperature sensors are widely available, it has been difficult to find a measuring device that can take advantage of them without introducing excessive errors. The PT-104 USB, however, is inherently accurate due to its novel design. Rather than relying on voltage references (which tend to be temperaturesensitive) it uses reference resistors which are extremely stable (low temperature coefficient and drift). The exact value of each resistor is stored in an EEPROM to provide the ultimate in accuracy (yearly recalibration is recommended). To achieve the 0.001°C resolution, a highly advanced ADC is used that can resolve to better than 1 part in 16 million.
TEMPERATURE
The PT-104 USB measures temperature using platinum resistance thermometers (PRTs). Both common industry standards (PT100 and PT1000) are supported. The unit is compatible with 2, 3 and 4 wire sensors (4 wire PT100 sensors are recommended for accurate measurements). A wide range of PT100 sensors are available for use with the PT-104.

ADC-11The ADC-11 has been discontinued; however, due to its popularity, the PicoLog 1000 Series logger includes a USB ADC-11 compatibility mode which enables it to act as a direct replacement for the USB ADC-11.
