  • 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

The Calex PyroMiniUSB is a simple, compact infrared temperature sensor with USB communications. It can measure the surface temperature of a solid or liquid without contact. It can measure nonmetal 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.

The sensor’s rugged construction makes it ideal for benchtop, laboratory and  education applications.

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

Combined with a blackbody calibration source, the PyroMiniUSB makes the ideal calibration reference pyrometer. Keep one in your calibration room and check the performance of your other sensors against it. IOThrifty can provide calibration certificates for traceability.

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.

CalexConfig is simple, touch-friendly software for use with one sensor. It is supplied with the sensor. Features include:

  • Temperature display
  • Data logging to comma-separated text file (compatible with Excel)
  • Scrolling temperature chart
  • Sensor configuration

CalexSoft 2 is capable of displaying, graphing and logging temperature data from multiple sensors at the same time. It is available as a free download. Features include:

  • All the features of CalexConfig, plus:
  • View multiple sensors in the same software
  • Customize the screen layout with graphs and temperature displays
  • Scroll between multiple screens of temperature information
  • Configurable usernames and access levels (admin and operator

Since the outbreak of the Covid-19 pandemic, we have received a lot of interest in the use of our infrared temperature sensors for body temperature measurement.  These sensors are designed for industrial and laboratory surface temperature measurement.  They are not designed or certified for body temperature measurement or for medical use. Because of this IOThrifty does not warranty or guarantee their use in body temperature measurement applications
