The PT-104 is a high-resolution, four-channel temperature data acquisition module for use with Pt100 and Pt1000 RTD sensors. The CE-compliant unit measures temperature, resistance, and voltage, and it does not require a power supply. It uses either an RS-232 or a USB interface (USB interface via an included RS-232-to-USB interface converter), and Windows software is included for basic data acquisition and display. It is suitable for chemical, water, and food industry applications, among others.
