The OS-MINIUSB is a miniature infrared sensor that measures the surface temperature of a solid or liquid without contact. It can measure non-metal surfaces between -20 and 1000°C (-4 and 1832°F), with a response time of just 125 ms.

Materials including paper, thick plastics, rubber, food and organic materials, as well as painted metals and most dirty, rusty or oily surfaces, are measured accurately, safely and cleanly.

A choice of optics is available to measure small or large targets at distances ranging from a few millimeters up to tens of meters.

The OS-MINIUSB has a rugged stainless steel housing, sealed to IP65, and is built to withstand ambient temperatures of up to 75°C (167°F).

The sensor is just 45 mm (1.77") long (plus cable gland), so it can fit into very small spaces. The USB interface is built into the sensor, so there is no need for additional bulky interface modules.

Benchtop and Laboratory
With the precision and robustness of our industrial pyrometers, and the plug-and-play convenience of USB, the OS-MiniUSB is the ideal fixed mount IR temperature sensor for testing and experimentation.

The OS-MINIUSB is ideal for teaching science concepts such as emissivity, reflectivity, thermal conductivity, energy transfer, insulation and internal energy.
