Rugged & Reliable Measurement for Laboratory, Benchtop and Education Uses

The PyroMiniUSB 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°C and 1000°C, 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 millimetres up to tens of metres. It has a rugged stainless steel housing, sealed to IP65, and is built to withstand ambient temperatures of up to 75°C.

Features

• Miniature non-contact temperature sensor with USB communications
• Measures temperatures from -20°C to 1000°C
• USB cable included
• Free software for data logging and configuration
• Modbus protocol – use your own software to communicate with the sensor
• Not designed or approved for fever detection

Two models are available

• PMU21     PyroMiniUSB sensor with 2:1 optics – for large or close-up targets
• PMU201   PyroMiniUSB sensor with 20:1 optics – for small or more distant targets

Compact

The sensor is just 45 mm 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 Labratory

With the precision and robustness of our industrial pyrometers, and the plug-and-play convenience of USB, the PyroMiniUSB is the ideal benchtop temperature sensor for testing and experimentation.

Education

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

Software

See temperature readings and charts, and log data via USB in real time, with the free CalexConfig software for Windows.

CalexConfig is available to download free of charge at www.calex.co.uk/software.

CalexConfig Features

• Simple, touch-friendly software for one sensor.
• Temperature display (°C or °F)
