Measuring the Surface Temperature of Solids and Liquids with USB Non-Contact Temperature Sensor

The OS-MINIUSB from Omega Engineering is a tiny infrared sensor designed to measure the surface temperature of a liquid or a solid without contact. It has the ability to measure non-metal surfaces between -20 and 1000 °C, with a response time of 125 ms.

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

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

The OS-MINIUSB has a sturdy stainless steel housing that is sealed to IP65, and is engineered to handle ambient temperatures of up to 75 °C.

Compact

The sensor is only 45 mm long (plus cable gland), so it can placed into very small spaces. The USB interface is integrated into the sensor, so additional bulky interface modules are not required.

Benchtop and Laboratory

The robustness and precision of Omega’s industrial pyrometers and the plug-and-play convenience of USB makes the OS-MINIUSB an ideal fixed mount IR temperature sensor for experimentation and testing.

Education

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