The OS-MINIUSB is a simple, compact infrared temperature sensor with USB communications. It
measures the surface temperature of a variety of materials without contact.
The included software is intuitive and easy to use, and the open Modbus protocol allows users to
connect directly to the sensor using software of their own design.
The sensor’s rugged construction makes it ideal for benchtop, laboratory and education
applications.
