USB/Ethernet logger records four channels of data

It is compatible with standard, low-cost PT100 and PT1000 platinum resistance thermometers (PRTs), including two-, three- and four-wire types.

By using calibrated reference resistors instead of semiconductor voltage references in its measuring circuits, the PT-104 is less susceptible to temperature drift and delivers high stability and accuracy at a low cost.

The PT-104's temperature measuring range is -200 to 800C, with an accuracy of 0.01deg and a resolution of 0.001deg.

Resistance ranges are 0 to 375ohms and 10 kilohms with an accuracy of 1 microhm, and voltage ranges are 0 to 115mV and 2.5V with an accuracy of 156 microvolts.

Conversion resolution in all modes is 24 bits.

The PT-104 is supplied with Pico Technology's Picolog data logging software, which runs on any Windows PC (Windows XP or later).

Picolog can collect data from any number of PT-104 loggers at programmable intervals from 720ms per channel up to minutes, hours or days.

Results can be simultaneously displayed in a monitor window with optional limit alarms, and as a live graph and a table.

Data can be exported in a standard text format compatible with other spreadsheet and analysis programs.

The dual USB/Ethernet interface allows the logger to be used in a variety of situations, such as USB-only, USB-powered with Ethernet interface and Ethernet with Power-over-Ethernet (PoE).

Using the Ethernet interface, the PT-104 can be located anywhere on a LAN or on the internet.
