UNRESTRICTED
The OS-Mini and OS-Mini22 are a range of miniature, non-contact infrared temperature sensors with
separate electronics modules.
All OS-Mini models have an adjustable emissivity setting and are capable of measuring a wide variety of
target materials, including food, paper, textiles, plastics, leather, tobacco, pharmaceuticals, chemicals,
rubber, coal and asphalt.
All OS-Mini22 models use a short measurement wavelength for greater accuracy, and improved tolerance
of optical obstructions or errors in emissivity setting, than long-wavelength sensors.
The optional touch screen interface for OS-Mini and OS-Mini22 provides temperature indication, alarms,
sensor configuration and data logging to MicroSD Card. For OS-Mini models specifically, an optional high-
temperature sensing head may be used in ambient temperatures of up to 180°C without cooling. The low-
noise cable on high ambient temperature models is resistant to interference from movement, so it is ideal
for mounting on moving objects such as robot arms.
Different choices of optics are available to measure small or large targets at short or long distances, and,
there is a choice of 4-20 mA, RS485 Modbus and alarm relay outputs.
